    Hi Sachin,

    It seems that you are going to attend some interview for ericsson related company.

    Pls remember be practical in Interviews.They may ask you some very down to earth questions also.
    Which demand your presense of mind.

    In Two TRX means TWO ARFCNs/GSM Freqs.

    One Freq is Equal to = 8 TS

    Tw Freqs so 16 Time Slot.

    One Timeslot for BCCH.
    One Timeslot for SDDCH*8.

    One Timeslot can Handle 8 SDCCH.

    So remaining 14 Can be used as TCHs.

    I heard that there is a combined methode.But Idle is the above 0ne.

    In the above set up at the same time you can do 8 Call attempts only.

    But Can serve 14 Calls easily.

    cross polarized Antenna the radiation is equal in either horizontal or vertical mode

    normal polarized antenna transmits only in vertical direction
    while there is a 15dB differnce if u keep it horizontal
