A method for analyzing service in a wireless communication network, which
includes multiple antennas, which are assigned to transmit signals over
the air to mobile units on respective sets of one or more frequency
channels, such that at least two of the antennas transmit the signals on
a common frequency channel. The method includes recording levels of the
signals received at multiple locations within a service area of the
network, while the antennas are transmitting the signals on the
respective sets of frequency channels, including simultaneous
transmission by the at least two of the antennas on the common frequency
channel. The recorded levels and the frequency channels of the received
signals are analyzed so as to classify the received signals at each of
the locations according to the antennas transmitting the signals.
