Sound quality and network
in [UK Mobile]
|
From: Scott on 1 Mar 2010 17:20 A question. I have recently transferred from Vodafone to O2, keeping the same phone. A friend says the sound quality is not as good - more distorted and too loud. I assumed all networks would operate to the same technical standards (or at least the 900 MHz ones would). So is there a difference between networks or is it more likely to be a different cause? Is the sound quality worse if you call from a mobile to a cordless phone since I assume both need to digitise the sound? Scott

I suppose the follow-up is to ask whether O2 is more prone to cutting the codec than Vodafone.

Does the whole network get cut during busy times or is it on a cell by cell basis? Is this a rare experience or does it happen every day at certain times? |
