PoC Frequently Asked Questions...
What is Push-to-Talk Over Cellular?
PoC stands for Push-to-Talk Over Cellular; a communication system that enables instant voice communication using mobile data networks such as 4G, 5G, and Wi-Fi. Unlike traditional two way radios that rely on local frequencies or repeaters, PoC radios operate over the internet, offering nationwide or even global coverage with zero infrastructure required.
You get all the familiarity of a push-to-talk radio, with the modern functionality and coverage of a smartphone.
Do PoC radios require a licence?
No. One of the biggest advantages of PoC radios is that they do not require a radio licence to operate. Since they work over cellular networks or Wi-Fi, you bypass the need for OFCOM licensing or frequency coordination, saving time and cost.
How Far do PoC Radios Work?
There’s virtually no distance limitation as long as both devices have access to 4G, 5G, or Wi-Fi, they can communicate. This makes PoC radios ideal for:
Multi-site businesses
Fleet management
Remote staff
Cross-country teams
Coverage is as wide as your mobile network allows and most systems have fallback options like Wi-Fi if the mobile signal is weak.
What features can I expect with PoC?
PoC radios are more than just voice devices. Depending on the model and platform, you’ll get access to:
Group & private calling
GPS tracking
Text & multimedia messaging
Encrypted communication
Cloud-based dispatch & management
Smartphone-like apps (on Android models)
Emergency alerts with location
What devices support PoC
