can any body help me to clear what is path blance in motorola and what the value -110 and -105 means in path balance report in motorola10th November 2009 at 10:50 #59515Main ZanduGuest
Path balance terminology is global term & not vendor Restricted
IN SIMPLE LANGUAGE
“The link balance between UL & DL on Um interface”
Path Balance= Path loss+ 110
path loss = UL Path Loss-DL Path Loss
(1)UL Path loss =Actual MS TX power- Rxlev_UL
(2)DL Path Loss =Actual BTS TX Power- Rx Lev_DL
If PB report pegs 120 or more then problem with RX PATH having high UL Path Loss
IF PB report pegs 100 or less then problem with TX PATH having high DL Path Loss
Path loss of + or – 6 is OK which ranges to -104 to -116 dbm
NOW ANSWER TO YOUR QUESTION “what the value -110 and -105 means in path balance report in motorola” is
-110 means very good balanced radio path having no path loss
-105 means slighly more DL path loss with TX path needs to be chk.
Please revert for any more query.

Isn’t the path balance criteria a vendor dependent parameter?18th November 2009 at 12:19 #59518BijoyGuest
Path Balance is vendor independent for sure.
What varies is the Network element losses/sensitivity like combiner loss,antenna gain,TMA,duplexer loss,frequency band in use,etc etc and so the path imbalance tolerance limit
