HD Voice offers higher voice quality for networks and devices, like the iPhone 5, that can support it. T-mobile has already announced its own plans to deploy the technology when it begins selling iPhone 5s later in the month. Sprint also has plans for the higher resolution mobile audio.
AT&T today announced its own support for HD Voice, with senior VP Kris Rinne telling group of technologists at the VentureBeat Mobile Summit that AT&T plans to roll out HD Voice support later this year, at the same time it starts running voice calling on its own LTE network.
