in half rate two subscriber use one timeslot can you exlain this
thank’s in advance14th July 2009 at 11:36 #57913PixGuest
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.

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.16th July 2009 at 09:24 #57916ajayGuest

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 ?
