AT&T also plans to embrace over-the-top services

About a week ago, T-Mobile announced that it would finally be brining the iPhone 5 to its wireless network. The company also made plans to bring HD Voice service to its LTE network.

Not to be outdone, AT&T has now announced that it will also add HD Voice service later this year. HD Voice provides users with higher quality (High Definition) audio, and requires support from the calling network and the devices making the call. That means that the network, your device, and the device of the person you're calling all have to support HD Voice capability.

AT&T senior VP Kris Rinne said, "HD Voice is part of our voice over LTE strategy."

Rinne also said that AT&T would be working on LTE Advanced service as well. LTE Advanced is designed to reduce interference and bond traffic from multiple frequencies together.

Disagree. Anything to improve the audio quality on a phone call is welcome, and there are noticeable differences in voice quality across different types of phones.

Our IP based conference lines at work have decent quality, but you can generally tell when the other end is dialing in from a land line or from a cell phone.

I refuse to call my girlfriend using her Google Voice number, as it's significantly worse than dialing her regular cell number - probably something to do with the compression that has to be applied over the network here in NYC, but whatever the reason, it's worse than regular T-Mobile.
