Abstract
Testing a CDMA cellular communication system involves placing stationary load box test units about a selected cell and transmitting predetermined signals from the test units. The signals include voice signals or audio test sequences, such that the transmissions simulate traffic loading in the cell. The effective radiated power from the stationary test units is varied in a predetermined manner to simulate fading, multi-path, and motion. A mobile test unit traverses the cell along a predetermined path. The mobile test unit makes, a CDMA telephone call to at least one of the stationary test units during transit. The mobile test unit includes a data recorder, which records test data regarding the call(s), including a recording of the voice or specialized audio test sequences. One or more of the stationary test units that receives a call from the mobile unlit also records pertinent data regarding the test call.
