<p>A distributed radio system with multiple transceivers (Fig. 5) for simulcasting and selective processing of received signals. The system includes processing elements and radio frequency transmitter elements (RFU) interconnected by an Ethernet network. RFU are designated to be elements of a radio frequency simulcast set. The system utilizes few frequency channels, and transmits at low power levels thus casuses minimal interference with existing macrocellular environment. When signals transmitted are detected, the system selects a desired radio receiver signal for processing using a distributed processing technique that performs the selection process throughout several levels which may be synchronized. A selection time window is utillized for the selection process for upstream-received data traffic including a centralized data link layer. Transmissions are implemented by a twolevel multicast technique. The data transmission traffic is bundled (320). Selective management of the Ethernet switches (BCM) is performed.</p> |
