What is PoC (Push to Talk over Cellular)?

Push-to-Talk over Cellular (PoC) is a modern communication technology that enables instant voice communication over mobile networks like 4G, 5G, and Wi-Fi. Unlike traditional two-way radios, which rely on dedicated frequencies and have limited range, PoC works anywhere there is network coverage, allowing teams to stay connected across cities, countries, or even globally.

PoC offers several advantages over conventional radio systems. It eliminates the need for costly radio infrastructure, reduces maintenance efforts, and allows organizations to scale their communication effortlessly. Users can communicate one-on-one or in groups with the push of a button, just like a walkie-talkie, but with superior voice clarity and additional features like location tracking, emergency alerts, and multimedia messaging. Since PoC runs on standard mobile devices, it provides greater flexibility, enabling users to switch between smartphones, tablets, rugged devices, and even desktop applications, ensuring seamless connectivity across industries like security, logistics, construction, and public safety.
