Supporting instant push-to-talk voice communications and VoIP telephone connectivity as well as open-standards applications support, the Simoco Xd digital base station is more than just a radio repeater. Each SDB670 forms the bridge between groups of radios and extends this to the world of IP.
The SDB670 builds on the highly successful and widely deployed Xfin blade, combining RF elements and control intelligence in one box for a unique architecture that has been proven in systems from a single base station to many hundreds.
