Ericsson chosen by T-Mobile to build out the new 700MHz and 1900MHz LTE networks


Ericsson revealed yesterday evening that it’s been chosen by T-Mobile to build out the company’s newer 700MHz and 1900MHz LTE networks. And the news should come as no surprise, since the Swedish company has been used in the past to build a lot of the first T-Mo LTE network.

Ericsson has started building the new 4G base station equipment for the A-block, band 12 LTE network currently in its infancy. As well as that, it’s also involved the infrastructure required for the new 1900MHz LTE network, and is providing what Kevin Fitchard of GigaOm calls “baseband processing glue” that helps bring all the different frequencies together.

This “glue” is a technology known as carrier aggregation. In the most basic terms, it helps T-Mobile operate all its LTE bands (2,4,12) and unify them in to one really fast system.

“Using an LTE-Advanced technique called carrier aggregation, Ericsson will be able to bond the downlink transmissions of two or more bands in to one big fat data pipe.”

We’ve not had any official word from T-Mobile on when the carrier aggregation is going to be implemented.

Ericsson is also reportedly heavily involved in the technologies behind T-Mobile’s VoLTE and Wi-Fi calling services. Or at least, involved in the technology that makes it possible to transition smoothly between a regular 2G voice call, VoLTE call or Wi-Fi call when you move between different connections.

    Smart move love Ericsson technology.

    This is great news. Ever since I switched to T-Mobile in November all they have been doing is improving. I’ve never had faster speeds in the city and they have improved more in the past 6 months than Sprint did in a year and a half. Can’t wait to try out the new 12 band. Hopefully the nexus 6 is compatible or the note 4 will do.

    • EffortLess

      From T-Mobile’s Note 4 info:
      Band (frequency):
      Quad Band GSM; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850); LTE: 1, 2, 3, 4, 5, 7, 8, 17

      • yankeesusa

        I tend not to pay attention to info from tmobile site. But you cold be right and if that’s the case I will pass on this. Too expensive for it not to have band 12

        • Jay Holm

          Also too new not to have it, at this point there isn’t any reason not to!

      • Marcelo_L

        If the GNote 4 doesn’t end up having Band 12, then there’s not much reason for folks to upgrade with GNote 2/3. It’s an investment in future use as that band gets deployed, and if the phone didn’t have it, that would seriously limit it’s usefulness.

        Then again, it could be like our TMo GNotes, which we KNEW had LTE capability, but required an OTA from TMo to turn on what we’re presumed was there since the beginning, but was only disabled out of the box.

        • MJ

          So will iPhone be the same way, a software update to enable it?

      • NOYB

        Note4 has band 12 its lock and t-mobile is not going to say it does because it’s not in used yet

      • Laststop311

        BIG F YOU to all the people saying just get the note 4 FCC says it does band 12 so its good to go. Told people until t-mobile says it will work on their network nothing else matters. If they dont unlock the ability in their software it will never work even if it has the hardware. Staying with my note 2 until there is definitive proof.

        My phone is paid off so to add +31 to my bill i better have 100% guaranteed band 12 use or I’m not paying it.

    • Bryan Pizzuti

      The Sony Xperia Z3 is supposed to support Band 12.

      • yankeesusa

        yea and the moto x also although i prefer the xperia. I wish my g3 had the band. oh well.

        • Bryan Pizzuti

          Me too, but I’ll happily sell it to pay for the Z3.

        • yankeesusa

          I would too, i just love the knock on feature and ir blaster, not to mention I have gotten really used the buttons on back and amazing screen with no bezel.

        • Bryan Pizzuti

          I hear the Z3 has a version of knock-on. And while I’ll miss the rear buttons, I wouldn’t mind having an IP65/68 water resistant device.

        • yankeesusa

          The water resistance is completely worth it. Its going to be interesting to see what price it will be selling at. The z1s started at 528 on release date.

        • Medion

          Moto X doesn’t support band 12. XT 1092 shown at the press conference does, but that one hasn’t been announced for release. The current Pure Edition has no band 12 support.

        • yankeesusa
  • Alex Zapata

    This is fantastic news!

  • Adrayven

    Sadly my 6+ doesn’t support band 12, but it should be in full swing/use by this time next year and the 6s should support it; so not a deal breaker yet. Will be upset if the 6s doesn’t support it though..

    • brybry

      I’d worry more about the #bendgate O_O

    • Unlikely, as band 12 requires different RF filters.

      • TechHog

        Why does that make it unlikely? I don’t see why that would matter for a phone releasing in a year.

    • There is no 6s coming. Quit making up phones. They released 2 versions for a reason and they’re done until next year.

      • PHL

        Did you not see the “next year” part of Adrayven’s post?

    “… technology that makes it possible to transition smoothly between a regular 2G voice call, VoLTE call or Wi-Fi call when you move between different connections.”

    I have never been able to transition a call from WiFi to Mobile Network, call is always dropped.

    • James Shaggy

      That is a typo. There is no technology that will transition VoLTE/Wifi call to 2G call or vice versa. That being said it is possible to transition a VoLTE to Wifi call.

      • Anon

        Not entirely true, UMA used to be able to smoothly handoff from a WiFi call to 2G or from 2G to a WiFi call.

        • Ky

          I think he meant to say there is no IMS technology to go from VOIP calls to 2G calls. UMA was from voice to voice transition.

    • Alex Zapata

      I think it should be VoLTE to UMTS, which TMO already has in the form of eSRVCC.

    • Melanie323

      i can do it but depends what phone from tmobile samsungs suck at that they drop the call when u making a call on wifi and u move away from the wifi signal call drops. LG phones on T-Mobile are much better at that i had the phone on speaker while making a call on wifi and i moved away from the wifi signal “4G” kicked in and kept the call connected didnt drop on Lg yeah.

      • caquito

        I have only used Samsung in T-Mobile, first S3, now S5.

        • J Cav the Great

          I’m not sure how I am able to, but I use WiFi calling a lot. I have an NFC sticker by my front door to switch on my Wi-Fi. I have made calls while on WiFi and then walked out the door to go walk my dogs away from WiFi. I always has seamlessly transferred to my HSPA+ connection w/o issues….

    • Justin Merithew

      I believe calls were always dropped when leaving WiFi with the original iteration of WiFi calling, but the update that newer phones have received and future phones will come with sounds like it will make a smooth transfer. I own an M8 with the update, but haven’t had a good opportunity to test it yet, so I can’t really say for sure.

  • Frau Engel

    Sehr nett.

  • dayaram

    So band 12 cant be added with a software update??

    Thanks in advance.

    • No, it requires a different RF frontend chip.

      • Mj

        Does iPhone 6 have it?

        • I don’t know. If it did, band 12 would probably be listed in its specs. Since it isn’t, I doubt it.

          Moreover, even if the iPhone 6 had the proper hardware, an already sold device has its own FCC certification and it cannot operate on a band that it wasn’t certified for. Only new devices with a different certification could.

        • Ryan Wilkins

          No, it doesn’t. Hopefully in the next incantation it’ll support band 12. But that’ll be a year from now.

          Proably 6s

  • turtle6988

    this is partially true Nokia is also building out these networks for T Mobile

    • Chris

      Nokia Siemens Networks joint venture does. Technically not solely part of Nokia.

      • enkay1

        Siemens sold its stake to Nokia and Nokia shed its mobile phone business to become Nokia Networks.

  • This is not accurate: “build out the company’s newer 700MHz and 1900MHz LTE networks.” The source report reads: “build new LTE systems in the 700MHz and 1900MHz PCS bands.” TMUS already operates LTE on band 2 in some markets.

    The 2nd best news is this bit: “Ericsson also revealed it’s deploying small cells in T-Mobile’s network. These tiny little base stations pile a lot of capacity into small area, making them ideal for feeding our growing data appetites in dense crowded areas like malls and outdoor plazas.” (emphasis mine)

    • Jay J. Blanco

      Tmobile just started launching 1900mhz lte. Original they started off in band 4
      And also tmobile has to lay fiber and microwave base stations so yes build new systems…

  • Brian Perez

    How about getting rid of this terrible 2g n 3g and make it all 4g 4glte..

    • Chris

      That’s what they’ve been doing… It’s not that easy to just switch stuff up. They have to work with local government (cities, state) as well as other regulators to make sure they are not interfering with anything once the transition is done.

      Patience young one soon you’ll be able to fly.

      • Brian Perez

        Lol i wasnt talking about me lmao im talking about otger areas that arent as fortunate as mine.

  • x1ann

    I am a new Tmobile customer here with an iPhone 6 and I have to say that my calls never transfer between Wifi Calling and 4G or LTE. Once I am out of range the call drops. Am I the only one?

    • S. Ali

      WiFi calling should handoff to VoLTE not HSPA 4G, make sure “voice and data” is enable under LTE settings.

  • William Burr Winans

    Recently T-Mobile upgraded all the towers in Aiken, SC but they are all working on Band 2 and Band 4 is twice as fast. Is there a way I can tell my phone to choose either Band 2 or Band 4?

    • JamesG

      Nope, it will choose automatically. AWS(band 4) will be the better option

    • enkay1

      What phone do you have? It is possible to force a certain band if you have the right phone.

      Automatic is probably still the best option because your phone will switch between them for the best experience.
