    Can someone tel me the difference between SQI(speech quality index) and MOS(Mean Opinion Score) and how to link the 2 parameters. I have bought the NEMO for drive test but it cannot give me the SQI, and my boss need the SQI to check the quality of the Network.
    Help, please!

    Hi Optim,

    I wonder which MOS values you are talking about and where did you get this table?

    As you know there are P862.1, SQUAD LQ, SQUAD NS… I want to know this table calculated for which algorithm.

    If you enlighten me I’ll be glad.

    Thanks Optim,

    Sorry for the delay, I was not connected since 2 days.

    Korgi, which MOS are you talking about. The one we are talking about is a call quality indicator.

    Very Best Regards,

    JCB

    Hi,

    Why there is 8 TS in 1 TRX?

    It is because of TDMA frame feature, GSM standard or any other reason…

    pls share….

    SQI and mos is same. Both measures speech quality.Values are diff..
    In NEMO go to parameter window then go properties and choose voice quality.

    Hey frds,..

    If my SQI value is 30 then what should be the Voice quality , is is 12.2 kbps or something else ? Can some one share me the SQI vs Kbps table.

    Thanks

    SQI is based on digital signal, MOS now is compare voice, actually, SQI is suit to test, but, in some countries, they make the product (audio card) for MOS testing, then they push operator test MOS, actually MOS testing is a lie

    Hi All,
    Which OSS KPI, KQI can reflect the Net Promotor Score (NPS) or MOS of the GSM, UMTS and LTE network.

    Thank You
