Hi all…
can you tell me what must i do to optimize BTS on rural and boundary area….there are very high calldrop & low CSSR..for your attention, very big thanks to you…
Joe…
First of all i would suggest u to check the hardware….bcoz low CSSR is mainly due to the faulty hardware….may be TRX…may be duplexer…which also leads to huge call drops.For this u can chek the Alarms related to hardware.
secondly, which boundry r u talking about..is it a BSC boundry or INTERNATIONAL boundry.
Well u can check the frequency plan first, MAIO plan, HSN.Joe,
Your description is too broad, I wouldn’t even know where to start. If you want some help, you need to spend some time analyzing the QoS and giving us proper and detailed QoS indicators values.
Basically : interference, coverage, congestion, distance, type of traffic, location area, neighbors, etc.
hehehe….yes pix you are right…
my description is too broad, but finnaly i take some action for my BTS which on hilly terrain…
i do to be down tilt until 6 deg from 4 degwhy must i do this, actualy the reason is :
the cells on my BTS has high coverage (on hilly terrain), >60% traffic on TA > 8 km. & 3rd sector precisely on TRX-11 has low utilization compared to TRX-9 (each non BCCH TRX) so there are causes dropcall,TCH drop,SD drop are on high value…
so for the time being, i do that to keep the KPI for the BTS.
maybe you can give me another solution with that condition???
thank you for your sharing information….
i’ll wait for it…
