    In EDGE/GPRS test:
    RLC throughput or Application throughput (FTP download)…which one should be higher?

    hi
    it’s very much depending on your formula, but usually rlc throughput is higher than the application throughput (the LLC headers + bits of RLC/MAC signalling + retransmissions….)

    however, the real throughputthat you should worry about is the application throughput : it shows what the subscriber is experiencing.

    thanks for the reply.
    In our drive test,RLC throughput is low (very low) in most of the area, but application throughput is very good in those area.
    Is it normal?

    Hi,

    It is impossible ! The application data is trasferred over RLC protocol… so :

    RLC throughput = Application throughput + RLC “signalling”

    (I say signalling, but as said earlier, it is a bit more than that)

    You can see that both throughput should be linked. Check your throughput over a bigger time average, don’t look at instantaneous throughput.

    Cheers,

    ksa,

    In any case application throughput can never be more than RLC. In ideal case it may be same as RLC but never same. You will have applicationlayer packet drops/retransmissions above the RLC so it will always be less.

    As you go up the stack throughput will reduce.

    in 3g drive test we experienced there was a very small RLC throughput (it almost didn’t existed)

    n 3g drive test we experienced there was a very small RLC throughput (it almost didn’t exist) and higher application throughput. How?

    In LTE, I am having low levels in the Throughput app, what situations could cause it?
