From Wikipedia, the free encyclopedia
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]
History
The concept of PoC was introduced by U.S.
telecommunications
company
Hytera in 1987.
[13] The first commercial use of PoC radios was also started by the company in 2002.
[14]
In June 2005, the
Open Mobile Alliance rolled out an approved standard called "PoC 1.0".
[15] In April 2020, Hytera presented a PoC radio named PNC550, equipped with a 5-inch
touchscreen that supports full operation using gloves.
