Gsm base station test unit

摘要

To enable testing of a lightly loaded, remote base stations 2, a mobile phone 3 located within the cell is programmed to dial a test number via the PSTN. The test number generates an audio signal, e.g. a fixed tone which is transmitted to the mobile phone. A test unit 4 is connected to the mobile phone and initiates the test program and monitors receipt of the audio signal.
