Anyone who knows abt GPRS planning and performance meterics.

i need to have some course about GPRS to my e-mail if possible email@example.com February 2007 at 18:22 #46671pixGuest
gprs planning is highly linked to the abis & ater & gb dimensionning. from a radio planning point of view, special care must be brought to frequency planning (direct impact of C/I on the throughput performances) and in case of EDGE, there is a decrease of TRX output power (different modulation).
Also, radio capacity must be re-dimension, to cater for aditionnal data traffic (marketing inputs)2nd March 2007 at 15:41 #46672patrickGuest
i need course about gprs and edge2nd March 2007 at 19:11 #46673PixGuest
no problem, you can hire me for a GSM, GPRS and EDGE training…2nd March 2007 at 19:52 #46674TufailGuest
can you out some more light on this topic.

which topic exactly ?

thanks for replying.
I wanna know more abt GPRS planning and dimensioning.
Wat r da performance constrains.
Thanks and regards

i need to know when you do drive test how to do calcul about some radio parameter to do a report for example -64 -69:75 PERCENT
-70 -79:80 PERCENT
HOW CAN DO THIS CALCUL.30th April 2007 at 10:28 #46678PixGuest
i don’t know if the “automatic kpi reports” will have this feature or not. Try it out.30th April 2007 at 10:29 #46679PixGuest
Otherwise you’ll have to export the TEMS logfile in text format, then open it with Excel, and perform the RXLEV sample distribution by using formula…30th April 2007 at 10:33 #46680PixGuest
part 3 : get an external tool..27th May 2007 at 05:56 #46681GerardGuest
Can anyone tell me about the effect of the feature DTM(Dual Transfer Mode) on the radio net work system.27th May 2007 at 08:03 #46682PixGuest
The DTM feature (alcatel b10) allows to send or receive packets while being already in a CS communication.
During a CS call, one user can get PDCHs while still keeping its CS timeslot. Of course, the GPRS performances are a little bit reduced (if the MS is originally a 3+2 then, during a CS call, it can only get 2+1 PDCHs).
It doesn’t require hardware changes in the BSS nor NSS, it is a very “soft” change in the network.

i have some about our network
sometime, i see silence and interruption i don’t know this origin, Rxlev and Rxqual ok but silence and interruption.
Receive signal level RSL can provoke this problem is -50dbm
