    Clearwire vs "Clear"

    Keep in mind there are two different consumer entities until all of the old Clearwire hardware is fully converted to current WiMAX standards.

    Often times over in the Sprint 4G WiMAX subforum, many question the small markets launched prior to the much bigger ones. The answer is very very simple actually. Those small markets have been around for several years now, they are simply being converted to current 4G WiMAX standards (IEEE 802.16e) and are still being converted. These are old Clearwire markets that are now new Clear 4G markets. These are often times smaller under served markets.




    The remaining 3G "Pre-WiMAX" markets scheduled to be completed by the end of the year:

    Worldwide Interoperability for Microwave Access (WiMAX)

    How WiMAX Works
    (courtesy Intel Corp. & Marshall Brain, Ed Grabianowski, Sam Churchill)

    In practical terms, WiMAX would operate similar to WiFi but at higher speeds, over greater distances and for a greater number of users. WiMAX could potentially erase the suburban and rural blackout areas that currently have no broadband Internet access because phone and cable companies have not yet run the necessary wires to those remote locations.

    A WiMAX system consists of two parts:

    - A WiMAX tower, similar in concept to a cell-phone tower - can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations.

    - A WiMAX receiver - The receiver and antenna could be a small box or PCMCIA card, or they could be built into a laptop the way WiFi access is today.

    A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). It can also connect to another WiMAX tower using a line-of-sight, microwave link(often referred to as a backhaul) is what allows WiMAX to provide coverage to remote rural areas.



    What this points out is that WiMAX actually can provide two forms of wireless service:

    There is the non-line-of-sight, WiFi sort of service, where a small antenna on your computer connects to the tower. In this mode, WiMAX uses a lower frequency range -- 2 GHz to 11 GHz (similar to WiFi). Lower-wavelength transmissions are not as easily disrupted by physical obstructions -- they are better able to diffract, or bend, around obstacles.

    There is line-of-sight service, where a fixed dish antenna points straight at the WiMAX tower from a rooftop or pole. The line-of-sight connection is stronger and more stable, so it's able to send a lot of data with fewer errors. Line-of-sight transmissions use higher frequencies, with ranges reaching a possible 66 GHz. At higher frequencies, there is less interference and lots more bandwidth. Example video found here Towerstream located in NYC.

    WiMAX IEEE 802.16



    There has been little word of any upgrade from the current 802.16e standard to "Rev2". The focus is the move to 802.16m standard or true "4G", which would be a substantial upgrade. Other WiMAX network hardware upgrades occur as technology evolves.
    Example 1 Example 2

    802.16m = 4x faster than 802.16e

    802.16m or "WiMAX 2.0" is currently under testing as we speak. Samsung said it plans to trial Release 2 via Clearwire in the United States and UQ Communications in Japan by late 2010. Yota also plans to put the first WiMax 2.0 units into service by the end of this year(2010), although The WiMAX Forum expects to see WiMAX Release 2 available commercially in the 2011-2012 timeframe.

    Samsung and Yota are now testing Mobile WiMAX 2.0 (IEEE 802.16m). Its data transfer speed is four times faster than current Mobile WiMAX (802.16e) networks, thanks to MIMO antenna technology, which also improves spectral efficiency, and other enhancements.

    By using 4X2 MIMO in an urban microcell, and 20 MHz TDD channel (double the usual 10 MHz), the 802.16m system can support both a 120 Mbit/s downlink and 60 Mbit/s uplink per site simultaneously, says the WiMAX Forum.

    Mobile WiMAX Release 2 provides strong backward compatibility with Release 1 solutions. It allows current Mobile WiMAX operators to migrate their Release 1 solutions to Release 2 by upgrading channel cards or software on their systems. Also, the subscribers who use currently available Mobile WiMAX devices can communicate with new Mobile WiMAX Release 2 systems without difficulty.

    4G systems, like Mobile WiMAX and LTE, will require 100-180 Mbps per sector, or close to 500 Mbps per tower. Clearwire CTO John Saw says microwave is critical. He estimates that 90 percent of the firm’s network uses the radio backhaul systems. DragonWave is the dominant supplier for Clearwire’s microwave backhaul network. AT&T and Verizon, which often monopolize fiber access in smaller communities, charge Sprint and Clearwire high rates to lease their fiber. But even with alot of "backhaul" a provider must have spectrum to deliver it or quality and performance suffers greatly. Spectrum is something Sprint and Clear have an abundance of in the U.S.

    Strategic Investors and Key Partners (streaming)

    Top executives from Sprint, Cisco, Google, Comcast, Intel, Time Warner Cable and Bright House Networks sound off about Clearwire, WiMAX, and the future of the mobile internet.

    __________________________________________________ _____________

    Here at Sidecut Reports we always thought the woe-is-Clearwire views were short-sighted, and thought such opinions ignored the company’s biggest asset, its huge chunk of wireless spectrum in the 2.5 GHz range. This spectrum has an interesting history — some was initially owned by Worldcom, which was then obtained by Nextel and then by Sprint through various mergers and deals — but it is now all under Clearwire’s purview, with total DEPTH of anywhere between 100 MHz and 150 MHz in most major U.S. markets.

    At the 700 MHz range, where AT&T and Verizon plan to deploy Long Term Evolution, the two big operators only have spectrum depth holdings of around 20 to 25 MHz each. As we’ve said before, this somewhat narrow depth of spectrum will initially mean LTE speeds far below the theoretical peak numbers that get tossed around in meaningless test situations.

    Why is the depth important? When it comes to wireless services, the depth of spectrum that you have dictates how wide a pipe you can offer customers — with more spectrum DEPTH you can have faster speeds, more customers, etc. Right now your iPhone 3G experience in many U.S. markets stinks in part because AT&T doesn’t have a lot of spectrum depth at the frequencies it is using, so in a simple sense the channels and towers get clogged up. Even the company’s spectrum holdings at 850 MHz, which it is touting as a “high quality” savior for 3G chokepoints, only total between 25 MHz and 50 MHz of depth in major markets, according to AT&T senior vice president Kris Rinne, who confirmed those totals in an interview last week. While that might be enough to let a few more iPhone calls go through, compared to Clearwire’s holdings it’s pretty thin gruel.

    Clearwire, on the other hand, has so much spectrum depth that it can deploy WiMAX today in big, thick channels while reserving enough spectrum depth to later deploy LTE if that makes sense, or perhaps now make some dough renting the spectrum to other players like T-Mobile. While spectrum alone won’t make WiMAX or Clearwire a successful business, we noted long ago that by itself the spectrum of the merged Clearwire-Sprint entity made the combination an even-money bet at worst. Now as other operators scramble to satisfy the growing need for mobile bandwidth, suddenly Craig McCaw’s latest spectrum play looks like a winning bet.

    Craig McCaw

    "Change occurs because there is a gap between what is and what should be"

    -Craig McCaw





    Who Craig McCaw is and what he has to do with Clearwire


    How Craig McCaw Built a 4G Network on the Cheap
    The mobile pioneer's Clearwire controls airwaves worth $20 billion or more
    By Gadi Dechter and Olga Kharif


    Craig McCaw's quest to dominate the emerging era of fourth generation, or 4G, wireless networks began in a Maryland basement office back in 2003. There, McCaw's representatives met with Rudy Geist, a lawyer with only one client, a Spanish-language broadcaster that happened to be the nation's largest licensee of the 2.5-gigahertz frequency of radio spectrum.

    That band had been given away to schools and nonprofits since the 1960s. In theory, it was to be used for educational TV. In practice, the spectrum mostly languished. McCaw signed a master lease with the Spanish broadcaster, giving a Kirkland (Wash.) company he founded that year called Clearwire a foothold in about 20 markets.

    Clearwire would end up with more than 1,000 such leases, for which it will pay about $5 billion over the next three decades. When the Federal Communications Commission in 2005 relaxed regulations on the 2.5-GHz band to encourage wireless broadband, its value exploded. McCaw was then in a position to compete against Sprint (S) and other companies for control of a national portfolio. In 2008 Sprint, which also had 2.5-GHz holdings—and was still struggling with its 2005 Nextel merger—folded its spectrum into Clearwire in exchange for a stake in the company.

    "That spectrum basically went from swampland to oceanfront property," says Brad Bowman, a community activist in Delray Beach, Fla., who advocates for municipalities to create their own 4G networks rather than rely on commercial carriers.

    Today, Clearwire says the airwaves it controls are worth $20 billion or more. Now we're about to find out whether McCaw, the mobile-phone pioneer who made a killing selling McCaw Cellular Communications to AT&T (T) for $11.5 billion in 1994 and later helped build Nextel, will rock the world of mobile communications once more. "Craig has the ability to bend the horizon," says Bob Ratliffe, a former senior vice-president at McCaw Cellular. "For a guy who isn't an electrical engineer, he's got an intuitive sense of where the spectrum will be valuable." (McCaw declined to be interviewed for this story.)

    Last year McCaw, who serves as Clearwire's chairman, hired former Vodafone (VOD) executive Bill Morrow to help him create a superfast wireless network that will serve all manner of devices—from smartphones to tablet computers to gadgets not yet invented—at speeds that rival some of the broadband connections now offered by cable and phone companies. Clearwire advertises 4G wireless as four times faster than 3G.

    It's safe to say Morrow hasn't had a boss quite like the 60-year-old McCaw before. Morrow sometimes finds himself summoned over to McCaw's office, where the billionaire holds forth with "philosopher-type views" on how to use the public's airwaves to "disrupt" entrenched telecommunications giants. "Next thing you know, I'm getting two or three books sent over as gifts to me," says Morrow.

    Yet Morrow wasn't signed on to be McCaw's literary pal. The two executives are trying to out-hustle far bigger rivals Verizon Wireless and AT&T, the two biggest carriers in the U.S., in a mobile data market that, by some projections, will reach $93 billion in revenue by 2013. Both AT&T and Verizon are planning to roll out 4G services over the next several years using a competing technology that could turn Clearwire's wireless broadband standard, called WiMAX, into the next Betamax. "I think we're in a better position," says AT&T spokesman Mark Siegel, calling Clearwire's technology "unproven for true mobility."

    While not a household name, Clearwire has two key advantages: McCaw's massive accumulation of relatively cheap broadband spectrum, which dwarfs the airwaves of AT&T or Verizon Wireless, and a one-year head start. Clearwire already offers 4G service under the Clear brand in 32 U.S. cities and plans to add up to 50 more by the end of 2010.

    To reach that number, the company is in the midst of a high-speed build-out. Last year the company put up 5,000 cell sites at a cost of $130,000 to $150,000 each. "That broke the record," says Morrow, 50. "This year we're doubling that in terms of the number of sites we're constructing." In 2010, Clearwire will spend up to $3.2 billion, the bulk of that on capital expenditures.

    Consider what's involved in putting up a single tower: leasing or buying real estate: winning community support and zoning permits, sometimes over fierce opposition; and paying as many as 25 workers to erect structures up to 400 feet high. The process takes from nine months to three years, says Dave Cloud, co-owner of NuHites Construction Services in Arkansas, which has installed equipment for Clearwire. "The task and the resources to do this build-out are enormous," says technology consultant Chetan Sharma. He figures Clearwire is putting up a tower an hour—including weekends.

    For Clearwire, much is riding on whether its strategy of buying up some 85 percent of the 2.5-GHz spectrum band will pay off. Some big tech players are clearly willing to bet sizable money on McCaw. Two years ago, Clearwire received $3.2 billion in investments from Comcast (CMSCSA), Intel (INTC) , Time Warner Cable (TWX), Google (GOOG), and Bright House Networks. Last year, Clearwire raised an additional $1.5 billion from a group led by Sprint Nextel (S]), prompting one Wall Street analyst to call the McCaw company "too strategic to fail." Sprint is now the majority shareholder of Clearwire and offers high-speed mobile Web service under the brand Sprint 4G. Sprint is releasing the first 4G smartphone in the U.S. on June 4.

    The $5 billion Clearwire will pay its license holders for its spectrum over the next three decades is a bargain compared to what its rivals are paying. (Clearwire's $20 billion valuation of its spectrum may prove to be conservative; J.H. Snider, president of policy think-tank iSolon.org and former research director at the New America Foundation's Wireless Future Program, puts the number closer to $50 billion.) AT&T and Verizon bought their spectrum that can be used for 4G at government auction in 2008, paying a combined $16 billion.

    AT&T and Verizon may have paid more, but those companies contend that their lower frequency, 700 megahertz, lets radio signals travel farther on less power and do a better job of penetrating buildings and other objects. "Clearwire will have to build two, three, maybe even four times the number of cell sites to get the same coverage," says Nicki Palmer, Verizon Wireless' vice-president for networks. Morrow disputes that assessment. In cities, where the bulk of customers are, he says, "you build the same amount of sites within a city whether you're on 700 MHz or 2.5 GHz."

    Even more pressing than the questions about coverage is the possibility that at its current rate of spending, Clearwire will burn through its cash in 2011, according to Steve Clement, an analyst at Pacific Crest Securities. Clearwire may need $3.8 billion more to reach its goal of building a network that covers 270 million people, Clement says.

    Then there's Clearwire's bet on WiMAX. Analysts increasingly see the technology backed by AT&T and Verizon Wireless, called LTE, for "long term evolution," as the industry standard. That could limit the number of cool new devices Clearwire and its reseller partners can offer customers and could ultimately force Morrow to convert the network to LTE at a cost of hundreds of millions of dollars. "It looks almost certain that Clearwire will move to LTE within a matter of 24 to 36 months," says Sharma, the technology consultant.

    Although Clearwire has never been profitable, it has about 1 million subscribers, double what it had a year ago. It added 283,000 net new subscribers in the first quarter, compared with 133,000 new customers in the previous quarter. "They're announcing nice growth in subscribers, but that growth is off of a very small base," said Jeff Belk, a San Diego-based telecom consultant and former Qualcomm executive. By comparison, Verizon Wireless alone has 93 million customers, all of whom the company will try to convert to its 4G service.

    However the 4G race shakes out, Clearwire can count on its "oceanfront" spectrum holdings to remain valuable even if the company's retail efforts fizzle. For example, consumer electronics companies have recently been expressing interest in including Clearwire's service with Internet-enabled devices like computer tablets, Morrow says.

    "A lot of spectrum is extremely valuable when you think about the exponential growth of mobile broadband data needs," says Sriram Viswanathan, an Intel vice-president and general manager of its WiMAX program. "Anyone that has more spectrum is going to be in a much better position." Or, as Belk puts it: "You can never be too rich, too thin, or have too much spectrum."

    The bottom line: Even if Clearwire's retail business sours, it will be able to resell 4G services to other carriers and device manufacturers.

    Clearwire U.S. Spectrum Holdings as of 2007 - pre Sprint merger

    *Sprint 2.5Ghz Holdings are not reflected





    Clearwire European Spectrum Holdings as of 2007





    Clearwire Sells Majority Stake In Irish WiMax Network

    Clearwire (NSDQ: CLWR) has sold off a majority of its assets in Ireland to Dublin-based Imagine Communications Group, freeing the company up to focus more on its rapid U.S. expansion. Financial terms of the deal were not disclosed, but Clearwire will become a minority shareholder.

    Ireland was one of Clearwire’s early markets where it built out 4G-like services; however, it’s more of a distraction than anything these days as Clearwire rushes to blanket the U.S. with high-speed wireless services ahead of the competition.

    Clearwire doesn’t break out specific numbers for its international markets, but it has the capacity to sign up about three million people in Belgium, Ireland and Spain, which is comparatively small to the 40-million plus it covers in the U.S. In those three countries, it has only 47,000 customers.

    Imagine said its purchase of Clearwire, including its assets and technical team, is part of a EUR100 million investment to provide high-speed wireless. With Clearwire’s spectrum holdings there, it now has over 120mHz of spectrum in the 3.4 and 3.6mHz bands.
