Radio over Internet Protocol(IP) Gateway uses standard techniques to transfer the analog and digital signals used by Land Mobile Radio/Repeater Systems digitally over the IP (or Internet). In addition to voice, RoIP also transfers signals that are specific to LMR applications, such as PTT, COR Control lines or other Data Signals. It provides a secure wide area connectivity between Radio Systems at different locations. It supports all radio technologies (Analog, DMR and Digital Tetra Radios) operating over VHF and UHF Bands.
