The RST Smartbridge® is an intelligent Cross Band Repeater Controller, using two standard radios (the Network “Gateway Radios”) to link two radio networks together. A call is set up between two radios; an Over received on the first radio is transmitted out on the second radio, and vice versa, thus making a Conventional fleet or subfleet bi-directionally compatible with a TETRA Talkgroup.

System standards covered are MPT1327, SmartZone, TETRA, P25, and LTR. Most intersystem combinations (e.g. TETRA to MPT1327) are readily provided as well, by simple programming changes only
