    Hi Rich!
    It is very simple:)
    If you have a channel with 64 kbit/s (230400 kbit/h)throughput and your information source bitrate is 230400 kbit/h, then you can say that your source is creating load with 1 Erl intensity on that channel. Accordingly – 230400/2 = 0.5 Erl, 230400/4=0.25 Erl for this case.

    Hi Pan,

    I thought 1 Erl = 64kbps and not 230400kbph

    Hi, Dennis Tham !
    It is dependent for what time period you are averaged your load. Usually in telecommunications it is one hour.

    Hi professionals,
    the WCDMA system is a little different from GSM and others. In GSM, when you used to have problems with traffic demand, you really need to imply more TRXs. But in WCDMA the Transport network is very important and must be primarily verified. Suppose you have a growing traffic that is reaching the transmission BW, then the chosen QoS will be in charge of reducing this BW in order to keep loss and delay requirements. Then, my answer is that you must verify your system before start increasing HW.

    What is the capacity for a BTS in erlang for a GSM and a CDMA business seperately??

    Hi Pan,

    Thanks for your insight. Yeah, I understand now, 64kbps = 64 x 60 x 60 kbph = 230400 kbph….

    Another question, do we actually consider the uplink or the downlink when we convert the Erl to kbps?

    dennis,

    usually, we consider only the downlink, because it is the direction in which there is the most traffic.

    so f the capacity is enough in DL, since it is symmetrical in DL and UL (capacity DL = capacity UL), it is plenty enough to carry the UL traffic.

    hi
    how we can calculate IP bandwidth in kbps for 1 Erlang of voice traffic?

    Hi,Singh.
    It depends on the coding you choose. Standart voice channel is using PCM(Pulse code modulation) with result 64 Kbps. But with other modulations you can lower the speed to 8-9 Kbps.
