Professional Mobile Radios

Key Features of Professional Mobile Radios

Due to the openness of various standards of professional mobile radios, in the process of technological development, the professional mobile radio systems provides the security, scalability and functions required by professional communication networks. The main features of professional mobile radio systems include:

• One-to-many Communication

  Different from the point-to-point communication of mobile phones, professional mobile radios can communicate one-to-many. The transceivers of all radios are usually in the receiving state. If any radio initiates a speech, all radios on the same frequency channel can listen to the call.

• Push-to-talk

  Push-To-Talk connects you and your teammates quickly. When you press the PTT button, your voice is transmitted to other players on the same channel as you for a short time. This helps provide communication efficiency and get work done quickly.

• Security and Encryption

  For mission-critical environments, such as frontline public safety, the importance of maintaining a secure, private network is paramount, and professional mobile radio systems require security mechanisms to provide security throughout the business process and multiple layers of end-to-end encryption.

• Large Communication Range

  The communication range of a single professional mobile radio is limited. We can increase the communication distance by increasing the transmission power or raising the antenna, or we can expand the range through repeaters. With a trunking system, multiple base stations can be connected and provide wider coverage than a single base station.

• Call Priority

  Professional mobile radio systems are mostly half-duplex, where multiple radios share a common radio channel, only one can transmit at a time, and you won't be able to transmit when someone is occupying the channel. However, you can set the priority call right, so that in an emergency, you can directly press the PTT button to forcibly interrupt the existing call and send an emergency message.

• Different Communication Frequencies

  Professional mobile radios usually use UHF (Ultra High Frequency) or VHF (Very High Frequency) frequency bands in different scenarios to obtain better communication quality. UHF performs well in penetrating walls and concrete at close range, and works better in indoor and urban areas. VHF can travel farther with few obstructions, so it is ideal for long distances. Whether it is UHF or VHF, they all need to be on the same frequency to communicate with each other.
