The AOA Calibration Test will only run on AOA WLS sites. The test automatically determines if a

WLS is AOA capable and which sectors are configured for AOA. It also determines the frequency

band(s) being filtered by the RFDU from the BPU initialization file. On each AOA sector, the

calibration signal level is measured on all four channels in the cellular A and B frequency bands

and in the PCS band.

To pass the test, the received signal level must be greater than a minimum threshold of -70 dBm

and the signal power of channels 2 through 4 must be within 5dB of channel 1, the reference

channel. The test is only required to pass in the frequency bands being passed by the RFDU.

Note: The AOA Calibration test results are only valid after all AOA antenna cables are

connected to the WLS and RFDU/antenna switch hardware.

An example of the test display for a WLS configured with one AOA sector and a PCS RFDU is

shown below.
