What Is Push-to-Talk Over Cellular - Chat-Com Two way radio

Modern Communications, Anywhere You Go

Push-to-Talk over Cellular (PoC) is revolutionising the way teams communicate. PoC uses mobile data networks (4G) to deliver instantaneous voice communication over virtually unlimited distances, unlike traditional two-way radios that work on short-range radio frequencies or infrastructure through antenna installations.

Whether you’re managing a large-scale cycling event, coordinating field teams nationwide, or need comms across a broad geographic area, PoC radios provide a flexible and robust solution.

What Is PoC and How Does It Work?

At its core, Push-to-Talk over Cellular transforms a mobile device or dedicated radio into a walkie-talkie that works over the internet. Here’s how it works:

Data Network, Not Radio Waves: Instead of using UHF/VHF frequencies, PoC radios connect to mobile data networks using SIM cards—just like smartphones.
Group and One-to-One Calling: With the press of a button, users can talk to the whole team or select individuals instantly.
Nationwide Coverage: As long as the radio has a signal from a mobile network, it can connect. This makes PoC ideal for large-scale or mobile operations.

Using Data Roaming SIMs in PoC Radios

PoC radios come equipped with multi-network roaming SIM cards, which are essential for maintaining reliable connectivity:

Automatic Network Switching: The SIM can connect to the strongest available mobile network (O2, EE, Vodafone, etc.) in any location.
Uninterrupted Coverage: This is especially important in remote or rural areas where one network may have better coverage than others.

This technology is particularly powerful when paired with the right devices—dedicated PoC radios that are rugged, lightweight, and purpose-built for instant team comms.

Real-World Example: Girls That Ride Bikes

A perfect example of PoC in action is Chat-Com’s collaboration with Girls That Ride Bikes, who used the radios during their Chase the Sun endurance cycling event.

With riders stretching across miles of road and support vehicles leapfrogging between checkpoints to avoid the cycle route, maintaining communication was crucial for safety, logistics, and coordination:

Chase vehicles could keep in constant contact and advise on progress.
Riders’ welfare was monitored in real-time.
Hands-free comms riders had earpieces that allowed them to communicate without holding a phone or radio device while on the move.

The radios delivered wide-area, instant voice updates—something traditional walkie-talkies or mobile phones couldn’t do efficiently without dropped calls or range issues.
