  • System and method for providing radio frequency conditions for testing wireless communications equipment
    Patent number: 6766164
    Abstract: An apparatus and a method for recreating radio frequency (RF) conditions of a cellular network extracts significant RF effects from field test data, and recreates variable RF attenuation using a multi-channel attenuator. A field data processor converts the field test data to time-varying attenuator control values for each channel of the multi-channel attenuator. Accordingly, a mobile in the lab which is connected to the multi-channel attenuator sees the same carrier and interference levels that were observed in the field environment, allowing cellular communication equipment testing without repeated field testing.
