PoC Portable Radios

Push-to-talk over cellular radios — they use 4G and WiFi instead of a licensed radio channel, so two users have the same instant push-to-talk anywhere either of them has mobile coverage.

No licence, no repeater, no coverage survey. The trade is that you depend on the mobile network, which makes them ideal for fleets spread across a country and wrong for a tunnel or a remote site.
