T-Mobile band 12 LTE spotted in Kentucky, Arizona, and other states

extendedrangelte

Yesterday, T-Mobile gave us an update on its network as it stands at the end of 2016. Extended Range LTE grew quite a bit in the final months alone, going from 225 million people in October to 250 million people in December.

T-Mo continues to expand its Extended Range LTE coverage, and here are some of the places that it’s been spotted lately:

Bono, Ark.

  • Neat, Phoenix! Hopefully it’ll spread throughout the suburbs surrounding Phoenix over the next few months.

    • Asael Delgado

      I am live in Goodyear and work in Deer Valley – I, too, hope they spread rapidly.

    • lomsha

      Yea, waiting for it to seep into Glendale lol.

  • The Waz

    What about Chicago

    • bkat11

      Chicago is coming real soon my gf is there now and she spotted it in gold coast

  • Dan

    Where at in San Diego?

    • The Waz

      West Philadelphia

    • pseudoswede

      I was in SD from 12/26-12/28. Zero reception on Coronado Island and SeaWorld.

      • George lopez

        Was in sea world during the week of Thanksgiving. Had phenomenal coverage and data was smoking fast. My cousin with Verizon was jealous. I have the S7 edge. Do you have a $50 piece of crap phone

        • JayQ330

          I have an s7 edge. what speeds were you getting in the area? I’m wondering what are the advantages with B12

        • Jason B

          B12 isn’t for speed, but for coverage similiar to Verizon’s band 13 and AT&T’s 17 (and 5/850MHz in some areas). It’s actually quite slow, especially in co-existence zones.

          When aggregated with a faster band, like 2, 4, or 66 (AWS-3), you get speed and coverage within the range of 2/4/66 otherwise the phone will fallback to straight band 12 as it has a range approx. 1.5-2.0x over midrange bands.

          But generally, more spectrum+bandwidth = more ways to relieve data congestion/traffic. And some signal even with slow speeds is better than none at all too.

        • George lopez

          Speed is great, but it’s not speed is what I was concerned with. Most people buy into the speed myth. It’s about latency. The latency was so low. It was great. Get a device that gets band 12, you will notice a huge difference in coverage

      • Dan

        Agree with you on coronado island

  • Raiterio Patterson

    Fayetteville? So it begins

  • Patrick McLaughlin

    Boise, Idaho got it about 6 weeks ago

  • Rob H.

    West TN desperately needs band 12 to cover the gaps between the splotches of band 4 and 2 to be able to compete out here with VZW and AT&T.

    • Dave

      Memphis area can’t deploy band 12 yet since its still in use.

  • Joe

    Even with B12 it gets congested quickly and you can’t do anything.

    • Landon

      Well it’s gets congested easily if it left alone but if carrier agradation gets activated then that when you see the full advantage of extended range LTE but unfortunately there still areas lacking this so you see abysmal speeds in those areas

  • Tanner

    SLC Utah has been lighting up with it as well.

  • Bruce Wayne

    I haven’t really kept up with things. What does extended range LTE offer that regular LTE doesn’t?

    • Tenb

      Band 12 travels a bit further and penetrates buildings a bit better than other frequencies. You definitely want a band 12 compliant phone on T-Mobile.

      • Bruce Wayne

        Thanks for the explanation. Is it a software thing whereby a simple switch flip will allow most current phones to use it or a hardware thing where only newer phones will support it?

        • It’s a hardware thing.

        • Bruce Wayne

          Ah, okay. Thanks.

        • SirStephenH

          Both the hardware and software have to support it.

          Some phones still come with the hardware for B12 but have it disabled in software for whatever reason but they’re increasingly rare.

          Any phone bought through T-Mobile now and days have at least bands 2, 4, and 12.

    • Jason Caprio

      Extended Range LTE aka Band 12 uses a frequency of around 700MHz. T-Mobile main Band 4 is 1700MHz for upstream, and 2100MHz for downstream. Band 4 yeilds the fastest speeds. Band 2 at 1900MHz is also used for extra bandwidth. 700MHz cannot give the highest bandwidth rates, but that lower frequency has better propagation through solid objects than the higher frequencies, and travels further. LTE Advanced combines all 3 frequencies for very high data rates when reception is strong.

      • BreakingData

        Very well put.

    • VernonDozier

      Band 12 has origins in the HDTV conversion. After HDTV was launched, excess airwaves went up for auction.

      During the Auction, Google famously committed several billion dollars to bid (and possibly buy) Band 12; which is very small in size but similar to 1980s cellular bands. In the last moments of the auction, Verizon placed a bid and won it. Because Google initially said it was going to bid, Apple (of course), didn’t include band 12 support in iPhone 5, iphone 5S, iphone 5C, iPhone 6 or iPhone 6+. Without support from IPhones, Verizon wanted to sell the airwaves because Apple had refused to support the band.

      As part of the negotiated deal for Band 12, Verizon also sold some of its towers to a third party (American Tower) because TMO’s network was designed for 1700 and 1900Mhz. This way the band could be deployed faster than if TMO built a network from scratch. T-Mobile decided, because of how small the slice of spectrum is, to use omnidirectional antennas. One omnidirectional antenna can cover 1,000 square miles. 3-antenna setups (typical to Verizon customers cover about 1/3 that area but also triple the amount of data available over that same physical 1,000 square mile area.) Further complicating things, omnidirectional antennas can’t be fine-tuned (or aimed) at a specific area. So areas where Verizon coverage is borderline, Verizon can re-aim an antenna. This is something TMobile technicians can’t do with omnidirectional antenna systems.

      Also, T-Mobile’s equipment is physically lower on the structure; further preventing range. As a result of shortcuts, T-Mobile’s network is engineered in such a way that it won’t support nearly as many simeoutaneous connections like Verizon’s network. The strength however is that T-Mobile knows how to make ads. It’s cheaper to make ads claiming similar coverage to Verizon than design a Verizon-quality network.

      After many awards, and third party tests, people know Verizon service is the best. T-Mobile is able to leverage Verizon’s brand (and Verizon’s investment into quality connections) by comparing themselves to a competitor but it doesn’t scale, coverage remains patchy because TMO doesn’t control how high on Verizon’s antenna structure it can setup equipment.

      • SirStephenH

        No one pay attention to the troll behind the curtain…

        T-Mobile uses three directional (NOT omnidirectional) antennas for all of their bands (2, 4, 12, 66) just like every other carrier.

        T-Mobile’s band 12 coverage has never depended on Verizon. In fact T-Mobile didn’t have band 12 coverage until well after the B12 auction when they started buying up spectrum and deploying it THEMSELVES.

        Verizon did not try to sell their B12 spectrum. It’s the backbone of their network and the only reason for their extended coverage.

        The whole height on the tower thing is BS as well. ALL carriers own their own towers AND lease space on other carriers’ and third party’s towers. The carrier that owns the tower always places their antennas at the top for better coverage, otherwise it depends on what deal carriers can work out with the tower’s owner. In the end it usually doesn’t really make that much of a difference.

  • Asael Delgado

    So, is Band 12 being used to cover the gaps?

  • PostmanLV

    Anybody hear anything on Vegas?

  • Jason Caprio

    -117, -120, -122dbm I see in a few of these shots. Those are nearly unusable low signals. I’m assuming they were taken deep indoors.

    T-Mobile needs more bandwidth in Fayetteville, N.C. Band 2 5MHz + Band 12 5MHz. That’s pretty bad.

  • desmond foucha

    I spotted band 12 lte in the New Orleans area finally

  • Mahmood Samater

    Even near T-Mobile arena reception is bad, how do they explain that.

  • Steve Park

    Wrong part of KY. How about Lville?

    • That guy

      I’ve seen b12 in Louisville…

  • Tom Pierson

    Don’t bother trying to use GPS on T mobile. It’s guaranteed to get you very lost.
    Phoenix AZ.

    • Bruce Wayne

      It works fine for me and there are a lot of skyscrapers and underground tunnels in Gotham.

    • BreakingData

      I have been to Phoenix a few times and never had any issues with the GPS on my phone.

    • Dash Dillinger

      I have absolutely no issues with my GPS in Phoenix.

    • vinnyjr

      Have both T-Mobile & Verizon, dropping Verizon when contract runs out. Have had T-Mobile for 8+ years and it blows Verizon away. GPS works fantastic on my T-Mobile device, locks on in 3 seconds inside my house and it is spot on exactly while traveling. T-Mobile is reaching over 300 million customers & gaining more monthly. T-Mobile upgrades it’s towers constantly, couldn’t be happier. Thank You T-Mobile, Thank You John Legere!!!

  • Jay Holm

    So how many total customers did Tmo reach by the 4th qtr of 2016? Reach 70m yet?

    • Walt

      Wont find out till late jan.

      • Jay Holm

        I know T-Mobile has to be close to 70m customers at this point! Still though after all of Legere’s efforts the past 3yrs I’m dissapointed the big 2 don’t seem to be losing a significant amount of customers.

        • Brandon

          The big 2 have lost sum customers. But it seems imo that the gains Tmobile have gotten more than likely came from people who either had prepaid, government phones, or Sprint.

        • Jay Holm

          Hmm…wonder if there will ever beaserious three times to the Big Two?!?!?!? Seriously, ATT & Vzn probably control close to 60+% of the entire U.S. market.

        • Acdc1a

          AT&T and Verizon have both lost a lot of phone customers. Pay attention to “connected devices.” That’s why it doesn’t appear that they’re bleeding.

  • Walt

    I’ve noticed that band 12 isnt on all cell towers (in areas already deployed with band 12) Imagine their coverage foot print if you had that? My guess is that there would be interference?

  • Rasheed Turner

    Columbus, GA just went live!!!

  • Carter von Seggern

    Band twelve in Anaheim.

  • Ken Metoyer

    Band 12 in Tucson, AZ too! Discovered it in the restaurant I work at, but noticed it switched to Band 4 when I stepped outside.

    • Leo Lopez

      What side of town?

  • Gavriel Ostrow

    Band 12 spotted in Lakewood,NJ! ocean county area.

  • Don Goyo

    I don’t get all the excitement with these deployments, those 5 MHz will do nothing but give the impression that you have signal, they don’t work, extremely slow, calls drop, people can’t hear you…shitty shitty shitty…

    • NavyVeteran

      LOL.. How do you know? Band 12 is faster and will alleviate traffic for those who don’t have band 12 capable phones.

      • Don Goyo

        I don’t think you even know what you’re talking about…

      • Landon

        Lol have you ever heard of carrier agradation this is the combination of two or more bands too increase capacity so still people would be using band 2 and band 4

    • Walt

      Max speed of band 12 5×5 mhz is 37mbps. Not bad

      • Don Goyo

        My comment is based on my actual day to day experience, not theoretical data or assumptions…

        • Trevnerdio

          The difference between traditional theoretical speed numbers and these LTE “theoretical” maximums are that they are realistically achievable, assuming low load. They’re not lab results, they’re real-life resilts.

        • Don Goyo

          Assuming low load, if you work/ live at a metro area, you’ll experience what I’m saying.

        • Trevnerdio

          I know exactly what you’re saying. Orlando around Disney is unusable during peak hours. 20MHz can’t save them there. My only point is that the 37 is totally realistic, not a lab statistic.

        • Landon

          20 mzh there isn’t LTE advanced on Orlando with band 12 band 4 and band 2 it should be at 45 mzh

        • Trevnerdio

          It may have been CA, I didn’t know how to check last time I was down there. Pretty certain my V20 can only do 2 bands anyway, not 3.

        • Landon

          No I think your phone supports CA 3 well the V20 supports AWS 3 so I doubt that it doesn’t support CA 3

        • Trevnerdio

          Hmm…I’ll look more into it. The only options I can find are B12/B2 or B17/B2 (I think) and I know T-Mo doesnt use 17. The phone doesn’t seem to like to use CA on its own…still waiting on an update for this phone… -_-

        • Landon

          That sucks then by update you mean the nogoat update

        • Trevnerdio

          It shipped with Nougat, but yeah, the first system update. One just came out, but all it does really is fix a root exploit. Go figure.

        • Landon

          Well t mobile should have CA on Orlando I think it’s a strong t mobile market and if t mobile doesn’t have CA then they are really behind and more if they don’t have CA on area as dense as Orlando

        • That guy

          Your V20 can and does do 3 band aggregation right now. Mine does it beautifully with b2, b4, and b12. However, you have to be in engineering mode to actually see any indication.

        • Trevnerdio

          That’s where I was. Can you screenshot the screen you were on for me?

      • patt

        And if congested you are lucky to see 0.50mbps.

    • Landon

      Yes it’s shitty if there isn’t carrier agradation but if there is carrier agradation speeds aren’t much of a problem trough there areas that only have band 12 so literally you can only make calls and texts because data speeds might be unusable if you having problems even with calls and texts then your issue isn’t band 12 is bad coverage on your areas calls and texts no matter how heavy the congestion is they will always be prioritized over data usage

      • Don Goyo

        If the purpose of band 12, is to get coverage where other bands can’t, then carrier aggregation won’t solve anything.

        • Landon

          Carrier agradation is too combined bands too ethier increase capacity or increase the range of multiple bands normally phones will only connect too band 12 indoors outdoors they simply connect too band 4 or 2 of course if there isn’t any of those two bands then it will connect band 12

        • Don Goyo

          The principal purpose of band 12 is to provide coverage indoor, where there’s no band 4, if you get both, fantastic, if you only get band 12, as it happens on metro areas, it is useless, because 5 MHz aren’t enough for the amount of people living/ working in buildings where band 4 can’t penetrate.

        • Landon

          Well it depends though if you are on a really deep in a building yes you only got band 12 but both band 2 and band 4 aren’t that bad at penetracting most buildings you are saying that all buildings in a city have really huge building that reaches the sky but well if data speeds are slow then use WiFi at least you can call and text which before you couldn’t if you were on a big building

  • Vontae Everton

    From Wisconsin traveling to Mississippi had straight 4glte the whole trip

    • Asael Delgado

      Cool! :)

  • Dan

    Can tmobile put up band 12 on every tower in a city they have a license for or will that cause interference?

  • Philip

    I got a problem. I cannot get any data signal anymore at my cube in the office. It was fine for many years until two days ago. If I go to the window, I can get data. What happened? Yep, it happen to two different phones at the same location, so its not a phone problem. What number do I call T-mobile to let them know?

    • Blqh

      611 or Twitter give them the location and explqin what happened, You could also email john legere . Also well make sure data is turned on in the phones settings.

  • mikeZo6

    Hey TMO everyone of those screen shots !
    signal was F horrible big time -80 is good signal, -120 is no service
