Dear Pix, results are excellent! Our KPIs are within limits.
I’m going to set these parameters for the whole network.
Things are worse with drive-tests 🙁 – we’ve finished the first part (without TFO) and got MOS = 3,1 (not bad but also not very good). Of course, we were measuring in MS-to-MS mode 🙂 As for measuring voice quality I’m absolutely satisfied with our new tool – Agilent platform. It’s very flexible and reliable tool. And its huge advantage is that it stores recived audio samples – so it’s possible to listen to them after drive test to assess voice quality by yourself.
I hope that within a few days we’ll have the other part of results – MOS with TFO :)) I’m looking forward to it.
P.S. Yes, working on the field is really very interesting and creative :))
