why iuse EDAP in telecom sector?
13th December 2009 at 19:19 #48203NAGuestHi All,
EDAP stands for EDGE Dynamic Allocation PoolIt’s main function is to allocate the data call over prescribed and defined Trxs which we define o both 1) the Abis allocation and 3) on the BSC end where we create the abis for a site
so for TSLs 28,29,30 we select for EDAP for eg and for Trx 1,2,5,6,9 and 10. it means that we are including Trx no 1,2,5,6,9 and 10 as Trx which will handle Data call means net services with total of 192Kbps speed at all.
thanks
27th April 2010 at 09:47 #48204NAGuestCan anyone please tell complete configuration of EDGE in BSC, or steps that are required to properly enable EDGE on UPPER BAND of site.
12th June 2010 at 08:54 #48205kalimGuestEDAP or GPRS speed
Here ur question ask something diff while ur intension of asking question is diff. actually u want to ask what is the bit rate of GPRS between MS and BTS means wht exactly we get the speed out of mobile when we use internet connection.
.
.
For EDAP speed the timeslot we r assigning is the actual speed like, we are using 3 timeframe so it’s ABIS speed will be 192Kbps, so this is the ABIS speed not the Um speed, Um speed is maximum of 230Kbps but the EDAP is only 192Kbps n is divided into the all users using GPRS connection at a time, so in average i get 10-20Kbps in practical at my Nokia 3110c Modem so u can also calculate this. one thing to remember that not go to the Modem speed which shows u the 460Kbps or 115 Kbps whatever.One thing to be noted that EDAP in ABIS allocation consumes 1 time frame of minimum n hence u can calculate the speed out of it.
we all know 1 timeframe’s speed is 64Kbps (that is 4 time slots)
n hence wht we use, if it is 2 time frame then EDAP’s speed will be 64*2=128Kbps
and similarily this goes on.perfect ans for Speed of EDAP
If someone ask in interview the same question, the proper answer is.It is the multiple of 64Kbps..
12th June 2010 at 10:18 #48206KJBGuestHi Na,
Steps to Enable EDAP in BSC.
Define DAP on reuired TRX during TRX creation.u k=can use ZERC,ZERM MML CMD1- GENA enable
2-Lock Sector
3-EGENA enalbe
4-Unlock sector.Thx
KJ24th June 2010 at 17:34 #48207NAGuestThanks KJB,
Make me understand GPRS and EDGE both are different technologies but i experienced that whlile using MS, I got somewhere E facilities n some of the cells giving G facilities. wht’s the cause of this? n wht r the technical diffirences….
24th June 2010 at 18:50 #48208PixGuestNA,
EDGE is only an new set of features that are implemented on top of GPRS.
So you are not using EDGE (this “EDGE” is just a concept), but you are using E-GPRS.E = EGPRS
G = GPRSG means that the area where you are in does not provide the new set of features. Probably because the sector covering your MS wasn’t upgrade with the new hardware.
The most important feature is the usage of a new radio modulation (8PSK), instead of GMSK, which vastly improves the bitrate.
Regards

next question going to arrive.
27th June 2010 at 05:56 #48210NAGuestIF there’s any option in NOKIA BTS to trace out how many data calls r running (Traffic Trace shows Only marking Call by yellow color but not clear is data or voice).
thanx
27th September 2010 at 20:02 #48211AbhijitGuestHiii Alll….Can any one tell me hw to reduce the EDAP Congestion???
7th October 2010 at 14:04 #48212Vikas SehrawatGuestHi Abhijit,1st check any h/w issue,PCU utilization,or just decrease the dynamic time slot n thn take the observation…
13th October 2010 at 15:43 #48213sunnyGuestnokia bts when we put abis… TCH TRX SIG and OMU why we put this and why we put kbps for each TRX….
