AT&T uses Samsung Galaxy phones to test VoLTE services

AT&T uses Samsung Galaxy phones to test VoLTE services
At the moment, Samsung is selling VoLTE handsets only in South Korea, where it launched the first smartphone with Voice-over-LTE in 2012 (it was a version of that year’s Galaxy S III flagship). The company might start offering VoLTE devices in the US, too.

According to Korea’s Yonhap News, AT&T is currently using unspecified Samsung Galaxy phones to test its own VoLTE service (which should be available to users later this year). It’s not clear if the carrier is using older VoLTE-capable Galaxy handsets, or new models that are specifically made for AT&T. We also don't know if any of the test devices will be commercially available.

Voice over LTE literally means this: it sends your voice over a LTE network, not the standard GSM one, enabling features like HD Voice (which theoretically leads to clearer voice calls).

Despite the fact that AT&T seems to test VoLTE using Samsung handsets, its first official device to support VoLTE is the Asus Padfone X, which was announced at CES 2014 last week. AT&T did not say when the Padfone X would be released, though, and neither if it would have VoLTE at launch.

AT&T has yet to confirm exactly when it will roll out VoLTE across the US. But the carrier’s plans are to make the technology widely available Stateside before the end of 2014.

I vaguely remember hearing that same statement, only with 2013 listed as the year

You're right. I would assume they wanted to deploy LTE to as many markets as possible and then offer VoLTE once they've completed everything.

For starts Florin really need schooled their is no such thing as HD Audio, HD Video, takes so many lines of resolution get singal and than some many go back to complete the real singal one day the world will see truth and stop misleading the world into believing false pretense,

Nowhere in the article did it mention HD Audio or HD video. HD Voice DOES exists as T-Mobile already uses it. T-Mo, AT&T AMD Verizon will roll out VoLTE throughout 2014. Noe the next step is who will release LTE-A first - Verizon or T-Mo?

What about in the places att lte gets bad like in san Fernando valley att lte even with full bars drops down to 1 -2 mbps will that affect voice quality?

AT&T speeds in Chicago have dropped significantly... Call clarity is still great though. AT&T has to beef up it's network so it won't get congested like Verizon's did. They both have billions of dollars to use, and I'm sure they won't be afraid to use a lot of it this year.

You misinterpreted his question. VoLTE on AT&T is going to be sketchy if you ask me.

Yeah, Their LTE isn't the best. They need more towers or something.

They have enough towers. What they need is to update their towers to keep up with the traffic and bandwidth. T-Mobile and Sprint (Spark) don't have this issue since they run on 10x10 or 20x20 in the near future. AT&T has billions of dollars, yet they can't upgrade their towers like Sprint and T-Mobile can...

It's funny to hear you laymen speak about tower upgrades and such. VoLTE will not be released until it has been fully tested by us network professionals. Latency, bandwidth, quality will all be a factor in deciding when to launch. As far as tower upgrades, on sites that already have LTE installed, all that is needed to increase 'download speed' is to investigate the backhaul condition to the site. In 99% of all LTE locations, AT&T is using GigE ethernet services provided by either AT&T's Uverse or Verizon. It is a Fiber to the door service that allows a gigabit broadband connection to our switches. To speak on the HD audio, that is exactly what will be expanded on with VoLTE. The plan is that the bandwidth allowed for an VoLTE call vs a standard GSM/UMTS voice call will be such that the call/voice quality will be so improved that it can sound as though you are in the same room with the person. Standard voice calls have traditionally had the upper and lower portions of the voice frequency range clipped off the call due to the available bandwidth. VoLTE will not have any portion of the range clipped off. If you experience any problems with your LTE service, there is this thing called customer care, Call it or they will never know there is a problem.

I will add one more note, The difference between 3rd Party VOIP (voice over IP) and the new VoLTE, will be the ability of the carrier to assign a priority on the VoLTE data packets so that they have a much higher priority over that of a typical internet browsing or data downloading packet so that the VoLTE call has a higher standard of quality. If the network is congested, the VoLTE call will get top priority on the network and the other packets will have to wait.
