    Hi friends,
    what is the description of sector?


    A sector is a “direction”. Usually, one sector = one cell.

    In one BTS, you can have 3 cells, each covering one direction. So this BTS has 3 sectors.

    In case of multiband network, you can have 2 cells per sector : 1 cell GSM900 and 1 cell DCS1800, both covering the same direction.

    A sector has no “logical” existence in the OMC-R.


    thank you so much Pix,
    before I thought each cell usually contain 3 sector. now i see they are the same.

    So in each BSS, I can have 3 cells.


    Hi John,

    Be careful on the words you use 🙂 BSS is the whole system, from TC to BTS. One BSS is your whole “radio” network.

    In one BTS, you can have one cell, up to six or eight cells. Usually, in standard configuration, a BTS carries 3 cells of the same band, or 6 cells (3 cells GSM900 and 3 cells DCS1800).

    In one cell, there is a certain amount of TRE’s (transceiver equipment). Each TRE can carry (in average) 1 TS for signalling and 7 TS for traffic (packet or voice). On 1 of those cell’s TRE, there is one timeslot dedicated for broadcasting (BCCH).



    many thanks Pix,
