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] Mission-Critical PTToC (MCPTT) is also starting to be employed in sectors such as public safety, transportation, and utilities.[13]

History

[edit | edit source]

The concept of PoC was introduced by U.S. telecommunications company Nextel in 1987.[14] The first commercial use of PoC radios was also started by the company in 2002.[15]

In June 2005, the Open Mobile Alliance rolled out an approved standard called "PoC 1.0".[16] In April 2020, Hytera presented a PoC radio named PNC550, equipped with a 5-inch touchscreen that supports full operation using gloves.[17]
