Measuring system of reception electric field level in mobile communication

Abstract

Abstract PURPOSE:To make unnecessary the receiver for electric field monitor, by adding a multichannel switching reception function to a communication channel transceiver equipped with a radio base station and using a receiver not used for communication as reception electric field level measurement. CONSTITUTION:When a mobile station in a service area 1 moves from radio zones A-C to other radio zones while being in communication state, the necessity of switching of radio lines to a radio base station 3 of the mobile station is caused. Accordingly, to monitor the transmission wave of the mobile station ahead it, with the instruction from a radio contrl station 4, the reception electric field level for the transmission waves from the mobile station is measured at a bundle, by using the multichannel switching reception function of transceivers in vacant, not used for communication, at the time point, among transceivers equipped with the radio base station 3.
