AT&T Foundry

A tour of AT&T's Foundry special R&D place included a test of its upcoming LTE network. Engineers have tried to mimic real-world scenarios in the Foundry, instead of showing theoretical speeds, and the trial got 28.8Mbps downloads, and 10.4Mbps on the upload side.

The engineers explained that AT&T is using MIMO antenna setups, and its LTE network is getting build to operate in two spectrum ranges - the 700MHz which it got from the FCC auction, and the AWS one it had, to which it will add a lot more with the purchase of T-Mobile.

The demo setup wasn't even using any carrier aggregation, that is, adding your spectrum to someone else's on the physical layer to create the required bandwidth, and  improve services, like a roaming agreement for LTE transmission.

AT&T's LTE network is expected to start rolling out this summer to select markets, and there might even already be some devices getting produced to run on it, like the rumored 10" Dell Streak Pro tablet.

LTE is useless with a data cap!

true such a downer. But then again that's the way the industry is moving. Even Verizon says they won't be unlimited for much longer.

yes sir it is, what's the point in having LTE if it's capped I say if we won't At&t to give us more data for say 10GB cause 2GB isn't enough and we all know that unlimited is just that then we need to stop using they're services and by doing that we force them to lower their prices and give in to our demands if not they will keep screwing up over especially now with the new "Secret data consumption" Lawsuit filed against At&t we can pull it off we have proof

Holy crap. This is amazing. I can't wait. I know that even though this is a SIM and real world results may be slower, I don't think it'll be that drastic at first anyway because carrier aggregation will boost it. I hope anyway.

Despite the data cap, AT&T is moving forward and I like what they're doing. I have the Inspire and I'm looking forward to see what LTE has to offer.....id say that they should let those who have 4G phones to have unltd data since not everyone has 4G phones yet

Based on my experience here with ATT to your "let those who have 4G phones to have unltd data since not everyone has 4G phones yet." You will be laughed at ridiculously. Most people with 3G don't have unlimited and basically someone would tell you go fuck yourself haha.

How does this compare to Verizon's LTE?? I wonder if they will produce faster speeds in real time.

NO ONE IN THE UNITED STATES, HAS 4G HSPA+,WIMAX and LTE ARE ALL CONSIDERED 3.9G if you can't get 100Mbits DL it's not 4G They are lying to us everyday, making us think that 3.9G is 4G the ITU said HSPA+,WIMAX and basic LTE where not capable of achieving such speeds, but guess what happened about a few weeks later THEY changed their minds OUT OF THE BLUE does anyone know why? IT"S BECAUSE THE US CELLPHONE COMPANY'S PAID THE ITU TO CHANGE THEY'RE minds so that, AT&T,T-mobile,SPRINT AND VERIZON COULD SELL US THE BADGING on a phone that clams 4G speeds when they can't give the results. People we're paying for a service that doesn't exist (at least not yet) in America. Don't be fooled Ex: Why do you think people on Iphones get better speeds then on a phone that's branded 4G? it's because even though the iphone is 3G it runs on the same Hspa+ network as the new "4G" handsets like the Atrix or Infuse, but if you walk into a store and clearly test the "4G" speeds you'll find that the new phones are CAPPED and they're limited so they don't sell as much as the Iphone after all the Iphone is At&t's best selling product if you let the newer Hspa+ phones achieve the same speeds as the Iphone 4 or better no one would buy an Iphone. Don't let these Company's steal our money educate your selfs so we can put a stop to this American theft.

You're right man, it's all a conspiracy set in motion by the illuminati and the free masons to get us all to buy iphones!

make fun of my theory as you may,but the truth is the truth and if your like the rest of Ignorant America and really don't care if your getting robbed then so be it, But I am part of a very small piece that turned on it's light switch a very long time ago and I will not stand for this capitalist and fascist country to keep ruining our life's while the keep stealing money from us and they keep killing our troops in the middle east or did you forget that Bush knew about the 911 attacks and knowing he had the power to stop them he let it happen. This country is no longer the greatest place on earth or will it ever be. Many people have told me to leave if I don't like it and to tell you the truth I will because I want to live in a real civilization not one run by corporations. Everyone else is up to modern times while America 's still trapped in the 1900"s. The funny thing about it is even if we aren't bound by chains we as the American people are still slaves and our masters up in Washington command us when we should command them. This country will never change if we never take it back

of course.. all your information is old and the governing bodies came back and said that all current "4g" technologies now count and that 100mb/s threshold is no longer a factor. Wimax, LTE, and HSPA+ are now all concidered 4g officially.. regardless of speed.

Hows the tinfoil hat?

hey so where is it that has a better form of government then the us? europe is the same except with small socialist factors, and when they wernt like us, how did that work for them? cough warsaw pact communism failure cough... how bout russia? didnt they function so well under communism/dictatorship? Even fascist italy and nazi Germany, how long did their third italian empire and third reich last? what about the middle east with their princes? wait hasnt there been a war there for pretty much ever? okay so then asia right? well japan folows a similar government to us, and china follows capitalist communism dictatorship thingy... and how is that working? well they have a booming economy, but their citizens are uneducated, poor, and starving... millions die just from starvation! and are there any other countries that are worth examining? becuase south america and africa are really not places where u wud want to move to.. so can u please stop bashing bush for "knowing" about the 911 terrorist attacks?

Well finally att is doing something good. I have a thunderbolt and I live in los Angeles which has Verizon Lte. And will supposedly be getting att Lte in july. If atts Lte really is that fast I might consider switching.and get that htc holiday phone that will have att lte support. I like Verizon an all cuz Verizon lte is super fast and all but the only downer is that once u out of the lte area u fall back on slow ass evdo Rev. A. And I hate it cuz its slow and its da truth u guys kno that. U cannot even use voice and data at da same time. I hate it when that happens. And i read somewhere else that with atts lte phones once u out of the lte area that ur phone will fall back to atts hspa+ running at 14.4 mbps. That sounds pretty good. Cuz its faster than Verizon's 3g. And u can still use voice and data at the same time.

@ the girl above me that lives in La. I kno what u mean I also live in La and have a Droid charge. Great phone.. and all when it has a 4g signal. But many places in La are still 3g only. When my phone drops to 3g I've done speed tests and I never get more than 1mbp If I get 2 its a really good day. My friend on his att atrix now that he fixed da upload speed. He always leaves me in the dust when my phone is on 3g. He usually gets 3-5 mbps up and down. When I'm in a 4g area obviously I get faster speeds than him. So I kno it sucks when the phone falls back to evdo Rev A. And if at&ts Lte phones are gunna fall back on hspa+ then that's gunna be coo people with those phones won't really notice a difference in speed. Like us people on Verizon ..cuz they will still be getting fast speeds. Unlike us that have to stick with slow evdo Rev A.

B_LL SH_T. I Bet they used it near a cell tower out in the open. These arent real speeds! Just wait for 25 million customers to use it and see speeds drop like verizon who had 21 mbps and went down to 15 in about 2 months.

can someone explain to me how this is faster than tmobile's 42mb/s HSPA+ network thats also on a 84mb/s upgrade path by next year?!?
I realize LTE is better on bandwith but it seems like ATT is taking a step backwards by buying Tmobile, dismantling it, and installing a slower network (for at least the next 5 years i bet) in its place.. just to have the same "tech" as VZW.

ATT is not going to get rid of T-mobile's super fast 4g, (it would be plain stupid) ATT is stupid but not that much. They are going to take T-mobiles 1800mhz spectrum and there 700Mhz spectrum, so ATT gets same speeds as T-mobile. Plus there 4g network will be almost as big as there 3g network.
