In a press release today, Clearwire has announced their intent to add LTE Advanced capabilities to their existing network infrastructure.  LTE Advanced is true 4G technology as originally defined by the various groups that define such things, and this will be its first appearance.  The LTE Advanced tech standards call for peak download speeds over 100 Mbps, and Clearwire says their trials have exceeded 120 Mbps.  That's fast. 

Clearwire also is quick to mention that they are not abandoning their existing Wimax network or customers, and expect to gain over 2 million additional users throughout the rest of 2011. 

The big winner here looks to be Sprint, who already has a business arrangement with Clearwire and has announced a partnership with LightSquared to bring LTE to their customers.  Customers have 4G now with Wimax, "better" 4G later with LTE, and "real" 4G with LTE Advanced.  Sounds like someone has all their ducks in a row, let's hope it pans out.  Read the full press release after the break.

  • Company Will Leverage Deep Spectrum Resources and All-IP Network to Meet Long-Term Mobile Broadband Demands
  • Unmatched LTE Network Capable of Serving Current and Future Wholesale and Retail Customers
  • Initial LTE Rollout Will Target High-Demand Areas of Current 4G Markets, Leverage Existing 4G Infrastructure for Minimal Capital Expense
  • Download Speeds Exceed 120 Mbps in Successful Network Technology Trial
  • Support for WiMAX 4G Network Technology to Continue

KIRKLAND, Wash, Aug. 3, 2011 (GLOBE NEWSWIRE) -- Clearwire Corporation (Nasdaq:CLWR), a leading provider of 4G wireless broadband services in the United States, today announced its intent to add "LTE Advanced-ready" technology to its 4G network. The announcement follows the successful completion of 4G technology trials that achieved download speeds exceeding 120 Mbps and demonstrated the potential of Clearwire's unmatched spectrum advantage.
The initial implementation of Clearwire's LTE network would target densely populated, urban areas of Clearwire's existing 4G markets where current 4G usage demands are high. The robust all-IP infrastructure already deployed in these markets can be leveraged to serve the company's LTE needs, delivering significant capital cost savings compared to a similar overlay by other carriers of an existing 3G architecture.
"Clearwire plans to raise the bar again for mobile broadband service in the United States," said John Stanton, Clearwire's Chairman and interim CEO. "Our leadership in launching 4G services forced a major change in the competitive mobile data landscape. Now, we plan to bring our considerable spectrum portfolio to bear to deliver an LTE network capable of meeting the future demands of the market."
"This is the future of mobile broadband," said Dr. John Saw, Clearwire's Chief Technology Officer. "Our extensive trial has clearly shown that our 'LTE Advanced-ready' network design, which leverages our deep spectrum with wide channels, can achieve far greater speeds and capacity than any other network that exists today. Clearwire is the only carrier with the unencumbered spectrum portfolio required to achieve this level of speed and capacity in the United States."
"In addition, the 2.5 GHz spectrum band in which we operate is widely allocated worldwide for 4G deployments, enabling a potentially robust, cost effective and global ecosystem that could serve billions of devices," Saw added. "We anticipate that the economies of scale derived from this global ecosystem will act as a catalyst for the development of thousands of low-cost devices and applications. And, since we currently support millions of customers in the 2.5 GHz band, we know that our LTE network won't present harmful interference issues with GPS or other sensitive spectrum bands."
Clearwire also noted that since launching its first 4G market in 2009, video has become the largest component of the company's overall data traffic and video traffic itself has increased more than tenfold since 2009. The company believes that as more video-intensive smartphones and services rise, so will the needs for Clearwire's high-capacity 4G wholesale network.
LTE Advanced is a 4G technical standard that calls for peak download mobile speeds of at least 100 Mbps, which far exceeds today's commercial networks. Clearwire's LTE network will be "LTE Advanced-ready" meaning that it will use an ultra-high-capacity spectrum configuration that is superior to the typical configuration of the slower, more capacity-constrained commercial LTE network designs in the United States of today.
Clearwire's LTE implementation plan, which is subject to additional funding, contemplates deploying Time Division Duplex (TDD) LTE technology and reusing its flexible all-IP network architecture and upgrading base station radios and some core network elements, which offers significant capital savings. This will include the use of multicarrier, or multichannel, wideband radios that will be carrier aggregation capable. Carrier aggregation is a key feature of LTE Advanced that will enable Clearwire to further leverage its vast spectrum depth to create larger "fat pipes" for deploying mobile broadband service. The network would position Clearwire as the clear leader in 4G mobile broadband technology, capable of serving the current and anticipated future demands of wholesale and retail customers.
Clearwire, together with some of the largest wireless carriers in the world, is a founding member of the Global TDD LTE Initiative (GTI) which aims to bring together leading industry partners to steer the TDD LTE ecosystem as a major standard in mobile broadband technology and drive the development of next generation mobile broadband networks. Member companies that currently support more than a billion subscribers on their networks believe that a global LTE standard has the potential to achieve significant economies of scale and serve hundreds of millions of customers worldwide.
Clearwire also restated its commitment to its existing 4G WiMAX network, which covers approximately 132 million people while serving 7.65 million retail and wholesale customers and an ecosystem of nearly 110 WiMAX enabled devices, including all 4G phones currently offered by Sprint. Clearwireexpects to end 2011 with approximately 10 million 4G customers.

Clearwire announces plans for LTE Advanced network, still committed to Wimax


Well lets not get ahead of ourselves. How about some 4G first as promised? As verizon BLOWS by sprint its pretty degrading having a 4G phone with no service in site. And im sure a lot of areas are in this situation. Verizon is adding 4G (LTE) to BOWLING GREEN OHIO. Are you joking!? and Sprint cant gets its crap together to encompass major cities.

Props to verizon to roll it out so quickly and blanket so many areas. Although I cant stomach their tiered data plans

(Detroit Suburbs)

Should of gotten verizon, I live 30 miles north of detroit and get 40 mbps down and 24 mbps up. But for $5 less a month on sprint I guess it's worth it for some people... Also I got in before the tiered data plans were put in place, so yep I've got unlimited data.

I hear ya...I'm also in the 'burbs of Detroit. I had been on Verizon up until Friday of last week and now I'm on Sprint (we changed providers at work). I went from a 3G phone (Droid Incredible) on a network with 4G coverage to a 4G phone (EVO 3D) on a network with only 3G coverage...WTF!!!!

Bottom line is I feel your pain and frustration. LOL

Nope:( LTE radios are different from 4G radios. So sprint will need to come out with LTE enabled phones with the correct hardware. Probably not for a while

what is the point of 120 mbps down if half the country doesn't even have 3g yet?

I live in one of the most highly populated areas of vermont (not a huge state, but 3g has been around for MANY years now) and i can still only get 2 mbps down, and that is only in a few spots.

hell, there isn't even 2g in some spots!

I just hope sprint is smart enough to put these two services on the same frequency for greater footprint.

That would be stupid of them, the frequency of WiMAX is the whole reason why it sucks so hard.

It's too high to penetrate thru building walls. You have to be near a window or outside unless you are real close to a tower to even get a good 4G signal.

If Sprint REALLY were smart, they would have never wasted time with WiMAX to begin with & started investing in a good LTE network to begin with instead of rushing out the door with WiMAX just to have the first "4G" because all it did was set them behind the competition to get GOOD 4G.

"They're beginning the transition...."

That's my whole point. They are the #3 carrier (in terms of subscribers) & just now starting while the #1 carrier, who may have been last to get "4G" rolled out, took their time & rolled out LTE from the get go. Sprint & AT&T went with WiMAX & "HSPA+ with advanced backhaul", respectively. They are now playing catch up & getting their own LTE plan in order a year later.

This guy (El Jefe) is always bad mouthing Sprint. I see him trolling the threads all the time. Dude, who the F cares if Sprint is #3 as far as subscribers go? By the time ATT&T (Tmo included) launch their LTE, so will Sprint with the addition of having WiMax. That my friend, will be cutting edge and will offer more to customers. I came from AT&T and there wasn't a single thing I liked about their coverage. I refused to go to Verizon because I saw what my friends were getting for $10-15/mo more...and now that they have tierd data because they were first to offer LTE (and charging an arm & leg for it)...PFFT! Funny how you can't even turn off your LTE radio as it rapes your battery and you're focred to charge it every 4 hours. You can have your LTE.

And who the hell cares about who the first company was to get LTE. True 4G is LTE Advanced and by the time Verizon or ATT&T get around to that, Sprint will be in the game already as well.

Keep hittin' that big red kool-aid.


well said my friend...and needed to be said. I dont understand why people always look for something negative to say on a post that is good news.

Freeing up the 800mhz band isn't for 4G usage. Sprint's moving their CDMA service there from 1900mhz, using CDMA 1X Advance. Sprint doesn't have enough bandwidth at 800mhz for LTE.

BTW, it looks like Sprint will never own their own 4G network.. Looks like all they will ever do is resell Clearwire and, one day, LightSquare.

I heard that sprint might end up getting rid of their iden network from Nextel. This would open up the 800mhz for sprint to use for 4g LTE. The 800mhz would be great on 4G also seeing how it can go through walls, something that WiMax fails so hard with.

Sprint is definitely in the money on this...

In fact, I have yet to hear any bad news come out of Sprint lately. That's a good sign and a definite sign that it's a great time to be a Sprint customer.


And it just so happens, the EvO3D has the 800mhz CDMA ESMR band included. hMMMmm I wonder why the Photon doesn't have it and wonder even more if the GS2 eRrr Epic Touch 4G will have it??

This is awesome news, though it won't actually matter for at least a year probably, but exciting none the less. I'm a happy sprint customer, especially if they get there LTE advanced network going decently soon. REAL 4g would be nice

These advanced networks really need to start getting voice services going on them so phones can disable older radios/network connections when not in use. The batteries are too taxed to make it half a day at this point.

This is great news for Sprint! I am very satisfied with their coverage and I travel all over this country. Its funny because my company phone is Verizon and there are so many times I have to pull my Evo out and finish the conversation. I almost have my company convinced to jump over to Sprint....better phones and a heck of a lot cheaper than Verizon and AT&T.

I couldn't have said it better myself. I live in Los Angeles and roam around LA County and the difference between AT&T's coverage and Sprint's coverage is night and day. I couldn't be happier. In fact, I plan on celebrating on Decemeber 19 because that's my 1 year mark with flipping the bird to AT&T and moving over to Sprint.

I save $20/mo. with Sprint compared to the plan I had with AT&T.

Sprint is also announcing something this fall about their network coverage, something about it all becoming 'clear', so if this is part of it combined with lightsquared; sprint is going to get good.

I couldn't be happier to see that Sprint is continuing to work to expand their coverage and compiling a decent LTE network. The announcment last week with light squared and now with clearwire only means that things are on the up & up and that Sprint customers will have CDMA 3G, WiMax and LTE. I'm stoked!

I certainly hope they don't have to move to tiered data like some of those other companies do *cough cough*

Hopefully this means they are headed in the right direction and won't have to do that (tiered data). Can't wait to see what's up ahead in the coming year!

Wait for it......The Evo 5G. Because the speed standard will have to be changed for marketing....again

Clear better get it's shit together, I haven't experienced it's mobile coverage yet, but I have home service and the infrastructure cannot handle the amount of people.

For now ... THIS IS ALL HYPE!!

Sprint and Clearwire are both bleeding cash still and the way the economy is, who's going to pump more money into them? All these new networks and upgrades take CASH!! Verizon has it, AT&T has it... Sprint and Clearwire are cash poor but they both keep talking about upgrading this and that...

I won't believe it till I see it.

BTW, look at WiMax as an example. Remember how much hype there was about Sprint's 4G ... eventual coverage and speed? Yeah... Coverage in areas they say has coverage is only good when outside and average speeds can't even match TMo's HSPA+, on a consistent bases, let alone get speeds or coverage like Verizon's LTE service..

I need to see action!!
