    Hi all,
    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.

    Hi,

    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.

    Cheers,

    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.

    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…)

    Dears,
    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,

    regards

    The dive test result Rx Level โ€“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. ๐Ÿ˜‰ just for your report.

    Try to set HSN 1 even if hopping is cyclic.
    Which vendor ?

    Hi pix
    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!!!

    May,

    You’re not in error ๐Ÿ™‚ 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)
