    Hi

    how we can identify between cross feeder and cross sectors during the analysis

    hello,

    cross sectors : coverage of sector 1 is found in place of sector 2, and vice versa

    cross feeders : within the same cell, some TRX have a good RXLEV, while other have a very poor RXLEV. Because the TX of some TRX are sent on wrong sectors.

    Thanks Pix
    but as you know for cross feeder u cant make DT analysis by TRX…… u are not able to check RXlevel for each TRX on the cell

    TS,

    well, i used to do that. It’s no easy, but it’s possible if you’re patient 🙂

    not necessarily. I do it on the spot : i stop in one place, look at rxlev on bcch. That’ll be my reference. Theni make a callsetup on each TRX, and see what is the RXLEV on each TRX (without power control DL)

    if you have hard time putting the call on some trx, you can use the preference parameter to “prioritize” a TRX. Ask the OMCR engineer to change this parameter while you’re doing the tests.

    Pix is right, CROSS SECTORS is when the coverage of Sector 1 serving in Sector 2 or VV and for the Cross Feeders: you can check it much better if you do drivetest within a same cell the sector 1 and 2 or Vice Versa transmit on it.
