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 ?
you can see the raw bitrates for different EDGE coding modes (PDCH
coding scheme will vary depending on RF layer performance):

so it's 8.8 kbit/second / slot to 59 kbit/second /slot
For pure GPRS it's 8 kbit/second / slot to 20 kbit/second / slot
