T-Mobile Searching For VoLTE Specialists According To New Job Listing

A new job listing on T-Mobile’s website might hint at the company’s plans to roll out Voice-over-LTE services, just months after stating they were still “evaluating” the technology. Voice over LTE is pretty much what it sounds like, technology aside, it’s utilizing 4G networks for both voice and data services, not just data. As it stands today, both AT&T and Verizon are using LTE for data on just voice only, though Verizon has said they plan to rollout VoLTE later this year in limited markets.

According to the job listing, T-Mobile’s new engineer will give 4G voice “lab trials” and test “multiple vendor products.”

Earlier this year, T-Mobile’s Senior Vice President of Marketing, Andrew Sherrard had said that T-Mobile would look to use an IMS based Wi-Fi calling client for voice instead of VoLTE. T-Mobile’s Chief Technology Officer Neville Ray has also hinted that T-Mobile could deploy Voice over HSPA.

A T-Mobile spokeswoman has not yet responded to FierceWireless request for comment.

    What if….

    T-mobile upgraded all their towers to LTE and phased out all regular voice and did VoLTE instead?

    Wouldn’t that open up more spectrum for data?  I know that would be a ways off, but it would be really cool.  I wonder if they would just do away with voice plans all together and have everyone do data plans instead…

    • techymexican

      well they could just phase out 2G and have Voice over HSPA since they invested a lot of money on HSPA already. and use the 2G spectrum for LTE

      • UMA_Fan

        I don’t think we would see that realistically.  The good thing about the 2G gsm network is that when people who reside internationally use their phones in the US they roam off T-Mobile and they make tons of money off international roaming with their partner carriers.  It’s a source of revenue that Verizon and Sprint simply can not have.

        This is also why I find it surprising that at&t plans to shut off gsm completely in 2017.  That would give international travelers with gsm only phones the choice to only roam on T-Mobile giving them all that revenue.  I’m sure by then though at&t expects the amount of people travelling here with gsm only phones to be virtually non-existent and is banking on them to roam on their HSPA/UMTS since their bands are international friendly.

        • Trevnerdio

          Yeah by then 4G will probably be pretty old hat so they’ll have some 3G/4G roaming in place.

        • MarcusDW

          That was my thought.  I’m pretty sure the rest of the countries will advance their networks and devices long before 2017.

        • TMOTECH

          Yep.

  • Josue

    TMOUSA better get on this LTE thing fast… they are behind the other 3 carriers.. and its funny even Metro PCS has LTE (even if its not even actual LTE) but come on tmo you slackin

    • ogopogo

       Their “slackin” has allowed them to start deploying the most advanced version of LTE – Version 10.

      • Eanfoso

        Don’t forget t-mobile USA WILL BE the first carrier in the new world to offer a quad core processor phone; htc one x+

        • JBrowne1012

           Just like we were first to launch Dual-core

        • juanmondragon

          Yea and guess were that first dual core smartphone is right now…in the toilet with the other crappy products

        • MarcusDW

          LOL

        • Josue

          im sure TMO will price it fairly ($499 with $50 M.I.R)

    • JBrowne1012

       T-mobile is not slacking at all HSPA+ is currently more reliable than LTE

    • UMA_Fan

      It doesn’t really matter that much.  LTE with no backhaul gives you nothing.  That’s why T-Mobile HSPA+ 42 will always be better then Metro LTE.  Sprint and At&t are the two worst national carriers when it comes to the fiber backhaul part of it.

    • Trevnerdio

      So? HSPA+ has nearly indistinguishable speeds most of the time…LTE is nothing to rave about, it’s just fairly expandable.

  • Ninalana

    when is tmobile getting lte in chicago keep us updated on LTE please.

    • http://tmonews.com David

      It’s far too early to be asking this question, T-Mobile hasn’t made any announcements about LTE markets, launch dates etc. You won’t hear anything about this for at least another 6-7 months, at the earliest.

      • nivekkev

        So on that note, is it also to early to know if any of the new phones coming out will have LTE radios already in them for when LTE goes live?  I have an upgrade in October but I don’t want to get a phone without LTE with the network lauch just around the corner…

  • loueradun

    Since T-Mobile already has Wi-Fi calling, it seems like VoLTE should be a pretty easy next step from a development standpoint.  Obviously bumping the bandwidth to make sure everything runs smoothly is a completely different animal.

    • UMA_Fan

      Which raises the question for the industry since all carrier have committed to voice over LTE, will they use that concept as T-Mobile has and extend it to WiFi?

  • UMA_Fan

    If they went the IMS over LTE route I wonder if a call could switch from LTE to WiFi without dropping?

    • TMOTECH

      That was the initial plan, using the same tech as Wi-Fi calling since it is already in our infrastructure.  But I think they are realizing that VoLTE is more efficient. 

  • AndrewTMobilecustomer

    David,
    What type of LTE is Sprint going to be using, once released fully later this year & into 2013.

  • FILA

    prepare to have a 2 hr battery on all smartphones if they go over to Voice on LTE, which will happen, but christ 4G sucks down alot of battery lol, compared to 2G

    • J-Hop2o6

       They get more efficient as the chips advance like the Qualcomm S4 chips. 3G used to be a battery hog when it first came out in phones.

    • Durandal_1707

      Actually, I’d expect that using LTE for everything would probably increase battery life, since you’d be able to turn the 2G/3G radios off, instead of having to have everything running simultaneously like you do now.

  • William

    I’m not sure how good T-Mobile’s LTE network could be, especially if they want to use it for VOIP services. They don’t have much extra spectrum to work with. With mobile networks, the lower the frequency, the better a network can penetrate buildings and go longer distances. Also, the higher the bandwidth allocation, the more capacity and speed a network will have. Here’s a breakdown by carrier:

    Verizon: 700 MHz with 20 MHz of allocation.
    AT&T: 700 MHz and 1700 MHz with 10-20 MHz of allocation.
    Sprint: 1900 MHz and a small amount of 800 MHz with 10 MHz of allocation.

    Assuming that T-Mobile will use the 1700 MHz band for their LTE network, how much allocation can they really have? Since is seems that the 1700 MHz band is going to be heavily fought over (AT&T and Verizon each want parts of it), I doubt that T-Mobile could offer a network with more than 10 MHz of bandwidth allocation. I just don’t see how they could have good LTE speeds if they also want to use it for voice.

    • Bronze 6

      T-Mobile has a fairly large chuck, irrc, T-Mo has 20Mhz in most areas now.

    • Trevnerdio

      It was rumored that they’re going to have 20 like Verizon, like Jim said. And I think Sprint actually uses some 5MHz blocks, that’s why they’re so slow in some areas.

    • TMOTECH

      In the market I work in we currently have 40 MHZ of spectrum in the AWS band. That is 20 up and 20 down. This is what we have in most markets. Other markets are gaining AWS Spectrum from the AT&T deal and also from the AWS swap we are doing with Verizon. I dont know where you got your numbers from but they are wrong. 

  • Hello

    What am I supposed to do when the GIANT yellow sprint ad takes up my whole One S screen?! I’ll tell you what I do, I hit back and the browser closes, and I don’t come back for a few days later.

    • Anton Yatsenko

      And the worst part is – you can’t close it! The Piece of Crap keeps following you as you navigate!

  • Steve

    If LTE costs more in terms of battery then why do I want to use it for voice.  I think the value of using it for data versus HSPA+ is also questionable in when considering power costs.

  • Bmg1001

    LTE and Quad Core’s don’t go together, with HSPA+ 42 becoming reliable and fast just as LTE, T-Mobile could launch some killer quad core phones utilizing HSPA+. Quad Cores are only incompatible with LTE bands, not HSPA+ bands right?
