  • Patent number: 5974081
    Abstract: A wayside station communicates with a plurality of mobile stations over a wireless communication network. In one embodiment, a wayside station includes a transceiver configured to receive an inbound signal from a mobile station and to transmit an outbound signal to the mobile station. The transceiver has a first switch that is configured to selectively deliver the inbound signal to one of a first band pass filter (BPF) and a second BPF. A second switch is coupled to the first BPF and to the second BPF, and configured to selectively receive the inbound signal from one of the first BPF and the second BPF. A detector is coupled to the second switch and configured to detect the inbound signal, to convert the inbound signal to inbound data and to transfer the inbound data to a processor. The processor decodes the inbound data and processes the data.
