What is Radio Over IP?
Radio over IP (RoIP) is an expanded version of VoIP, transmitting the radio control signals such as PTT (Push to Talk) and COR (Carrier Operated Relay) in digital format in addition to the digital voice packets. With RoIP it is possible to offer end to end digital signaling from a handset to any other communications device in the world. RoIP technology eliminates the leased lines previously used to remotely control base stations by tones and, in a RoIP digital implementation there are no conversions from E&M (Ear & Mouth) to IP limiting the controls signals available or delaying the speed of signalling. Of course true end to end digital signalling and communications also facilitates end to end encryption for secure communications.
