    Hey guys need a helpy hand

    My NW Band is 4.4 MHz’s & We have total 22 BCCH (ARFCN), What kind of planning we can do?
    In terms of mapping, erlangs per cell, MAIO.

    Hi Redneved,
    For 4.4 Mhz band use 4/12 frequency re-use pattern.
    Erlangs Standard are as follow:
    1 trx : 2.09 erl
    2 trx : 8.01 erl
    3 trx : 14.03 erl
    4 trx : 21.03 erl
    and follows…..
    It depends on ur initial trx planning…….considering facts such as:
    no. of subscriber,erlang per user offered(TRAI rule 40 mE but planner always use 25mE ).
    MAIO values
    0 6 3
    2 8 5
    4 1 7
    Condition HSN should remain the same for the cells.
    Its can also vary as per contract between OPERATOR and VENDOR organisation.

    well
    thats was handy ….

    If
    Projected Subs : eg 100000
    Projected Erlang per sub: (generally 30 mErl or .03 Erl)
    Area 100 Sq Km

    No. of TCh frequencies…Logical mapping of TRX….as per 1800 band
