A method of adapting the Orthogonal Channel Noise Source (OCNS) for optimization and acceptance testing of a CDMA based wireless network under load conditions is disclosed. According to an embodiment of the invention, a test loading level (for example, 80%) and performance requirements are established for a plurality of Base-station Transceiver Subsystems (BTS). The subsystems then transmit any required overhead power plus sufficient OCNS power such that the total output level of the BTS power amplifier is at the selected test level (e.g. 80%). As a mobile unit moves within range of a BTS and requests access, the unit's power requirement is determined based on the requested data rate. The OCNS power level of the new BTS is then adjusted or lowered by an amount equal to the detected power requirements to allow access to the mobile unit. The BTS then establishes a communication link with the mobile unit. Thus, the total power output of the tower under test is maintained at a pre-selected level such as for example 80%.
