Abstract
A method and apparatus testing a mobile communications system includes a test control system, real mobile units, and an attenuator matrix controllable by the test control system to vary strengths of signals transmitted by the mobile units for receipt by the mobile communications system. By varying the attenuation of the signals communicated between the mobile units and the mobile communications system, the mobile units may be made to appear to be moving to the mobile communications system. Movement patterns of the mobile units may be stored in the test control system to control attenuation in the attenuator matrix.
