What is PoC Radio?

Push-to-Talk Over Cellular (PoC) radios combine the simplicity of a walkie-talkie with the coverage of modern cellular networks. Instead of relying on repeaters or limited-range frequencies, PoC radios connect over 4G/LTE service, giving you nationwide communication at the press of a button.

Why PoC?

Unlimited Range: As long as you have LTE coverage, you can connect instantly—whether you’re across town, across the country, or out of America.

Instant Connection: One button push. No dialing, no ringing, no waiting.

Group Communication: Talk with one person, a team, or your entire network all at once.

No FCC License Required: PoC runs on cellular networks, not restricted radio frequencies.

Scalable: From a single radio to hundreds, PoC grows with your needs.
