PoC Radios Explained: Push-to-Talk over Cellular

Push-to-talk over Cellular (PoC) sends voice through a mobile data service and a hosted talk-group platform. It gives users a radio-style interface while relying on the selected network, service arrangement and device.

How PoC differs from conventional radio

A conventional Business Radio system uses radio frequencies and the conditions of its Ofcom licence. PoC uses cellular data, so its operation depends on network availability, the service platform and the device configuration. Coverage extends only to the places served by the chosen network and platform; it is not guaranteed in every location.

Compare the three PoC devices

The Hytera P50, P50 Pro and PNC550 are different PoC devices. PNC550 is a five-inch PoC terminal with a dedicated PTT button, dual Nano-SIM standby and Wi-Fi; cellular use needs a suitable SIM and data service, while the PoC application and account are chosen for the deployment. The P50 Pro's additional platform or device functions must not be assumed for the P50.

The PNC550 equipment offer includes the terminal and removable battery, without a PoC subscription. Arrange a compatible PoC application and account separately; cellular operation also requires a suitable SIM and data service.

PNC550 charges through a USB Type-C data cable connected to a compatible power adapter, suitable USB power source or computer USB port. A desktop radio cradle is not required for that charging route. Add any required cable and power adapter to the quotation.

Where PoC may suit

PoC can be useful when users need push-to-talk across locations and the chosen mobile service supports the places where they work. It may be unsuitable where network coverage is unavailable, where the operating model requires independent local radio, or where the service terms do not match the project.

PoC, PMR446 or Business Radio?

  • PMR446: licence-exempt only within its current equipment and use conditions; it is a hand-portable local option.
  • Business Radio: a licensed radio system with frequencies, equipment and coverage arrangements matched to the licence.
  • PoC: a cellular data and platform service whose operation depends on network and service conditions.

Compare the licensing decision guide and PMR446 guide before selecting the route. Compare the exact device, service and network arrangement for the PoC deployment.
