A PoC radio (short for push to talk over cellular radio), also known as PTToC radio, is an instant communication device that is based on the cellular network. It is a radio device that incorporates push-to-talk technology into a cellular radio handset. It allows users to communicate with one or more receivers instantly, in a half-duplex mode.
Although a PoC radio is a walkie-talkie-like device, there are substantial differences between them. Compared to the latter, the former has a wider range of channels, covers a wider area, and does not require a license to transmit. In addition, a PoC radio supports advanced functions, such as, video calls, multimedia messages, GPS location tracking, and emergency notifications.
PoC radios are widely used in the industries of private security, logistics, hospitality, and rescue. The representative manufacturers of such equipments include Hytera and ToooAir. Mission-Critical PTToC (MCPTT) is also starting to be employed in sectors such as public safety, transportation, and utilities.
