POC - is a PTT (Push-to-talk) call over the cellular network. In other words, it is a technology that uses a broadband cellular network and a broadband WiFi network to build a network and organize communication between subscribers. This technology is able to provide reliable and secure communication over long distances without deploying a radio infrastructure.
