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.
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 comprising:
Apparatus 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 apparatus comprising a test processor, which is adapted to receive levels of the signals measured 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, and which is adapted to analyze the levels and the frequency channels of the measured signals so as to classify the measured signals at each of the locations according to the antennas transmitting the signals.
A computer software product 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 product comprising a computer readable medium, in which program instructions are stored, which instructions, when read by a computer, cause the computer to receive levels of the signals measured 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, and further cause the computer to analyze the levels and the frequency channels of the measured signals so as to classify the measured signals at each of the locations according to the antennas transmitting the signals.
