ELECTRIC FIELD STRENGTH MEASUREMENT SYSTEM IN CELLULAR MOBILE BODY TELEPHONE EXCHANGE SYSTEM

摘要

PURPOSE: To automatically measure the electric field intensity by allowing a portable base station and a stationary radio base station having a service area adjacent to a service area of the portable base station to automatically collect transmission reception electric field information. ;CONSTITUTION: When an operation start command is applied from an operation terminal equipment 13, a test use radio equipment 11 receives a radio wave sent fixedly from each of stationary radio base station transmitter-receivers 3B, 3C possessed by stationary radio base stations 1B, 1C having service areas B, C adjacent to a service area D of a portable radio base station 6 for a prescribed time interval only. Then a mobile radio base station controller 9 converts the intensity of the radio wave into transmission electric field information in response to the intensity of the radio wave received the test use radio equipment 11 and sends the intensity automatically to a mobile body telephone exchange 4 via a mobile radio approach link device 8 and an opposite radio approach link device 17. Then the test use radio equipment 11 sends a reception electric field radio wave for a prescribed time interval under the control of the mobile radio base station controller 9.;COPYRIGHT: (C)1993,JPO&Japio
