I found Path Balance = 0 (in one RTF at motorola BTS).
What is this mean?
or its an error in statistics?16th April 2007 at 18:01 #47045PixGuest
How is calculated your path balance ? Normally if path balance = 0, it means your cell is perfectly balanced 🙂 so it’s all good.

But its not good cell.
We calculate Path Balance as the following:
path balance = path loss + 110
path loss = uplink path loss – downlink path loss
uplink path loss = actual MS txpower – rxlev_ul(in BTS)
downlink path loss = actual BTS txpower – rxlev_dl(in MS)
so if the loss =0 that means Path Balance = 110 ~(V.good cell)17th April 2007 at 08:05 #47047PixGuest
Ok, that’s a weird computation… So it means the mobiles in this cell are receiving a very very weak RXLEV DL. Which means that your cell is sending a very weak signal.
I suspect a transmission power very low. Swap your TRE and your ANC with new equipments, and check if the TX power is back.17th April 2007 at 18:20 #47048ameerGuest
We know that if this RTF is defined as BCCH and SDCCH AND switchable (SDCCH or TCH) the path balance = 0 .
with other words path balance is calculated only on TCH channel
is this correct? please I want more details about this.17th April 2007 at 22:25 #47049PixGuest
Path balance can also be computed on a SDCCH timeslot as well as on a TCH timeslot. but i’m not sure i understand your question, actually.22nd May 2007 at 11:29 #47050NarChaiGuest
Motorola no TRE and ANC hardware just kiding:)3rd June 2007 at 15:12 #47051ArpanGuest
Zero path Balance in Motorola means
ur DRI is not Transmitting…
Firstly give it Hard Reset, if path
balance is not OK then replace the DRI….
Also check if the other DRI on the
same feeder is having good path
balance; if not then check the feeder…

a DRI has 0 path balance if its either not transmitting or not carrying calls, in either ways reset the radio or better swap it and try again
if the same RTF still does not carry calls or has path balance value of 0 and the cell has low traffic; then maybe that RTF has a higher interference value or it has higher channel allocation priority19th June 2008 at 12:22 #47053HuNiGuest
Is PB for this RTF=0 in all 48 intervals?
