An automated method of assigning frequencies to sectors of a wireless telecommunications system for use during a drive test calculates a usage factor for each frequency that is assigned to the system to be tested. The usage factor for a particular frequency is equal to the number of sectors of the system to be tested to which the particular frequency is assigned. The method selects a sector and selects the frequency assigned to the selected sector with the smallest usage factor. The method keys up the selected frequency in the selected sector and keys down that frequency and the adjacent frequencies in each of the other sectors of the system to be tested. The method continues the foregoing sequence of steps until a unique frequency has been keyed up for each sector in the system to be tested.
