1. A method for simultaneously performing a radio frequency evaluation survey of multiple base station site candidates, the method comprising: i) a plurality of stationary receiver units, wherein at least one stationary receiver unit being located at each base station candidate site; ii) a mobile test transmit unit located in a test vehicle; iii) transmitting one or more radio test signals from said mobile test unit; iv) recording a time stamp for each location along the drive route 900 of said test vehicle, the power of said transmitted radio signals, and geographical coordinates of each location; v) receiving said radio test signals at each of said stationary test receivers, measuring the signal strength of said radio test signals, and recording said signal strength of these measurements along with a time stamp for each measurement; vi) correlating said recorded signal strength measurements with the location of the mobile test unit for each recorded corresponding time stamp; vii) calculating the path loss between the location of each base station candidate site, and each location along the drive route 900 visited by said test vehicle during the test survey as the ratio of transmitted and received test signals for the timestamp corresponding to said location; whereby said path loss information for said base station candidate sites is obtained with a single drive of said test vehicle throughout the desired test area.
