AT&T's VoLTE Launches May 23 in 'Select Areas'
by Karl Bode 02:43PM Thursday May 15 2014
Confirming rumors from earlier this month, AT&T has confirmed the company is getting very close to launching their version of higher-audio-quality voice over LTE service (VoLTE). According to an AT&T announcement, AT&T's belated VoLTE implementation will launch on May 23 "in select areas" in Illinois, Indiana, Minnesota and Wisconsin, and "will continue to expand on a market-by-market basis." Handset support at launch is also expected to be very limited, with VoLTE only supported on the Galaxy S4 Mini at launch, "with more devices to come." AT&T had originally stated they'd hoped to launch VoLTE before the end of 2013, though like Verizon faced delays due to interoperability issues.

No Surprise

It's no surprise that AT&T is rolling out first. They have the most to gain by using 700 MHz for voice. Penetrates much better than their current voice frequencies.

Re: No Surprise

Huh? There isn't much difference between 700MHz and 850MHz propagation and AT&T owns 850 licenses almost everywhere across the country, with a few exceptions.

Re: No Surprise

In NH and a few other areas, they are using PCS for HSPA+ and 700 for LTE... should be a HUGE improvement. For most of the country, you are right though.

Re: No Surprise

Okay, I'll give it that. That's only a very small area though.

Re: No Surprise

LTE also uses 1900 and AWS, a majority of VoLTE will go over AWS... look at the markets it is launching in and look at how much AWS spectrum AT&T has deployed in those markets in the past 6 months.

Re: No Surprise

VoLTE will go over any LTE band, so it will be mostly split over 700 and AWS for now, with some PCS and CLR, and it will eventually run on all 4 bands in many different parts of the nation...

Utter nonsense, 700 MHz LTE has worse coverage than 850 MHz UMTS.

Re: No Surprise

I didn't say anything about the coverage provided by the various technologies and spectrum combos, did I? I said that 700Mhz signals and 850MHz signals have similar propagation characteristics, which is a fact.

The reduced coverage provided by LTE on 700MHz vs UMTS on 850MHz has nothing at all to do with the spectrum being used and everything to do with the amount of TX power available out of the power amplifiers used in each technology. LTE has lower TX power. It is as simple as that.

Re: No Surprise

No, actually it's not as simple as that. It's the code rate and how "fragile" to use simple terms the LTE signal is, NOT the transmit power. And you IMPLIED that LTE on 700 would offer better coverage than UMTS on 850, since THAT is the choice presented.

It's been really strange. Initially, Verizon's LTE was way out-covering their CDMA off the same towers, but now it seems LTE is more fragile than CDMA or AT&T's HSPA+, but there are a lot of factors, including TX power, channel width, and how OFDMA allows decent data transmission with low signal strengths.

I've heard this before but I've never understood... Why does this happen?

Re: No Surprise

Basically, LTE squishes more bits in the same spectrum, so those bits are more sensitive to things going wrong. That's the simplest way I can think to describe it

Re: No Surprise

Well, there's a lot to it. OFDMA is more sucesseptible to issues, even though it can in theory, also work with a weaker signal. Also, they are putting out big fat 5x5 and 10x10, and even 20x20 channels out now, whereas EVDO was 1.25, and even HSPA was 5x5.

HD = Worse?

Am I the only one that thinks the HD audio on AT&T's Demo sounds worse than the regular? Very tinny and no bass at all. If that's HD, I'll stick with regular!

Re: HD = Worse?

VoLTE is nothing more than the carriers to turn down the old 2G networks and re harvest the spectrum. They can also go all IP and that simplifies their network.

Nobody has said when and if voice gets treated like data, and that counts against your GB...but it's coming...

Once they do that, compatibility goes to hell, and consumer lockin is achieved. Its serves a few interests....

The "HD" piece is only as good as the other end of the receiver. They are going from ultra compressed to highly compressed. Yawn.

Re: HD = Worse?

You can look for them to start turning down 2G in some markets before the end of the year. Those markets may be the ones they are turning up VoLTE.

Source? Or, are you just speculating?

That's because voice won't be treated like data. They will be counted separately, just as they are now. And what do you mean by "compatibility goes to hell"? Please elaborate.

It won't be counted as data... just as TV and phone on U-Verse are not.

Re: HD = Worse?

You're joking right? At this point AT&T can't differentiate between TV, phone and internet data and is why they don't enforce usage caps.

Re: HD = Worse?

I know they have issues with that, but incompetence in doing some basic accounting on bandwidth on AT&T's part doesn't mean that it's not technically possible. It's all about the VLANs.

Price schedule

How will they implement price discrimination (»en.wikipedia.org/wiki/Price_disc···lanation) when everything is data? Will they continue to bill voice calls as "minutes," even on unlimited minute plans, or will they charge per byte?

Re: Price schedule

VoLTE will be voice minutes, yes.

Cross-carrier interoperability?

Will this be interoperable with other carriers once they launch VoLTE?

Re: Cross-carrier interoperability?

Eventually, probably. For now, even LTE data roaming is a rare beast with most roaming falling back to UMTS or even GSM.

caller id ?

Okay now is time for all cell companies to support full caller id. i can live without volte.

T-Mobile actually has this already this feature (the call id Name ID). It's $3.99/month per line.

how do you know

So if your handset is using VoLTE how would you know it's using that?

Re: how do you know

It won't drop down to 4G/3G when making a voice call like it does now.
