PoC radio
Other name
PTToC radio
Type
PoC device
Core function
Push-to-talk[1]
Introduced by
Hytera
Communication mode
half-duplex
A PoC radio (short for push to talk over cellular radio[2]), also known as PTToC radio,[3] is an instant communication device that is based on the cellular network.[4] It is a radio device that incorporates push-to-talk technology into a cellular radio handset.[5] It allows users to communicate with one or more receivers instantly, [6] in a half-duplex mode.[7]
Although a PoC radio is a walkie-talkie-like device, [8] there are substantial differences between them.[9] Compared to the latter, the former has a wider range of channels, covers a wider area, and does not require a license to transmit.[9] In addition, a PoC radio supports advanced functions, such as, video calls, multimedia messages, GPS location tracking, and emergency notifications. [10]
PoC radios are widely used in the industries of private security, logistics, hospitality, and rescue. The representative manufacturers of such equipments include Hytera[11] and ToooAir.[12]
