Analog two-way radios use analog signals to transmit and receive voice communications between two or more parties. Analog radios are also known as “walkie-talkies” and are commonly used in industries such as construction, public safety, and transportation.They are still widely used in certain industries due to their simplicity, reliability, and cost-effectiveness.We also supply two-way radio battery, charger, antenna of them.

Digital mobile radio (DMR) is a digital radio standard for voice and data transmission in non-public radio networks. It was created by the European Telecommunications Standards Institute (ETSI),and is designed to be low-cost and easy to use.

DMR was designed with three tiers. DMR tiers I (Unlicensed) and II (Conventional Licensed) were first published in 2005, and DMR III (Trunked version) was published in 2012, with manufacturers producing products within a few years of each publication.

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.
