FOR Rahul of NR
Data rate for EDGE TRX depends on EDAP.this is dynamic Abis pool for data tranfer.
Generally what we do is we define EDAP for ETRX of each sector that is shared by all sector.Means if my site has configuration of 4+4+4,and 1st TRX of each sector is ETRX+BCCH one.then 1,5,9 will be ETRX for each sector.we’ll define EDAP of required bandwidth n x64 Kbps.This will be shared by all the sectors and GPRS timeslots will be defined normally.That means if ur phone supports and nobody else is using data services in that sector then u’ll have complete access on available bandwidth whatever is defined in EDAP.it could be in multiples of 64kbps.DAP or EDAP is EDGE DYNAMIC Abis POOL.GENERALLY WHAT WE DO WE DEFINE FIXED TIMESLOTS FOR EACH TRX IN Abis BUT IN DAP WE DEFINE TIMESLOT(S) NOT FOR A SINGLE TRX BUT FOR A GROUP OF TRX SAY 1ST TRX OF EACH SECTOR THEN THIS TIMESLOT WILL BE SHARED BY ALL THE DEFINED TRX OF EACH SECTOR DEPENDING UPON THE USAGE IN EACH SECTOR.IF NOBODY IN 2ND AND 3RD SECTOR IS USING THE DATA SERVICES(EDGE) THEN THIS DAP WILL BE ASSIGNED TO THE USER OF FIRST SECTOR COMPLETELY IF HIS PHONE SUPPORTS SUCH CAPACITY.
