  • Radio telephone base station with a monitoring apparatus
    Patent number: 5857012
    Abstract: A base station for a radio telephone system includes a monitoring device for monitoring operation of the base station. The base station has two antennas, and two couplers for coupling the monitoring device respectively to first and second ones of the antennas. Thereby, test calls can be made between the base station and the monitoring device without the need for the monitoring device to have an antenna. Each of the coupling means is operative to enable selective transmission and reception of signals at the monitoring device via a respective one of the first and the second antennas.
