Abstract

Multi-site trunked radio systems that use half duplex radios can not change from one site to another (or even know when they need to change sites) when the subscriber radio is transmitting. This invention will ena- ble a trunking half duplex subscriber radio, traveling from site to site in a multi-site trunking radio system, to change site afIXation without loss of communications. Chang- ing site affiliation can include when the subscriber radio is transmitting or receiving. This invention uses a GPS (Global Positioning System) receiver and a portable corn- puter connected to a subscriber radio.
