  • Openness & Innovation,Hytera launched the latest Broadband Emergency Communication Products
    2020-08-17
    In 2020, the COVID-19 and some natural disasters seriously threaten the society health, life and property, and in face of such challenges, the emergency communication becomes more and more important for the first-response rescue of government.   For the overall promotion on the capacity of the emergency rescue, Hytera has rolled out the cutting-edge products and solutions for emergency communication in 2020. Recently, Dr. Guan Bao, the general manager of Broadband System BU of Hytera, gave a comprehensive introduction of these latest technologies and products as well as the expectation of emergency communication in the future. At the end of Q2 in 2020, Hytera has officially released its latest broadband products for emergency communication, and consolidated its leadership in professional communication in further. “The latest intelligent products were built on smart phone SoC with the advantages of high integration, super capacity, small form factor and low power consumption etc.,” Dr. Guan explained “We insisted on the 4G and 5G mainstream technology directions on the waveform design even though it’s more complicated. Under the 3GPP specification, we developed the industry-leading cognitive mesh technology, which significantly improved the anti-jam ability, and the radio link became more robust and stable. With the cognitive on network and service, it support more flexible topology and end-to-end QoS mechanism.” Dr. Guan highlights 3 latest products. PNE380: multi-mode mesh radio The PNE380 is featured with small form factor, and the weight of 288g is almost the lightest mesh radio in the industry. PNE380 is designed as a brand-new handheld radio that is capable of offering voice, data and video multimedia service, and similar to the traditional DMR radios in dimensions, appearance as well as usage mode.   According to Dr. Guan, the PNE380 performs great despite its small size and low weight. Firstly, the PNE380 can flexibly switch between the cellular mode and the mesh mode on customers’ demands, which enriches the application scenarios of the radio.  Secondly, with dual-band design, the PNE380 can work over both U and L band, and supports auto frequency scanning and selection, thus offering much better anti-jamming performance than the traditional single-band radio. Thanks to the superior signal processing capability of SoC chipset as well as the advanced technology of 4G and 5G, the PNE380 offers outstanding demodulation performance. Despite 0.5 watt transmit power, the single-hop distance with HD video service on the ground approaches to 1.5 Km with typical antenna, even longer than the distance of some backpacked mesh radio with high transmit power.  The PNE380 is powered with ARM cores and multimedia accelerators, and supports Android OS and customized Apps on actual demands.  Also, it provides rich peripheral interfaces for the flexible functionality extension.  In addition to high definition video services, the PNE380 radio can also offer various voice services through the Push-to-Talk over Cellular (PoC) software, such as trunking group call, multi-party conference and more. Dr. Guan said that Hytera will launch more smart mesh radios to further enrich product forms and improve the performance of the overall solution. Dr. Guan Bao noted that in addition to complete terminal products, Hytera is also engaged in module and board integration. Hytera is open to jointly develop innovative products with partners, promote the innovation of technologies, products and solutions through crossover cooperation, and build a more open ecosystem. Dome Camera over Mesh Network · The dome cameras are widely used in fire, public security, energy and other industries to capture videos in emergencies. At present, dome cameras feed live video over public networks. However, in many emergency situations, public networks might be unavailable or congested, resulting in video backhaul failures. This adversely affects decision making for emergency. · To solve the problem, Hytera together with its partners embeds the mesh module into the pedestal of the dome camera. Therefore, when public networks are congested, the dome camera can backhaul video to the command center over mesh network, which significantly improves situational awareness and facilitates decision making. The cost-effective and integrated pedestal can be easily installed and connected to PNE380, manpack radios, mobile radio, and other mesh products, which brings a more practical solution. Adhesive Communication Box The devices, no matter manpack, handheld, or wearable, will increase the burden on the first responders. As the first responders move or improperly carry the devices, the communication performance might be affected. Considering the emergency situations on the site, Hytera along with its partners has proposed the creative concept of adhesive communication box. Dr. Guan showed an upcoming adhesive communication box that weights over 400 g. The box is easy to be recycled and pasted to the wall, light pole and other facilities by reusable universal pastes. Thus, customers give the box a vivid nickname “chewing gum”. Featuring rich peripheral interfaces, the box also can be integrated with the AI edge computing module or Internet of Things (IoT) module, which further improves process capabilities and makes the box suitable for more scenarios. 5G technologies facilitate the development of the device-to-device (D2D) technologies, which have been widely applied to sectors such as the Internet of Vehicles (IOV) and Internet of unmanned intelligent devices. Dr. Guan pointed out, with the 5G-driven evolution of 3GPP-based mesh network technologies, Hytera will adhere to mainstream mesh network technologies and constantly upgrade mesh products. Based on unmanned drones and vehicles, 5G technologies shows great potential in the development of emergency communications toward the air-ground integration and man-machine coordination. “5G technologies will promote the comprehensive and leapfrog development of emergency communications.” Dr. Guan said. Hytera will embrace the opportunities and challenges to foster innovation, deepen cooperation, and expand the application of 5G in the field of emergency communications. According to Dr. Guan, radio communication is indispensable in emergency communications. Hytera’s e-Fusion emergency communications solutions have been put into commercial use and won a large number of customers in both domestic and overseas markets. With the launch of more new technologies and products, Hytera’s emergency communications products will develop toward miniaturization, intellectualization, and higher practical performance. Moreover, based on the modular design, Hytera expects to establish an open and innovative platform to enhance development of emergency communications.

  • Hytera PDC550 Assessment Report- Public-Private Integration and Broadband-Narrowband Convergence
    2020-07-02
    Written by PttCn Radio Assessment Lab At the 2019 Critical Communications World (CCW) event, Hytera showcased the smart PoC radio PDC550. PDC550 supports both DMR narrowband and broadband calls. I have obtained two PDC550 PoC radios recently and would like to share with you my using experience. I. Unpacking the box The PDC550 package in black is simple and compact. It includes a radio, an antenna, a charger, and a belt clip. The installation is also simple. The following figure shows the overall looking. PDC550 is characterized by the matte texture and two-color injection molding body. The radio is solid and elegant, and provides great tactile hand feeling. When you hold the radio in one hand, the position of the PTT key is just right for your thumb, ensuring smooth operations. PDC550 has unique design in details, which shows Hytera’s great ingenuity. The volume function and the channel switching function are integrated into one button, leaving more space on the top for easier operation of the emergency button. A colored ring is available at the bottom of the antenna. You may select any of the four colors to easily manage multiple groups. Secure belt clip design. Different from the common radios that secure belt clips with screws, Hytera PDC550 adopts a smarter design. To install the belt clip, users need to first remove the battery, insert the belt clip into the battery inner side, and reinstall the battery. Compared with the conventional method, this design is more convenient and no tools required. As a high-end, large-screen smart PoC radio, PDC550 is configured with a 5-inch HD industrial-grade touchscreen with a resolution of 1280×720. The multi-touch screen uses the third-generation Corning Gorilla Glass that is visible under strong light and supports operations with gloves and wet hands. Side keys 1 and 2 and the emergency key are programmable keys. Pressing the keys in a short time or a long time can trigger different functions. The following functions can be set via the app in the radio: Zone switching, emergency alarm, scrambling/encryption, power adjustment, mute/ringing adjustment, monitoring, network disconnection, scanning, camera, audio recording, screen capture, covert mode, etc. Compared with traditional radios that require professional programming software to set programmable keys, PDC550's programmable keys are much more convenient. PDC550 is IP68 rated. When we soaked PDC550 in water, it still worked normally. PDC550 comes with a standard 2400 mAh (optional 3500 mAh) battery, and the tested standby time is 45.5 hours (with 5% remaining power). When PoC communication software is enabled, to maintain the radio is always active for data receiving in real time, the PoC radio must keep alive link with the server. Under such condition, the tested standby time is 23 hours, meeting users' long working hour requirements in outdoor areas.  II. Professional Narrowband Radio Capabilities PDC550 supports 136-174MHz, 350-400MHz and 400-470MHz frequency.  And it enables digital and analog Direct Mode Operation(DMO) and Repeater Mode Operation(RMO) functions. The tested audio is clear and authentic. When two radios are getting close, no squealing sound is made. PDC550 uses dual-microphone noise reduction design to realize powerful voice recognition. It can accurately identify the user’s audio, and suppress noise in a noisy environment. Programming can be performed through settings on PDC550, which is much more convenient than that of traditional radios. The radio's standby frequency can be changed at anytime. In DMR mode, PDC550 can send short messages to a group or an individual with narrowband network. The operation interface is similar to a mobile phone's short message interface. Shortcut of sending predefined short messages is also supported. It is convenient to communicate with others even without public network. DMR outdoor test 1: test on coverage in residential area We selected a residential compound in Nanjing, China. Buildings in this compound are orderly distributed, and the total area is 0.6 km × 0.6 km. All the buildings have three floors. We carried out connection tests at each of the four gates (north, east, south, and west, with the north gate as the fixed point). With low TX power, the PDC550’s audio quality was 59. That is to say, in DMR mode, PDC550 can completely keep effective communications in this residential compound. DMR outdoor test 2: test on working distance We selected WenJing West Road (in Nanjing, China) for a test on the working distance of the radio from west to east. This road has heavy traffic, and most buildings alongside have three to six floors. PDC550 was tested that its normal communication distance between two radio is about 1.9km with low TX power and about 3.3km with high TX power. In a word, concerning the communication ability, PDC550 in DMR mode is comparable to professional two-way radios. III. Professional Digital Trunking Capabilities on Public Networks PDC550 has the Hytera’s software installed to support the public network trunking mode. Users can set priority of the DMR or PoC (Push-to-talk over cellular) functions on the radio conveniently. In PoC mode, PDC550 supports half-duplex individual calls, full-duplex individual calls, audio group calls, video individual calls, multi-party video calls, broadcast calls, and temporary group calls, etc. Over the LTE network, PDC550 supports multimedia messaging and can send texts, images, videos, recordings, location information, files, and SOS messages to a group or an individual. The UI design is similar to that of WhatsApp. Users can easily get familiar with it. With Hytera's professional dispatch platform, PDC550 can implement professional dispatch functions, such as audio dispatching, image and video uploading, and location tracking to meet various dispatch requirements.  IV. Data Services on Public Networks With abundant hardware configurations (such as the NFC, HD camera, positioning, and Bluetooth) and 4G networks, PDC550 can integrate with diversified apps to provide dedicated solutions, for example, QR code scanning, face recognition, license recognition, NFC card swiping and sign-up, and visual positioning. PDC550 is not only a radio but also a smart portable working terminal for users in different industries. V. Summary PDC550 is designed for high-end industry users to meet their requirements in different application scenarios, such as law enforcement, train, smart park, electric power, and water conservancy. Core features of PDC550 are scored as follows: · Push-to-talk function: 5 points PDC550 enables comprehensive functions of Push-to-Talk Over Cellular and contains main professional features with broadband network.

  • A high-end Smart PoC Radio Hytera PNC550 Assessment Report
    2020-06-29
    A high-end Smart PoC Radio Hytera PNC550 Assessment Report by PttCn Radio Assessment Lab Preface Nowadays, radio’s technologies and application scenarios are becoming diversified. With rapidly development of 4G/5G network, PoC radios are getting more and more widely used. Featuring wide coverage, diversified functions, and ease of use, PoC radios will develop rapidly and apply to a wider range in our daily lives and work. Today, we will introduce a high-end smart PoC radio Hytera PNC550 tested in the PttCn lab recently. I. PNC550 Overview The PNC550 package is compact and is similar to a Huawei P30 Pro smartphone package. A standard PNC550 package contains a radio, a battery, a power adapter, a data cable, and a HD screen protector. Users can purchase other accessories, such as the protective case, earpiece, desktop charger, tempered glass screen protector, Bluetooth ring PTT, belt clip and car kit based on actual application scenarios. The 156.5×76×14mm PNC550 weighs less than 250 g. It has a smaller size than an iPhone 8 Plus (158.4×78.1×7.5mm), but only 6.5 mm thicker. In my mind, at least the following three perspectives are considered in the design of PNC550: 1. Ultra-large screen like smartphones 2. Appropriate size to ensure convenient operations (in industries such as airports, logistics, and customs, a too small sized device is not user friendly for those working personnel who always need to wear gloves) 3. High dustproof, vibration-resistant, and waterproof quality PNC550 is equipped with a 5-inch HD touchscreen with a resolution of 1280×720, which is basically the same as that of an iPhone 6 or iPhone 7. The displayed content can be clearly viewed without any uncomfortable feeling. Similar to that of a smartphone, the screen’s upper part contains a receiver and a front camera (8MP). The screen’s lower part contains a bar speaker and a microphone. Unlike a smartphone that has a flat screen, the PNC550 screen is bulged in the surroundings and sunk in the middle. This design protects the screen when the radio falls down. On the left side of the device, there are four keys: power on/off, PTT, volume up, and volume down. The PTT key is about 30 mm long and surrounded with orange edges. There are six orange bumps in the middle to ensure accurately pressing the PTT key. The power, volume up, and volume down keys are round. The design is simple and beautiful. In other parts on the left and right sides, anti-ski and frosted texture design is adopted. The top and bottom part design is also simple. In the top right part, an orange emergency button is provided. The slightly convex key can facilitate pressing and prevent accidental touches. In the bottom part, there is a round metal plane on both the left and right sides for charging. And there is an earpiece port near the left side, a data cable (type C) port in the middle. The radio’s back design is similar to that of a mobile phone. In the upper middle part, there is a camera (13MP) and a flashlight. Under the camera, it is a rear cover. To ensure the reliability of battery installation and water resistance, a rear cover lock is designed in the lower part of the rear cover. The lock is locked when you slide it to the left and unlocked when to the right. Now you may have had a vivid understanding of the PNC550 appearance and some parameters. Among PoC radios, PNC550 is outstanding for the appearance design. In addition to a beautiful appearance, powerful features are very important to attract users' attentions. Next, let's see what PNC550 can do.   II. PNC550 Features PNC550 has a core self-developed software. This app also has simple design and includes group PTT call, video call, the messaging (P2P and group), contact, video uploading, emergency alarm, and setting features. It is easy to use. The following will describe several tests.   Test 1: audio fidelity The test was conducted at Starbucks, Jingxin Square, Jiangbei New District, Nanjing, China. The following table shows the tested devices and their purposes. Device Purpose Remarks Two PNC550s One is used to initiate calls, and the other is used to receive calls. The PNC550 to receive calls is set to six-level volume . iPhone 8 Plus Collects audio and converts it into text. The iFlytek app is installed. iPhone Xr Takes phones and records videos. iPhone 7 Plus Records and plays audio. We selected this Starbucks Coffee because it has large customer flow and a noisy environment (conversation, music, and skateboard sound outside).  Teammate A selected a corner at Starbucks Coffee to get the device ready for the test, and teammate B went upstairs to a place near the cinema on 4F (also crowded and noisy). B initiated a call to A and played the recorded audio "Today, we test the audio fidelity of Hytera PNC550 in a shopping mall environment." A used the iPhone Xr to take photos after PNC550 received the audio receiving and translated into text with iFlytek app . The text showed that PNC550 completed the task. That is, even in a noisy shopping mall, smooth communication is available with a normal audio volume. PNC550 has two microphones and uses dual-microphone noise reduction, which ensures clear audio transmission and receiving in noisy environments, such as shopping malls, trains, and airports. Test 2: voice volume Test 1 showed that PNC550 has clear voice transmission. In this test, we will quantify it. PNC550 is configured with a speaker with rated 1W power (Max 2W). In fact, it’s a standard configuration in the industry. Most iPhones (especially iPhone 6 and later) that provide good sound quality and high sound volume have a maximum power of 1 W.  We did a test to compare the PNC550’s(1W) audio quality with iPhone 8 Plus by playing a same audio (self-service automated prompt audio of China Mobile). We use a mobile phone to call China mobile and play self-service automated prompt audio in handfree mode. The first PNC550 received the audio and transmitted to another one. At last, we recorded the sound of second PNC550. And for iPhone 8 Plus, we did the same procedure. The data showing at follows: The preceding test data quantifies the PNC550 and iPhone 8 Plus speaker effect. We can see PNC550’s sound is much louder than iPhone 8 Plus. No matter the peak or average, the sound gap is about 10dB. (Generally speaking, when the gap is more than 3dB, our ears can clearly identify which sound is stronger and which is weaker). In terms of the voice quality and volume, PNC550 is a reliable radio. Test 3: HD photographed function This test aims to test PNC550 photographing capability. In addition to audio quality, most industries have increasing requirements for images and videos. PNC550 is equipped with an 8MP front camera and 13MP rear camera. This configuration is still very high level. People may think that a camera's photographing quality is determined by the hardware, and an 18MP camera must be better than a 15MP one. It is not true. Many people may think that whether the camera of phones or radio good or not is decided by the hardware is good or not. And 1800W cameras must be better than 1500W. Actually otherwise, the picture quality is essentially a math problem, in other words, a software problem. Users see photos. The camera captures basic materials. These materials compose a picture a large amount of mathematic computing and image optimization steps. For the photo quality, camera pixel is just a basic factor. The cameras for radios and smartphones are designed for different purposes. Smartphones are usually used to take photos of people and scenes. Therefore, smartphone vendors focus on people and scene image optimization, while radios are usually used to collect authentic and clear on-site information. The following figures show the photos taken in the morning, in the afternoon, and at night. Regardless of the day or night time, PNC550 completes photographing properly and can meet requirements in application scenarios, such as during law enforcement, in trains, and at airports. Test 4: backup time and charging time Backup time is also an important feature for radios. And we did test for this. PNC550 is equipped with a 4000 mAh Li-on battery and supports 2 A fast charging. The following table lists the tested data. Scenario Start Time End Time Duration 1. Standby mode 12:43, October 24, 2019 21:33, October 27, 2019 56 hours and 50 minutes 2. Charging 09:18, October 23, 2019 12:43, October 23, 2019 3 hours and 25 minutes 3. Call mode 14:34, November 23, 2019 16:37, November 25, 2019 21 hours and 17 minutes 4. Recording videos 09:37, November 21, 2019 16:58, November 21, 2019 7 hours and 21 minutes As shown in the preceding table, PNC550 can work for 56 hours and 50 minutes in standby mode. We have tested two scenarios. One is the online standby time, and the other is the offline standby time. 56 hours and 50 minutes is the online standby time. The offline standby time can reach up to 72 hours. The PNC550 charging speed is moderate but acceptable. For example, a Huawei Mate 9 with a 4000 mAh battery can be fully charged in about 110 minutes. However, PNC550 with a same-capacity battery needs to be fully charged in 205 minutes (3 hours and 25 minutes).  Users focus most on the backup time in call and video recording modes. We simulated the interaction frequency required in working mode and tested that the PNC550 backup time was about 21 hours and 17 minutes in call mode and 7 hours and 21 minutes in video recording mode, which can meet users' working requirements in various industries. Test 5: call quality in ultra-low temperature environment  In addition to powerful features and long backup time, PoC radios can provide stable communication in harsh or special environments. That is why mobile phones cannot be used as radios. PNC550 has passed Chinese SRRC, CTA, and CCC certifications, the United States military standard and FCC certifications, European CE certification, and Korean TTA and KC certifications. The PNC550 is IP68 rated, with a waterproof depth of 1 m, anti-fall height of 1.2 m, and working temperature of -20℃ to 60℃. We put a PNC550 in a refrigerator with -19℃ temperature for 1 hour. Then, we used another PNC550 to communicate with it. The call connection and answering were normal. In this test, we did not compare PNC550 with an iPhone.

In environments with insufficient lighting, you can hold the shortcut key for a little long time to turn on the flashlight conveniently. A strap can be attached to the top part which can make the radio easier to hold to avoid falling. PNC370 can be charged using a USB charging cable or a muti-unit charger. Common mobile phone charging cables that comply with Micro-USB standard can also be used. PNC370 has PTT and volume keys on one side and earpieces and charging port on the other. It is IP55 rated. The battery is installed on the back. The battery can be locked by sliding the lock catch to the left, enhancing reliability. The belt clip needs to be installed manually: loosen the two screws on the back, install the belt clip, and fasten the screws. The installed belt clip is stable and durable and will not fall. II. Tests on Call Features PNC370 supports 4G/LTE, 3G and WLAN networks and provides audio services via public networks. The tested PNC370 uses mobile 4G/LTE networks. Because mobile 4G networks have a wide coverage, PNC370 has full signal bars in most cases and two or three signal bars in indoor corners blind areas. PNC370 supports individual calls, group calls, broadcast calls, and emergency calls. Let's test the common individual and group calls. In trunking services, the most important and common calls are group calls. By default, the PNC370 PTT key is used to initiate group calls. After setting a defaulted group, you can press the PTT key with any interface on the screen even if the screen is off to initiate a group call, which is really very convenient. When PNC370 is unlocked, the PTT call status will be displayed on the screen. For example, if the initiated audio call fails, the failure reasons will be displayed. Typically, defaulted group is set on the management platform in a unified manner. The dispatcher adds radios to the group and sets the group as their defaulted one. Then, users can press the PTT key to initiate group calls. In command and dispatch center, the commander can use PNC370 to deliver commands to all group members at the same time. Compared with a mobile phone that sends notifications one by one, PNC370 is more convenient. To initiate an individual call, enter the contact interface from the main menu, select the contact, and press the PTT key. Users can initiate individual calls only when the contact screen is on. When the screen is locked, the PTT key can be used to initiate group calls only. PNC370 provides the P2 shortcut keys to finish quick operations in some scenarios. The design makes it easy to use. Users can press the P2 key to send alarms in emergencies. The alarm information includes the audio call. We have tested the call feature on two PNC370 radios. The call is set up quickly with low latency. III. Test on Positioning and Dispatch Features PNC370 is embedded with the GPS function and supports the GPS, BeiDou, and GLONASS satellite navigation systems and network-based positioning. By default, both positioning modes are enabled, and the positioning precision is high. After enabling PNC370 location monitoring in the Hytera dispatch platform background, we can know the accurate position of the PNC370 user in the background. The PNC370 uses network-based positioning indoor. The positioning error is within 20 m, which is relatively accurate. After PNC370 location monitoring is enabled on the dispatch platform, PNC370 reports the location information to the dispatch platform every 6s by default. We can record the radio movement track and use it for rescue or accident backtracking in emergencies. In long-distance working industries, such as logistics, we can monitor and control vehicle status, direction, and track on the platform, ensuring refined command and dispatch. In addition to location information, the Hytera dispatch platform can also collect audio and video data of radios. However, PNC370 does not support video calls. After the radio monitoring function is enabled, the dispatch platform will save users' audio information in a real time for control or as evidence. After obtaining user-related information, commanders can implement refined dispatch and unified command by initiating PTT calls to radios and groups through the dispatch platform. The test results showed that PNC370 cooperated with the dispatch platform properly. PNC370 reports accurate information to the dispatch platform in a timely manner, and the dispatch platform clearly and accurately analyzes and displays the information and sends accurate dispatch commands. It is a comprehensive solution and easy to use. And we believe it will be highly recognized by industry customers. IV. Other Main Features  1. PNC370 can achieve PoC communications through WLAN in the indoor blind spots areas and seamlessly switch between 4G, 3G, and WLAN networks. However, it does not support 9-key input method. To connect a WLAN network, users can open the soft keyboard to enter the password. 2. PNC370 supports call privilege priority. The professional call privilege management enables it to send emergency commands to preset users, groups, or important business types preferentially. The call privilege priority can be set on the management platform. 3. With Panasonic 3100 mAh standard Li-ion battery, PNC370 can continuously work for over 18 hours. 4. PNC370 supports IP55 dustproof and waterproof and complies with the U.S. military standard MIL_STD_810 G. Hytera has made many efforts in waterproof details of PNC370. The external interfaces, cracks of SIM card and battery interface are designed to be waterproofed. It is really exquisite.  5. PNC370 supports online upgrading system. Hytera PoC radios provides OTA (Over the air) upgrading. Users can update their systems online via a WLAN or 4G network. As the software keeps evolving, we can expect more user-friendly features.  V. Summary  PNC370 serves as one of the most basic terminals. It is quite suitable for some industries which require basic PoC communication. In hardware design, PNC370 inherits Hytera's military-grade quality, that is, exquisite, compact, solid, durable, and good texture.

  • Hytera PNC380 Assessment Report - A Safe and Reliable PoC Radio
    2020-06-22
    Written by PttCn Radio Assessment Lab Two-way radios are widely used in different industries. Traditional analog radios, although convenient, serve only short-distance communications and are vulnerable to interference. In contrast, PoC radios (Push To Push Over Cellular Radios) are functional wherever there is internet access, with no need for FM settings or relay station deployment. Besides PoC radios enhanced features such as anti-interference capability, radiation-free communication, high quality audio and long battery time. They are becoming more and more popular in various industries. Today, I will test the latest PoC radio PNC380 from Hytera, a global leading PMR solution provider.  I  Unpacking the box As shown in the preceding figure, standard accessories of PNC380 radio include a user manual, a battery, a data cable and power adapter, a strap and a belt clip, which can meet most users' requirements. Wired earpieces, wireless earpieces, and wireless ring PTT (for those who communicate in an invisible way) are optional.  The charging port at bottom is sealed with a piece of soft rubber, which better prevents water and dust from entering. There is only one dedicated orange emergency key on the top of the radio. In emergencies, you can easily and accurately press the key to send an emergency call. On the left side, a programmable key is provided in the upper part, and a PTT key is in the middle. The large-size PTT is easy to locate and can prevent accidental touches. The volume up and down keys are under the PTT key. On the right side, the earpieces port is sealed. Open the rear cover, we can see that the device body is sealed with a stripe of orange soft rubber, providing superior water and dust resistance. The housing is solid and durable. The rubber keys have proper hardness and good tactile feeling. The back anti-slip texture design ensures proper holding and prevents dropping even in sweaty palms. Here are some other pictures of PNC380.    II  Testing Functions 01 Group call test PNC380 supports various voice services, such as individual calls, group calls, full-duplex individual calls, and emergency calls. In trunking services, the most important and common calls are group calls. Now I will test the group call. Turn on the radio, then the pre-installed app automatically started, and the radio joined to the default group. The following figure shows the app homepage. Hytera PNC380 also solves the time-consuming issue of call setup. After you power up the PNC380 and log in to the system, the radio automatically joins the default group, and the group is always online. Each time you press the PTT key, you apply for the talk right. As group call related resources are prepared, the talk right can be applied for in 200 ms to 500 ms.  The actual test result showed that talk right application is fast. Basically, you can talk upon you press the PTT key. The calling and called radios' prompts showed that the calling and called parties' voice was almost heard at the same time. I tried to apply for the talk right for dozens of times, and only in one or two attempts that the called party's voice was delayed slightly. In addition to a good talk right application experience, the PNC380 shows excellent performance even for some details during calls A. When being connected to a group call, the user may be in either the 'call in process' state or the 'idle' state of talk right, which can be identified by checking the indicator and prompt tone. In the idle state, when you press the PTT key, you can hear a clear tone, and the indicator turns red, indicating that the talk right is assigned. When the receiver receives the prompt of such talk right, the indicator changes to green and you and the receiver can start talking. In the 'call in process' state, when you release the PTT key, indicating that the radio enters the 'idle' state. B. By default, radios in the same group have same priority. When the user in receiving state applies for the talk right, a prompt 'Floor operation was rejected' is displayed on the screen. Users such as the team leader or senior who have higher priority talk right can cut into a call. C. The default talk right duration is 60s. After the user is in talk right preemption state for more than 60s, the message "Floor revoked" is displayed on the screen, a prompt tone is heard, and the radio vibrates.  It’s a user-friendly design especially for first-time user. It is quite abrupt if you are forced to end the talking after 60 seconds without any prompt. Maybe, you will consider the system is getting wrong. End the talking after a fixed time is currently widely used, as it prevents the talk right from being occupied by a certain user. All the tests show that PNC380 call services feature simple operations, a high successful rate and high speed for talk right application, short talking latency. The call services of PNC380 is as professional as two-way radios. The PNC380 talking program is stable. I had tried many methods to break down it, for example, applying for the talk right frequently in an area with weak Wi-Fi signals. However, the program seldom breaks down. Even if it breaks down, the system will restart it immediately, and soon you can experience the call services. The performance is much better than other PoC radios who once encountered talking program breakdown, cannot resume normal operation unless being restarted.  02 Sound Quality Tests For cost considerations, most PoC radio vendors use single-microphone noise reduction. However, PNC380 uses dual-microphone noise reduction, which provides a better audio.  Dual-microphone noise reduction enables PNC380 to accurately identify user’s voice, and suppress ambient noise in noisy environments, such as on downtown roads and in shopping malls. I worried that the excellent noise reduction performance may affect the volume. However, the test result showed that the built-in 32 mm round speaker provides clear voice. 03 Waterproof Tests PNC380 is IP67 rated and complies with the MIL-STD-810G standard. After I took the PNC380 to a sauna room for more than 30 minutes, it still provided stable and high-quality call. Its structure design is really great. It is still working even when I soak it into water. Along rivers, you will no longer worry about water leakage or sediment erosion. I think radio users must be very familiar with IP67, so I will not go into details. Those who are unfamiliar with it can search for more information from the Internet. Now let me introduce the MIL-STD-810G standard. MIL-STD-810 is a United States military standard that emphasizes on tailoring equipment's environmental design and test limits to the conditions that it will experience throughout its service life. Although prepared specifically for military applications, the standard is often used for commercial products as well. The MIL-STD-810 standard has eight versions from A to G, and G is the latest version with the highest requirements. 04 Positioning Feature Test The positioning feature of PNC380 is also distinctive. It supports the GPS, AGPS, BeiDou, and GLONASS positioning systems for quick positioning anytime, anywhere. It can also be connected by a WLAN, Bluetooth, or mobile network for indoor positioning. These ensure a seamless indoor and outdoor connection. We tested the positioning feature in a neighborhood. Our position can be accurately located, and the displayed routes indoor and outdoor are basically the same as the actual ones. The monitoring center can monitor positions of frontline personnel in real time, and dispatch them promptly.  III  Summary Hytera PNC380 is a high-quality PoC radio with abundant and powerful features such as quick and convenient operations, loud and clear audio, stable communication, excellent dustproof and waterproof performance, and accurate positioning. It supports 2G,3G, 4G/LTE, and Wi-Fi networks. When working with Hytera professional dispatch platform, it applies to various business scenarios.  Will you want to experience group call communication the same as Hytera PoC radio?

  • Assurance of safety for your reopening: Hytera unveils pandemic prevention solution for smaller organizations
    2020-06-04
    Hytera has launched a simple, but highly effective pandemic prevention solution for small- to medium-sized organizations such as schools, enterprises, retail stores, and shopping malls. Hytera body temperature measurement solution provides a non-contact way of detecting people's temperature for reducing the risks of being infected, and helps to create a more secure and safe environment from the moment when people come into work. With countries gradually coming out of lockdown, it is vitally important to detect whether any employee or visitor has an abnormal temperature when they go back to work, to school, or to visit shops. It is critical this is done effectively and efficiently to help organizations quickly process people as they enter a building. Employees overseeing the temperature measurements must also be protected. Manual temperature screenings using thermometers and infrared detection guns are slow, inefficient and unsafe as they increase the risk of cross-infection. Manual recording of personal information on who is entering a building is time consuming and inefficient.  Hytera body temperature measurement solution provides smaller organizations with a facial recognition and remote temperature checking solution that is easy to set up and operate. It ensures safe operations both during the pandemic and in the subsequent recovery period after lockdowns are relaxed. The Hytera body temperature measurement device can be quickly mounted on a tripod and set up at the entrance, reception areas, offices or anywhere that is suitable in the building. Facial recognition technology checks the person who is against a database. At the same time, the detection device remotely, automatically and accurately measures the person’s temperature, including those wearing masks. If the temperature is abnormal, the device immediately sends an alarm notification to Hytera handheld terminals such as the PoC radio PNC550 or multi-mode advanced radio PTC760. Security personnel standby can then re-check the person’s temperature and take appropriate action to isolate them and arrange treatment with the instant and reliable communications provided by Hytera radios.  The face, temperature and entry time records are logged onto a database using backend management software. These records can be used to test and trace people who have been in contact with someone running an abnormal temperature. This ensures a much faster response when seeking to contain the spread of any new COVID-19 outbreak. The Hytera body temperature measurement solution provides small and medium-sized organizations with a simple, safe and effective method to screen relatively large numbers of people entering a building besides immediate and reliable communications. Hytera is assuring the efficiency and safety of those organizations aiming to return to work after lockdown. Please click HERE for more information about Hytera body temperature measurement solution.
  • #LIVE: Frontline in the city
    2020-05-29
    First responders are facing growing public safety challenges every day, and they need reliable radios supporting both legacy PMR voice services and modern broadband applications to respond quickly and effectively to these challenges.  Let's see how Hytera multi-mode advanced radio with RoIP solution enables public safety personnel to concentrate on the tasks that matter most.  Traditional narrowband professional mobile radio (PMR) networks often have limited coverage, and they are unable to support rich multimedia broadband communications, which are increasingly in demand by emergency services and mission-critical communications users.  Hytera multi-mode advanced RoIP-enabled radios fulfill this need.  Hytera multi-mode advanced radios with RoIP solution enable seamless roaming with auto network switching and multiple-mode access with the same ID. When public safety staff members are outside the narrowband network, they can talk to each other using the public broadband network. RoIP solution provides video services over the broadband network for first responders. Its intuitive operation also makes the response more effective.

  • Hytera Multi-mode Advanced Radios with RoIP Solution Enhance Public Safety Response Efficiency
    2020-05-21
    Hytera multi-mode advanced radios with RoIP solution provide public safety personnel with a vital tool to help them carry out their jobs more efficiently. Hytera RoIP solution based on the convergent broadband and narrowband platform deliver both multi-network roaming and fast broadband services such as video calling.   First responders are facing growing challenges worldwide from public safety crises such as terrorist attacks and pandemics, as well as environmental disasters like wildfires and floods. Public safety personnel must be able to respond quickly and effectively to these challenges. Hytera multi-mode advanced RoIP-enabled radios fulfill this need. These smart, easy-to-use radios reduce workloads and allow public safety personnel to concentrate on the tasks that matter most. What is RoIP Traditional narrowband professional mobile radio (PMR) networks often have limited coverage and they are unable to support rich multimedia broadband communications, which are increasingly in demand by emergency services and mission-critical communications users. However, mission-critical instant push-to-talk (PTT) voice services still play an essential role in the daily work of public safety personnel. The solution is to deploy Hytera multi-mode advanced radios that retain mission-critical voice communication, but which also support the new broadband applications public safety organizations want to access. Hytera RoIP solution, a form of Voice over IP (VoIP) with mission-critical PTT feature, combined with Hytera HyTalk Pro and narrowband trunking system provides an intelligent platform to deliver integrated narrowband mission-critical one-to-one and one-to-multiple voice services, and a wide range of multimedia broadband services such as video calls, video pulling, multimedia message and mobile internet access over 3G, 4G, WLAN and private LTE networks. This deep integration delivers a unified communication experience and a more luxurious convergent experience to users. One of the essential keys to this convergent experience is the intelligent network selection mechanism whereby the radios automatically switch between narrowband and broadband networks base on the signal strength and preference. The multi-mode advanced radios preferentially access the narrowband network for voice services, but if there is a weak or no signal, the radio will automatically switch seamlessly over to the broadband network. The radio ID remains the same whichever network is being used. Three typical user scenarios 1. Emergency response The RoIP solution in the radios ensures the police officers responding to an incident have access to reliable, always available, instant voice communications. When they are outside the narrowband network, they can talk to each other using a public broadband network. Officers can stream live video to control room dispatchers, which improves situational awareness, enabling police to make better-informed decisions and to deliver a more effective response.  2. Firefighting Firefighters entering buildings, basements, or tunnels may lose their narrowband network signal, but the RoIP in their multi-mode advanced radios enables them to continue the communication with each other using public broadband networks. Firefighters can use the broadband capability on their radios to connect to hands-free Bluetooth accessories, which can monitor their vital signs and report relevant information to the command center in real-time.  3. Wide range patrol Police on wide range patrols can rely on intelligent network selection and intuitive radio operation to keep voice channels on the radio available. If they patrol out of the narrowband network coverage area, the radio will switch automatically to the public broadband network without the user's awareness of the change.  Hytera also provides a range of smart accessories, including Carkit and convert camera. The radios can be mounted in the patrol car using a Carkit and connected to a larger display like a tablet. The VM220 convert camera with headset allows police officers to talk, record video, and transmit it to the control center in real-time - all without holding the radio.

  • Hytera Anti-Pandemic Solutions Help Contain the Virus Crisis
    2020-04-13
    The recent outbreak of COVID-19 has affected all of us. Given the difficulties the world is currently facing at this time of uncertainty, Hytera has developed a new solution to help those who are on the frontline of battling the disease, including customs police officers, healthcare workers and enterprise staff. The solution aims to combat the spread of COVID-19 by using fast deployable, non-contact body temperature detection and communication technology. Enables customs to monitor anytime, anywhere Land border crossings and immigration customs control points at ports and airports are particularly vulnerable areas as large numbers of travelers pass through them on a daily basis. If it is possible to detect that someone has an abnormally high temperature at the border, it becomes easier to reduce the risk of the infection spreading at home and abroad.  Hytera has developed a safe, efficient and precise way to measure the body temperature of travelers using non-contact methods. The solution provides a way to remotely detect the body temperatures of multiple persons at the same time up to a distance of 3m with no risk of close touch infection. An automatic warning is triggered and sent to Hytera PNC550 PoC radio devices if an abnormal temperature is detected. The person whose temperature is abnormal can then be isolated, re-checked, and sent to hospital if necessary. The solution saves a lot of time and manpower, as it provides a way of screening large numbers of people simultaneously at border posts, thereby getting round the near-impossible alternative option of having to check people's body temperatures manually, one at a time, which would involve close contact. Deployment of Hytera VM780 body worn cameras (BWCs) also helps to protect the safety of travelers and customs officials. Border controls can lead to confrontations between officials and travelers, but BWCs can help defuse tense situations as people usually calm down if they know they are being filmed.  The video footage can provide hard evidence of what happened in an incident to verify the truth of the traveler's or the official's account. Video can also provide transparency to ensure officials are conducting themselves according to regulations. The Hytera VM780 enables live streaming over 4G/Wi-Fi networks. It greatly enhances situational awareness for officers in the field and for supervisors in the control room, as well as helping to keep personnel safer. Ensures hospitals run effectively and safely  In the healthcare environment, hospitals need non-contact detection methods to process people entering the hospital to reduce the risk of cross-infection of staff, who must be protected so they can look after their patients. Non-contact detection equipment is needed at the entrances of hospitals to try and identify people with abnormally high temperatures before they progress any further into the building.  The solution involves setting up a Hytera temperature measuring device equipped with accurate facial recognition and remote temperature measurement technology at gates, reception areas, offices or anywhere that is suitable. Once again, if someone is detected with an abnormal temperature reading, then an alert is sent via the mobile radio app to the Hytera PNC550 PoC device.  The technology is able to recognize faces even if the person is wearing a mask. This makes it easy to distinguish between employees and visitors. The solution automatically generates entry records detailing the person, their temperature reading, what time they entered or exited the building and so on, making it easy to trace people. To reduce the risk of infection, doctors can use their Hytera PoC radios to make remote diagnoses and to discuss each patient's case with colleagues using group video call or one-button instant audio call. This avoids close touch situations and helps to keep hospital staff safe. In addition, the PNC550 PoC radio's 5-inch touchscreen supports full operation using gloves, which further helps to protect staff from infection.  Bodycams can also record video footage of medical inspections and treatments in the hospital. The videos can not only be used as evidence during medical disputes, but can also be shared as training materials to enhance the quality of future medical services. Ambulance paramedics can use Hytera VM780 bodycams to stream live video from the ambulance back to the hospital to provide doctors with real time monitoring of the patient's situation. The hospital has an early warning of the state of the patient and can set up the appropriate response ready for when they arrive. Doctors can make remote diagnoses and provide advice to the paramedics, potentially enabling vital medical interventions to be made on the way to the hospital. Again, the video can be used as evidence in the event of any later medical disputes.  A worry free solution for enterprises Enterprises can also make use of the solution by installing Hytera temperature measuring devices at the gates or lobby entrances to buildings. This will detect whether any employee has an abnormally high temperature as they come into work.  Again, if the device detects anyone with a high temperature, an alarm will be triggered and sent to the security guards' PoC radios and to a control center if there is one. The solution is very flexible and easy to deploy and could also be set up in large apartment buildings, metros and railway stations. The availability of reliable communication services means professionals can better safeguard citizens both in times of crisis and in normal day-to-day operations. Hytera's solutions are helping the global community fight the COVID-19 pandemic. The ability of various authorities to collaborate smoothly together at all times helps create a safer society.

  • Four Concepts of Hytera's Emergency Communications Solutions
    2020-03-03
    Strong technological support is critical while people strive to improve the disaster prevention, reduction and relief capacity and to achieve leap-forward development in emergency communication. As an integral part of the informatization of emergency management, construction of emergency communications infrastructure has long been a focus of attention. Private network communication vendors also consider emergency communications a strategic direction and continuously innovate to adapt to increasingly complex and diversified social demands. Hytera has vigorously promoted the scientific and technological progress in emergency communications. Recently, in an exclusive interview with PTT Communication, Mr. Song Qintao, General Manager of Hytera Command & control & emergency response product line, shared Hytera's conception and understanding of emergency communications; product development concept; R&D process, technological advantages and future plans of the company's ad-hoc network.   I  Emergency response, a deep-rooted element of Hytera The establishment of the Ministry of Emergency Management of the People's Republic of China in 2018 added weight to strategic prominence of emergency management. All sectors have made full use of their own advantages to fuel the development of information-based emergency management. With years of experience in emergency communications, Hytera is well positioned to promote the development of the industry. According to Song Qintao, since its founding in 1993, Hytera has proactively explored the private network industry for 26 years and has achieved global and industry-wide development spanning over all systems and product lines. Featuring outstanding real-time operation, invulnerability and security, private networks have the innate strength to excel in emergency communications. In addition, Hytera has developed coincidentally being in step with the development of China's emergency communications industry. Disasters such as SARS, the Wenchuan Earthquake, and the snow storms in China in 2008 have fueled the demand for emergency communications products. In response, Hytera established an emergency product team consisting of around 300 people to explore user demands and pursue innovations. After years of development, Hytera has created a large number of emergency communications products such as broadband and narrowband ad-hoc networks, converged communication and on-site command and control centers, and obtained dozens of patents. Moreover, years of interaction with target clients in emergency-prone sectors such as public security, firefighting and forest fire prevention have enabled Hytera to gain a deeper understanding of emergencies and accumulate high-level expertise required by technology and product development. Song Qintao noted that, as of today, Hytera's emergency communications solutions have been successfully applied to a variety of emergency scenarios such as general early warning, natural disasters, accidents, public health events, social security incidents and major events. Hytera is one of the few enterprises in China that can provide a complete set of emergency communications solutions.  II  Four concepts of Hytera emergency communications solutions Long-term accumulation of experience and systematic theoretical analysis have enabled Hytera to refine four concepts that are needed when building emergency communications: " Full-regional coverage and support all kinds of scenarios, large and small network applications, integration of existing resources and new resources and front and back connection". Song Qintao explained the four concepts in detail. 1 Full-regional coverage and support all kinds of scenarios.  Hytera strives for full-regional coverage and support all kinds of scenarios. Since an emergency usually occurs unpredictably, the emergency communications network must achieve full-regional coverage rather than only providing coverage in densely-populated areas and key areas. Full-scenario support means that, to meet the needs of a diverse range of scenarios, a wide range of services are provided, including command and dispatching, voice communication, data transmission, positioning and intelligent perception. 2 Large and small network applications.  This refers to the "use of a small network for large disasters and a large network for small disasters". Generally, for an emergency event which occurs in a smaller area, the existing PMR network and public network are adapted to the emergency requirements, and this is the "use of a large network for small disasters". While for major disasters such as the Wenchuan Earthquake and Jiuzhaigou Valley Earthquake, many infrastructure facilities were destroyed and the PMR trunking base station dumped and public networks broke down. Under these circumstances, the ad-hoc network integrating narrowband and broadband services is the only option to build a "small network" and set up a "large network" through these "small networks" to quickly restore field communications. 3 Integration of existing resources and new resources.  Existing emergency communications network resources include different networks previously built by different departments. These basic communication resources must be used more effectively. On this basis, new devices and new technologies are added to achieve integration of legacy and existing resources and interworking. Hytera provides a strong converged communications platform, which can integrate all types of devices and guarantee smooth communications. 4 Front and back connection.  The field personnel at the front end, middle command layer and command center at the rear command and control center are completely connected to achieve multi-layer instant communications. The most critical part is to reduce the hierarchical dissipation of information transmission, guarantee the integrity of information transmission, and continuously improve communication efficiency. Based on these four concepts, Hytera believes that an emergency communications network covers three main dimensions:  Nationwide coverage of DMR on the entire network. Based on the DMR network, a perception network can be overlaid to monitor disasters on a large scale. Public network resources featuring wide coverage, rapid technological evolution and strong functions. Networks supporting flexible and rapid deployment. Under the guidance of the four concepts, Hytera has built a complete emergency communication architecture from the terminal layer, network layer and platform layer into the application network. III The ad-hoc network has its unique value Hytera's emergency communications covers the design of a system-wide series of products. So far, Hytera has developed a series of products such as narrowband ad-hoc network product E-pack, broadband ad-hoc network product iMesh, portable emergency command center E-center, digital wireless ad-hoc repeater E-pole and IoT Data Modem (IDM). Among them, E-pack, iMesh and E-center are leading ad-hoc network products in the industry and are widely used in the emergency field. Song Qintao believed that the core advantage of ad-hoc networks lies in their "ad-hoc" features. For conventional communication, optical fibers are required to work with base stations for large-area coverage. However, when a disaster happens, optical fibers may no longer be present and transmission equipment can only cover part areas. How can communications between two or more points be achieved? An ad-hoc network can effectively solve the issue of signal coverage, because point-to-point connections automatically occur among multiple points to generate larger points, thus achieving large-area coverage. The ad-hoc network overcomes the geographical limitations of traditional networks. Ad-hoc, self-recovery, self-healing, multi-hop routing and dynamic topology enable the ad-hoc network to achieve temporary networking, rapid extension and high invulnerability and support fast, convenient, and efficient deployment to achieve large-area service coverage. In addition, Hytera's ad-hoc network is fully compatible with the PDT and DMR standards instead of adopting a private protocol. This allows Hytera's ad-hoc network to connect to different devices and help meet emergency requirements nationwide. Moreover, Hytera's ad-hoc network devices are smaller and lighter, and provide larger coverage. For example, the voice ad-hoc network device E-pack weighs only 3.6 kg, boasts a 10-hour battery life, and supports on-board charging. Hytera's ad-hoc network devices has passed scenario testing and with their industry-leading coverage and networking capabilities proved in applications. IV Create new value for global customers Hytera emergency communications solution is widely used around the world, which creates new value for users. Hytera explores the concept of a "Safe Resilient City" in Nanshan District, Shenzhen, to help build a smart Nanshan city operation command system and form a "1+8+1" pattern (the first "1" refers to the command and dispatching center, "8" refers to 8 subdistrict offices under jurisdiction and the last "1" refers to the secondary emergency command center of Nanshan District). Hytera builds a private IoT network, which can perceive change in the water level and inclination of billboards. More importantly, Hytera closely combines IoT perception with command and dispatching so that problems that are found can be rapidly handled to form closed-loop management. This played an important role in emergency response to Typhoon Mangkhut in Shenzhen. Hytera's emergency communications solution is also used in international political, economic, and cultural activities. For example, ad-hoc networks have played critical roles in APEC Summit held in Papua New Guinea, tsunami relief in Indonesia, Cambodia's national election, earthquake response in Jiuzhaigou (achieved whole-network coverage in the earthquake-stricken area with only three ad-hoc network devices), and security work during opening ceremony of Hong Kong-Zhuhai-Macao Bridge. With technologies evolving, Hytera has developed a technical system based on private networks and IoT, created layouts pertaining to each aspect of disaster prevention, reduction and relief, and continuously innovated to provide inexhaustible development for emergency management.  V  Innovate continuously to promote development of emergency communications There is an urgent need for a modern emergency management regime that is systematic, flattened, integrated and user-friendly, and this puts forward higher requirements for technological innovation. Song Qintao said Hytera will continuously promote development of emergency communications towards intelligent, diversified and small-sized products based on the following concepts: 01 Intelligent products While promoting region-wide coverage, Hytera will also continue to step up research and the use of perception, and achieve smart perception to provide emergency communications wherever it is needed. 02 Diversified technologies Hytera is committed to promoting public-private integration and broadband-narrowband convergence. By combining all available communication methods, Hytera will provide users with a wealth of information and achieve communications between anyone at anywhere anytime in any form. 03 Small-sized devices Portable devices can significantly enhance the capabilities of individuals and improve teamwork. In future, Hytera will launch smaller and lighter devices that have bigger capacity batteries, and emphasis would be placed on the compelling need for deeply integration of emergency communications with the next-generation technologies such as cloud computing, big data, artificial intelligence and mobile Internet. Clearly, there is still a long way to go, and Hytera will continue to innovate and forge ahead! Article from PTT Communication

  • What can Hytera do for you to better control the scene of a mega event
    2020-02-21
    2020 is a big year for sports. Important sports events such as the Olympic Games, European Football Championship and World Cup Qualifiers lie in store. Globalized development has become a trend. More and more large global, intercontinental and national events are held every year. Innovative communication technologies play an increasingly prominent role in ensuring security at mega events. However, in face of security requirements for mega events, traditional communication technologies are facing great challenges. How to organize events in an orderly manner, maintain order on site, guarantee smooth and orderly processes and quickly respond to any accidents… Of these requirements, using communication technology to realize smooth communication inside and outside the event site becomes key in ensuring security at mega events. Three challenges in guaranteeing communication for security at large events Challenge 1 Heavy task and high requirements National or global large conferences, artistic performances, celebrations or sports events will gather thousands, tens of thousands or even hundreds of thousands of people in an area and may involve leaders from countries around the world. It causes great international and social influence. The security assurance requirements reach an unprecedented height and the entire communication network should be ready anytime and anywhere without any risk. The system is required to provide multiple levels of guarantee and fully respond to any emergency. The requirement close to “zero error” is put forward for communication guarantee in security assurance for large events. Challenge 2 Short duration of the event A mega event usually lasts for several days or weeks. It is relative short. A mega event always requires a temporarily solution that supports quick deployment and convenient installation and uninstallation. Challenge 3 Lack of bandwidth and on-site information Ensuring the security at a mega event requires real-time multimedia communication guarantees at the event site and roads around the site, including HD video surveillance and video conferences. However, traditional security work usually does dispatching and accident reporting only via narrowband voice intercom. Less information can be obtained as it is short of live on-site video as well as photos and images. It is difficult to make accurate judgments as quickly as possible. Hytera's mega event security solution will help customers set up smooth communication at mega events In face of challenges in providing communication at mega events, Hytera can provide portable base stations to set up the broadband and narrowband ad-hoc network. The solution effectively solves the issue of communication between security personnel on site and communication of the command center and guarantees that the event can be carried out smoothly. Main benefits are listed as below: 01 The solution provides an all-round communication network featuring professional reliability, flexible networking, fast deployment and broadband and narrowband convergence, and meets requirements in scenarios such as indoor and outdoor security assurance, security for very important persons and emergency response.  For security assurance at mega events, Hytera provides communication equipment that uses innovative wireless ad-hoc network technology. The equipment features portability, fast communication, flexible networking, dynamic network topology, broadband and narrowband convergence, realizes seamless integration of a wired network and provides large coverage. The equipment is easy and convenient to use. The system capacity is large; key voice services guarantee transmission in preference; the private network is used for special purpose; and security level is high. The equipment can meet communication guarantee requirements in scenarios such as indoor and outdoor security assurance, security for very important persons and emergency response. For example, in the aspect of narrowband ad-hoc network, in scenarios such as security for very important persons or prisoner escort on the expressway, Where there is poor signal coverage of main PMR network or a dedicated communication network is required, E-pack ad-hoc repeater can set up a temporary network with mere battery button press-on via auto networking. Due to auto-networking and self-organizing features, the networking structure is adjusted dynamically to guarantee smooth communication. The fleet interconnects with the station command center via a GSM link to communicate on the progress and the station deploys command and dispatch software to realize command and dispatch for the fleet. In the aspect of broadband ad-hoc network, at large group events and important conferences, real-time multimedia communication guarantees shall be provided for the event sites and roads around the sites, including HD video surveillance and video conferences. For the infrastructure at event sites, not all sites are provided with optical fibers to guarantee information backhaul. Hytera iMesh broadband ad-hoc network devices can be used to establish a broadband wireless ad-hoc network to transmit video and data of all nodes back to the command center. Up to 60 Mbit/s throughput and 4K HD video service are supported. 02 The solution provides efficient and intelligent command and dispatching. The front-line security personnel, on-site command and dispatch center officer, and rear command and dispatching center officer communicate seamlessly. In Hytera's mega event solution, the emergency command vehicle is deployed on the periphery of the large venue as the mobile command and dispatch center. It receives site information from mobile police cars and provides command and dispatching on site. The on-site command and dispatching center deploys a unified command and dispatching platform (PUC) and integrates the core network, network management system and vehicle-mounted broadband ad-hoc network devices. The mobile command center transmits site information back to the rear command and dispatching center via microwave, satellite or 4G public network. Equipped with multi-mode advanced radios, front-line security personnel communicate with the outside by means of voice services via voice ad-hoc network and connect to iMesh portable radios via Wi-Fi to transmit video and data back to mobile police cars. 4G private network base stations can be deployed near the mobile police cars and field surveillance dome cameras and LTE terminals can be connected to 4G private network base stations to transmit on-site surveillance video signals to the mobile police cars. The mobile police cars also carry iMesh vehicle radios as information transmission nodes, which transmit collected video data to the mobile command and dispatching center via iMesh links. Rich practical experience Relying on more than 20 years of industry experience in private networks, Hytera has participated in communication guarantees for large Chinese and international events many times. For example, Hytera successfully provided communication guarantees for the APEC Summit held in Papua New Guinea in 2018 by using its emergency ad-hoc solution; Hytera successfully provided communication guarantees for the national election of Cambodia in 2018; during the G20 Summit held in Hangzhou in 2016, Hytera provided a communication guarantee service of the highest level for ensuring the security of more than 30 heads of states and officials from international organizations; during the BRICS Summit held in Xiamen in 2017, Hytera built a global security three-dimensional communication network of the highest security level to provide highly stable and reliable communication guarantees from core areas of the Summit to inside and outside Xiamen Island and nearby seas.
