Abstract
A base station is configured to facilitate its rapid deployment to provide trunked radio communication system. The base station includes a receiving section and a transmitting section functioning as a repeater operating on a single trunked duplex channel. The base station also includes another receiving section for interrogating the presence of pre-existing RF energy in a given geographic area before allowing the base station to become active. This prevents a newly introduced deployable base station from interfering with pre-existing deployable or fixed base stations.
