POC radios mean Push to talk over the cellular. Using the cellular network, you can talk to your members without a distance limit.
Our Retevis RB21 is a Push-to-Talk over cellular radio, which is different from the traditional walkie-talkie and mobile phones. POC radios use the existing mobile communication network for interaction.
Compared with the ordinary walkie-talkie, it has many advantages. There is no need to apply for a license for POC radio. The signal coverage of it can reach the whole country, which breaks the distance limit of a traditional walkie-talkie and saves the expensive repeater cost. Moreover, it also has a GPS tracking system. Through computer terminals, you can track the location of employees, which is greatly helpful to improve work efficiency.
