    half rate : one subscriber is coded at a rate of about 6kb/s
    full rate, one subscriber is coded at a rate of about 12.2kb/s

    in half rate, one subscriber will use only half the capacity offered by 1 timeslot.

    Physically : the MS in HR mode is sending a burst only 1 out of 2 TDMA frames.

    Cheers,

    ajay,

    usually, it depends on the load of the cell (busy TCH / available TCH). If cell is loadaed, the new incoming call are setup in HR.

    that’s vendor dependent, so i can’t give you the parameter names.

    hello,

    it’s difficult to answer, because you don’t provide any detail ! so here are some questions, to help me help you 🙂

    could you please write down which indicators or which measurements are showing “degraded speech quality” ?
    what do you mean by HO zone ?
    what kind of hopping are you using ?
    what is the intersite distance ?
    what is the downtilt applied and the antenna height ?
    how many TRX/cell ?
    in terms of qos stats, do you notice anything ?

    cheers
