Push to Talk Wide Area Radio System

PoC is Push-To-Talk over Cellular (SIM). We all know 2-way radio systems (DMR/PMR), have been around for many years successfully connecting many workers across many businesses. These 2-way radio systems require dedicated infrastructure and radio licenses. PoC uses any cellular networks, Wi-Fi or Internet, so there is no need for any infrastructure or radio licenses. Now 4G/LTE cellular network coverage reaches almost every corner of the UK with 5G on the way, migration to PoC is rapidly replacing the conventional 2-way radio market, and as there are no additional infrastructure costs or radio licenses the ROI is greatly increased.
