AT&T plans to begin deploying HD Voice's improved voice calling to customers later this year, an executive with the carrier revealed today.

The feature, which has been long touted by the wireless carriers, uses hardware and software components on both the phone and on the network to significantly enhance voice clarity while reducing background noise. The feature devotes more frequency to handle the amount of audio coming in and automatically kicks in when both handsets support it.

Speaking at the VentureBeat Mobile Summit in Sausalito, Calif., Senior VP Kris Rinne said that the carrier's support for … Read more

Safari has won back some of the ground it lost recently to rival mobile browsers.

Apple's iOS browser captured 61.79 percent of all mobile browser Web traffic seen by Net Applications in March. That was a healthy rise from the 55.41 percent tracked in February.

Safari remained firmly in the lead last month, followed by the default Android browser in second place with a 21.86 percent share and Opera Mini in the third spot with 8.4 percent. But Safari has seen its share of Net Applications' Web traffic rocked by the competition.

Is it just us, or did it seem like T-Mobile was taking a lot of shots at AT&T during its "Uncarrier" event today?

Executives, including T-Mobile CEO John Legere, mocked AT&T's confusing data plans, its network speeds, and even the paperwork required to sign up for its services.

AT&T, meanwhile, didn't have much to say about T-Mobile's comments … Read more

In an effort to show the potential of the unused frequencies in the broadcast TV spectrum, Google has launched a trial program that will tap the so-called white spaces to provide wireless broadband to schools in South Africa.

The Web giant announced today it will use the unused spectrum to provide Internet access to 10 schools in the Cape Town area. The goal of the trial is to show that wireless broadband can be provided over white spaces -- the unused spectrum that sits between broadcast TV channels -- without interfering with licensed spectrum.

"White space has the advantage … Read more

T-Mobile announced in December that it would eliminate subsidies on cell phones this year, hinting that it would also switch up its mobile plans and go no-contract. Now, it's expected that the carrier will debut its new plans at an event scheduled for March 26.

However, TMoNews seems to have gotten its hands on at least some of the pricing information a week in advance.

According to a TMoNews, T-Mobile will be offering two types of plans: the "Uncarrier classic," which will be offered by national retailers like Target and Best Buy, and "Value" plans … Read more
