Patent ID: 7555293

Claim:
A test method for determining radio frequency (RF) path loss for a plurality of RF channels in a given RF frequency band, the test method comprising: providing an RF source for transmitting RF power values at a relatively fine granularity; providing an RF receiver for generating received signal strength indicator values (RSSI) at a relatively coarse granularity; determining RF path losses for selected RF channels based upon generated RSSI values of the RF receiver within the given RF frequency band by sweeping relatively coarse and relatively fine RF power values transmitted from the RF source; determining an RF path loss function based upon the RF path losses of the selected RF channels; and determining an RF path loss having the relatively fine granularity with a finer granularity than the relatively coarse granularity of the generated RSSI for at least one other channel within the given RF frequency band based upon the RF path loss function.
