AT&T has announced HD Voice is coming to AT&T this year. At the VentureBeat Mobile Summit in Sausalito, California, AT&T Senior Vice President of Network Technologies Kris Rinne said that HD Voice is a part of the company’s LTE strategy. HD Voice requires support from the network and the devices on each side of the call. AT&T’s HD Voice will be rolled out later this year as they start to route voice calling over the LTE network.
The news of AT&T’s HD Voice comes on the heels of T-Mobile’s HD Voice announcement. T-Mobile announced that they would offer HD Voice as they start selling the iPhone 5 later this month. Sprint rolled out their HD Voice service last year, but the iPhone 5 does not support that feature on their network.
HD Voice means that voice calls will have a higher quality. This technology has been widely used on various networks in Europe for a couple years now. In the United States, Verizon will be the only major carrier that will not support HD Voice until 2014 or later.
