    In a busy hour :
    According to Erlang B table, 7timeslot (1 trx in combined mode) with 2% GOS =3 Erlang(in 1hour).
    But according to Erlang Definition it should be 7Erlang (in 1hour).
    So, Where is that remaining (7-3)= 4 Erlang??

    hi,

    the system capacity is 3erl@2%…

    it means that when 3 erlangs are sent into the system, there are 2% which will be rejected.

    If you send 7 erlangs, there will be about 50% of these 7 erlang which will be rejected.
    The reason is that only 7 simultaneous can be handled. And statistically, 50% of the incoming calls will arrive when all 7 TS are busy.
    And other times, only 2 or 3 TS are busy.
    This is all linked to the random arrival of calls.
    regards

    Hi Pix,
    Thanks for the answer.
    But still I am cunfused..

    But If, the TRX is totally free and 7calls arrived at a particular time, and the duration of each call is 1 hour.
    Then what will happen??
    It will 7 erlangs or as usual 2.94 Erlangs?

    malay,

    yes, those 7 calls that last one hour would be measured as 7 erlangs.

    —
    now, to go a bit further : you agree that 7 simultaneous calls of 1 hours will never happen !

    The erlang B table is actually telling you how “real” subscribers are going to behave, and what is the capacity of your system, relatively to this chaotic world.

    Cheers

    narendra,

    one trx contains 8 timeslots, and let’s say 6 of them are TCH.
    in such case, in maximum usage, a TRX could carry up to 6 erlangs.

    So 2.9 erlangs is possible.

    regards

    @RAKESH BHATIA,
    if you are dealing with data capacity, it’s not similar with voice capacity forecast, talking about data/PS will be end up in end user perception ( maximum throuhgput ) target, no matter technology you use, GSM, WCDMA, LTE, you name it.

    But be carefull when you move further into throughput discussion, try to have deeper understanding about RLC/LLC throughput or even network throughput by using counter in measurement
