Abstract
The present invention includes a system for testing the acoustical performance of a cellular communication system and includes a field unit such as a cellular phone that can both send and receive signals to and from a base station. The base station is connected to a testing computer via digital communication lines for transmitting the test data. The system prevents the signal between the base station and the testing computer from being transferred through an analog central office that may cause unknown noise to be inadvertently included within the signal and prevent accurate testing and calibration of the communication system. Audio messages may be sent from the field unit to the testing computer for testing, or the audio messages may originate at the testing computer and then sent to the field unit. The system further provides for results from the testing to be sent to a technician at the field unit to allow for evaluating and making any changes within the communication system.
