What are 4g Poc Radios?
About 4G LTE PoC Radio | Radioworx UK
A 4G PoC radio (Push-to-Talk over Cellular) is a modern two-way radio that combines the instant, one-button communication of a traditional walkie-talkie with the unlimited coverage of a 4G mobile data network.
Instead of relying on local radio frequencies or expensive signal repeaters, a 4G PoC radio uses a SIM card to send voice data over existing cellular networks. As long as you have a mobile network or Wi-Fi signal, your team can communicate instantly—whether they are across the street or across the country or the world.
How 4G PoC Radios Work
-
The Hardware: The devices look and feels like a two-way radio, complete with a rugged design, long battery life, and a prominent Push-to-Talk (PTT) button.
-
The Connection: Inside the radio is a multi-network SIM card. When you press the PTT button, your voice is converted into data and sent over 4G/LTE or local Wi-Fi in clear digital audio quality.
-
The Reception: The voice streams instantly to one recipient or an entire fleet of radios simultaneously with no dialing required.
4G PoC Radio vs. Traditional Two-Way Radio
