PTT over Cellular (PoC) is a modern communication technology that combines the simplicity of push-to-talk with the wide coverage of cellular networks. Instead of relying only on traditional radio frequencies, users can instantly connect through 4G, 5G, or Wi-Fi, enabling real-time voice communication across cities, countries, or even globally. It supports group calling, location tracking, emergency alerts, and multimedia sharing, making it highly useful for transport, security, construction, logistics, and field operations where fast coordination and reliable communication are essential.
