AT&T First To Deploy VoLTE Network for HD Voice
AT&T First To Deploy VoLTE Network for HD Voice

News of AT&T's HD Voice service marks the start of what so many have been anxiously anticipating. All the major wireless carriers will eventually offer high-def voice, but AT&T appears to be the first to deploy it over a VoLTE network. The benefit: being able to talk and surf the Web at high speeds at the same time over an Internet or IP network.
 



The second-largest wireless carrier in the United States, AT&T, is on the cusp of rolling out what could eventually mark a strategic differentiator: high definition (HD) voice. The telecom giant is tapping its all-IP Voice over LTE (VoLTE) network as it brings its HD Voice to select markets, making it the first carrier to deploy VoLTE for high definition service.

HD Voice is a wideband technology that promises crisp call quality with reduced background noise so a caller feels like he's right next to the person on the other line. Historically, voice calls have been transmitted on a limited frequency of 300 Hz to 3.4 kHz. To provide better call quality, HD Voice greatly expands that range from 50 Hz to 7 kHz -- and even higher -- to bring high definition calling to the handset.

Limited Market To Start

With its rollout, AT&T is making a bold promise: Customers don’t have to choose between faster data speeds and clear voice quality. HD Voice promises to let you talk while surfing the Web at 4G LTE speeds with no compromise in terms of data speed or voice quality.

However, to get the benefit of HD Voice, AT&T indicates both the caller and receiver need an AT&T HD Voice capable phone and must be located in an AT&T HD Voice coverage area. For now, that means an extremely limited market.

HD Voice from AT&T will initially be available in select areas of the U.S., in Illinois, Indiana, Minnesota and Wisconsin, starting May 23. The company said it will continue expanding on a market-by-market basis.

The Samsung Galaxy S4 mini will be the first device to include HD Voice capabilities. AT&T promised to serve the much-anticipated technology to other devices soon.

Early Advantage

We caught up with Jeff Kagan, an independent technology analyst, to get his take on AT&T’s HD Voice service rollout. He told us the announcement marks the beginning of what so many have been anxiously anticipating.

“We are expecting all the majors to offer this service sooner or later. AT&T appears to be the first to market,” Kagan said. “High definition voice will be very important going forward on all-IP, Voice Over LTE. It lets customers talk and surf the Web at high speeds at the same time over an Internet or IP network.”

Competitor Verizon Wireless plans to roll out HD Voice sometime this year, while Sprint has also been moving quickly in the meantime with its own high-definition voice technology. (continued...)

HD voice is not a "strategic differentator" because everyone will have it by the end of the year in some flavor. Seriously?

AT&T is not the first to launch VoLTE because they have not launched it yet. Zero customers are using it, because no handsets are available. And regarding HD Voice, T-Mobile has already had that nationwide for over a year.

Two misunderstandings.
Not 3.4Hz, but 3.4KHz.
Not 7Hz, but 7KHz

Completely wrong. Sprint launched HD Voice service two years ago, and T-Mobile launched HD Voice service in 2013 on the iPhone. Both smaller carriers offer it, albeit in limited markets.

AT&T is, however, the first to deploy VoLTE.
