Re: ATT is way ahead Do you know what effects codecs, compression, half-rate/full-rate, etc.. can have? How about what companies do when they have very limited spectrum in a given area? Or when they have tower congestion? The building-penetration abilities of the various frequency bands? It doesn't look like it.
The GSM/CDMA debate is pointless unless you take into account the countless differences that also contribute to call quality (or lack thereof).
You know, like how VZW is mostly 850mhz, while Sprint and TMO are 1900mhz, and ATT is a mix of both. Or how ATT uses a half-rate voice codec while TMO uses a full-rate voice codec. Or that TMO and Sprint typically have more towers (thanks to their 1900mhz usage) in urban areas than ATT and VZW do.
Frequency bands and codecs have far more to do with signal quality, nationwide coverage, and call quality than GSM/CDMA does. You'll see this when LTE rolls out. Everyone will use LTE, but you'll still notice substantial network differences due to codecs, frequency bands, and tower buildout.
