Does anybody know how to check the correctness of sector antennas/trx connection?
Probably there was incorrect connections in two sectors – 2 and 3. By means of TEMS drive test? Switch of/in sectors …
Antenna is a cross polarized with two feeders.
The procedure is to lock each of the TRX one by one, in turn, and perform a call setup on each TRX of each sector. You will see if there is a difference in RXLEV among the several TRXs within the same sector.
If there is a big difference : the TRX is actually belonging to another sector…
