A system and/or method for facilitating wireless communication in an area where it is difficult to transmit and receive signals may use a preexisting wired emergency communication infrastructure to transmit signals between elements of a radio repeater system. Optionally, the system may include synchronization of retransmissions. Analogue and/or digital signals and/or data may optionally be transferred over the preexisting network. Data and/or signals may optionally include audio and/or video signals, digital data, telemetry data, and/or synchronization data. The system may optionally include multiple wireless receivers and/or a voter to select a version of a signal from at least one of the receivers. A network for concurrent repeating of a direct mode simplex wireless signal may optionally include multiple receivers and/or a voter. The simplex network may optionally include a coloring circuit. The power of retransmission and/or the insulation between a receiver and a transmitter may optionally be adjusted.
