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
Hytera 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 two way 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, Hytera 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.
