MOS TESTING Tutorial(Tems)

[sonerss]

I agree to fotondiamond. SQI depents on DL Quality. But MOS is depents on DL/UL. And MOS values gives us Radio, Transmission and Core Network layer performance. Maybe Radio Layer performance is good but Transmission Layer performance is bad so MOS values get bad...

As I know SQI only measure Downlink Quality not Uplink.

MOS measure both Uplink & Downloink.

yes this is correct.

better we use MOS

[binladen]

To test MOS we often use Nemo equipment to drive test.

Yep
We take MOS values by NEMO & SwissQual too

[MRO3]

what are the equipment names and is there any manual for them?

Find below doc about MOS evaluation by SwissQual.

Their Video Quality algorithm is also approved and referred for
testing Video Tests, Streaming Tests etc as well.

No pass ..

But pls add rep and thanks if you like ...

Mean Opinion Score (MOS)

Mean Opinion Score (MOS) scale is frequently used. The MOS scale is described in ITU recommendation P.800. In a MOS test the listener grades each speech sample (normally five to eight seconds in length) by assigning it to one of the following categories:

MOS Meaning
5 Excellent
4 Good
3 Fair
2 Poor
1 Bad

what is MOS? something like amos/moshell??
