Abstract
A trunked radio system range extender extends the range of a trunked radio system by having a second repeater station monitor the control channel for the trunked radio system detect and decode control information and rebroadcast it on to a second control resource. Communications resources from the first trunked radio system are similarly mapped into a second set of communications resources for subsequent broadcast throughout an extended geographic range. The extending repeater station uses the control resource from the first repeater station.
