Propogation Delay for overshooting cells

[jamalll2000]

Hi friends you can find the overshooting cells by calculating the Propagation Delay. Try to plot this graph.

what's do you mean? yes absolutely we can using PropDelay to approximate overshooting cell using NASTAR tools then combining with SHO overhead to make complete analyze (ideal value : 30%-40%)

Hi jamal

Which plot are you talking for??

How precise and accurate is propagation delay? What do you mean by combining SHO overhead?

Please clarify as I have been pondering about this topic for awhile now.

Thanks!

if your equipment is huawei you can use this counter : VS.LCS.OutCellCover.CellIdRtt

dear when you have overshooting cells you will have bad quality & high SHO Overhead .

* propagation delay in 3G = TA in 2G (you can get it in drive test by using nastar)
* soft handover overhead = # of times where UE was in SHO state(more than one radio link)/# of times where UE was in connected mode(also can be calculated in DT)

in 3G overshooting means both bad quality & resource wasting (not like 2G) . because when UE can decode the serving cell & the overshooting one , it will enter SHO state even though it's not in SHO area .

hope it's useful

how u can get propagation delay for drive test from Nastar...?! not possible at all!

So if my site overshooting;however has SHO overhead of 30% and SSHO of 5%; should I leave it alone?

no you should fix the overshooting . because overshooting increases ur rssi ==> bad Ec/No .

sorry ... my mistake
