During drive test with TEMS Investigation at some locations i got RxLevelsub = -125dBm and the signal color displayed on the map is BLUE. I can still hear the voice, Whatcloud be the reason??
Help please.3rd September 2009 at 12:27 #58644PixGuest
TEMS mobiles have a better sesitivity than typical MS, they can hear signals at -125dBm. While MS can “measure” only -110dBm.
Then, if there are very clean radio conditions (= very high C/I), then the MS is able to decode such low signals.

The thing is we have been doing routine Drive Test at these areas before and we didn’t find this -125dBm RxLevesub also it happen randomly.3rd September 2009 at 13:24 #58646PixGuest
Then perhaps the connection between PC and TEMS phone is loose ? When the cable is disconnected, the TEMS software shows -125dBm.
Long time I used TEMS, but I remember something like this used to happen (in the past…)3rd September 2009 at 15:17 #58647YangGuest
what could be the reason of blocking call setup process at very strong single strength; at -29 dBm was impossible to make a call! what could be the reason,

here pic show radio test -27dBm
go google search for trewmte.blogspot and search at that site for
i try put url here i think not like4th September 2009 at 02:02 #58649KBGuest
The dive test result Rx Level –125dBm cause came from condition as below
Channel Type = HR
Sub Channel Number = 0
MAIO = 0
HSN = 0
Problem above be fix by change HSN from 0 to 1-63.
no impact. 😉 just for your report.5th October 2009 at 06:31 #58650rf fanGuest
Try to set HSN 1 even if hopping is cyclic.
Which vendor ?6th October 2009 at 09:03 #58651mayGuest
thought that the MS normal are better sensitivity than TEMS, because at many times when i do drive test in area where the tems lose signal typical MS have low coverage and i think that this is logical to perferm good tests
tell me if i’m in error!!!6th October 2009 at 17:56 #58652PixGuest
You’re not in error 🙂 I would suspect that the TEMS during a drivetest is located in a weird place in the car (under the seat, or at least no into a vertical position nearby a window).
a “normal” MS is in a more favorable position.
Try to move the TEMS in your car (but keep watching other cars…), the results are spectacular.
(spectacular, compared to the boring uneventful typical drivetest…. zzzZZzzz)5th May 2012 at 06:46 #58653AghaGuest
i need ur attention.
can u tell me the difference b/w RACH Min Access Level and RACH Busy Threshold in Huawei?
i want to know that how differ these both parameter eith each other?
Thanks in advance!!
