you can increase the bitrate by adding more PDCH on other timeslots.
You will lose those for voice, though. The nanoBTS is capable of
dynamic TCH/F + PDCH switching, but we don't support that in OpenBSC
yet.
ok understand, TCH/F + PDCH repartitions based on your
how could i calcultate the theorical layer2/ip troughput available for one PDCH
and correlate it to the troughput measured from the MS to an external IP ?
Should add
more cells (bts?) to add more channels ?
More BTSs (stand-alone) is not improving capacity, but you can increase
coverage by putting them at different locations.
If you stack BTSs (multi-TRX), you can e.g. run the firs TRX with 7*PDCH
and run the second TRX with TCH. This way you have maximum GPRS/EDGE
bitrate, plus full set of voice channels.
Excellent, i will work in this direction and let you know.
My best regards,
Xavier.
Regards,
Harald
