HOUSTON--(EON: Enhanced Online News)--Clearwire Communications, LLC, an operating subsidiary of Clearwire Corporation (NASDAQ: CLWR) announced today the expansion of its sales operations for CLEAR’s super fast mobile Internet service throughout greater Houston. The company also named John Smith as general manager for the Houston market.

“We're pleased to complete our Texas service launch with a valuable new category of Internet service designed to make people’s lives more enjoyable and more productive.”

With CLEAR, consumers and businesses can access the Internet wirelessly, at true broadband speeds – at home, in the office, and on the go anywhere in the CLEAR coverage area. CLEAR covers more than 1,900 square miles and more than 4 million people. Regionally, service extends as far north as Conroe and northeast as Kingwood; as far west as Katy and southwest as Richmond/Rosenburg; as far south as Alvin and southeast as Clear Lake; as far east as Baytown. CLEAR will also cover Lake Jackson.

“CLEAR is thrilled to bring to Houston residents, businesses and visitors an Internet experience similar to what they’re used to having at home or the office, anywhere around town or on the go,” said John Smith, Clearwire general manager, Houston. “We're pleased to complete our Texas service launch with a valuable new category of Internet service designed to make people’s lives more enjoyable and more productive.”

A CLEAR Difference

The CLEAR customer experience is similar to that provided by Wi-Fi, but without the short-range limitations of a traditional Internet hotspot. CLEAR uses a wireless 4G technology that differs from Wi-Fi called WiMAX, which provides service areas measured in miles, not feet. Furthermore, CLEAR gives users average mobile download speeds of 3 to 6 mbps with bursts over 10 mbps.*

As the Internet integrates deeper into daily life, the opportunities to stay connected and be productive are enhanced by CLEAR in numerous ways. For example:

• A mobile professional no longer needs to seek out Wi-Fi hotspots or be constrained by the speeds and limitations of 3G modem cards;
• A college student or retiree can now have affordable Internet service to meet their needs at home, on campus and on-the-go;
• A commuter can now work or access entertainment sites like Hulu or Pandora on the way to and from home;
• A busy parent can now have full Internet connectivity for kids studying or playing games in the back of the family minivan.

For these and many other customers, CLEAR’s simple and innovative pricing provides ultimate flexibility. CLEAR’s mobile and residential plans can be purchased by the day or by the month, with several no-service-contract options available. Home Internet service plans start at $30 (USD) per month. CLEAR 4G mobile Internet plans start at $40 per month. For a limited time, customers in Houston can take advantage of CLEAR’s online-only mobile Internet promotion with plans starting at $15 per month for the first two months after a $50 service credit with a two-year service agreement. This online promotion is available at www.clear.com.

Additional savings are available for customers purchasing a combination of services such as home-and-mobile or mobile-and-mobile options. Combination plans start at $55 per month.

True road warriors will benefit from the speed and reach of the CLEAR 4G+ dual-mode 4G/3G service. CLEAR 4G+ offers customers access to the entire Clearwire 4G network and 3G mobile Internet service outside the CLEAR service area. CLEAR 4G+ is available for $55 per month.

Visitors or occasional users with a WiMAX-enabled device can also purchase a convenient day pass for $10.

Full details about CLEAR products, service plans and options for business customers can be found online at www.clear.com, at a CLEAR retail store, or by visiting an authorized CLEAR dealer. CLEAR retail stores in Houston are located at: First Colony Mall, Kay Mills Mall, Willowbrook Mall, The Woodlands Mall and Baybrook Mall. Additional stores will open later this spring at the Galleria and Memorial City Mall.

CLEAR service is also available from a number of other outlets including Best Buy, Frys, MicroCenter and RadioShack.

Simply Plug-In and Go

CLEAR offers several simple choices for broadband connectivity.

• Clear USB Modem and Clear 4G+ Mobile: Mobile users simply plug-in CLEAR’s compact, mobile WiMAX-enabled USB modem into their laptop to get online. From Ubee, the USB modem is available for only $64.99 or leased for just $3.99 per month. Customers can purchase the modem from a store or online. Customers who travel across the U.S. may purchase the Clear 4G+ mobile USB, a dual-mode (4G/3G) modem from CLEAR. The dual-mode capabilities give the truly mobile user access to nationwide 3G network service whenever the CLEAR 4G service is not available. The 4G+ mobile USB is available to lease for only $5.99 per month.
• Residential Data & Voice Services: For residential service, CLEAR offers customers a wireless high-speed modem, about the size of a small book. Customers simply plug the modem into a power outlet anywhere in their home or office and connect the modem to their PC or wireless router. This enables consumers and businesses to install high-speed Internet service without the need to schedule an appointment, drill holes in their walls, or otherwise disrupt their day. The Clear Home Modem Series G, a residential modem from Gemtek, can be purchased for $79.99 or leased for just $4.99 monthly. Residential customers can also add in-home voice service with purchase of the Clear Voice Adapter. There are 3 packages to choose from – Basic Home Clear Internet with Voice, Get Two, or Get Three - all with flat monthly rates.
• Clear Spot: With the Clear Spot, any existing, off-the-shelf Wi-Fi device (compatible with 802.11b/g) can connect to CLEAR’s mobile WiMAX network. The Clear Spot creates a personal Wi-Fi hotspot that travels with consumers anywhere they happen to be within CLEAR’s mobile WiMAX service area. This $139.99 device is a portable, battery-powered router that seamlessly connects up to eight standard Wi-Fi-enabled devices (computers, mobile phones, portable gaming, consoles, cameras, etc.) to the Internet via a Clear USB modem to access CLEAR’s mobile WiMAX network. The Clear Spot is compatible with both the Clear 4G and Clear 4G+ mobile USB dual-mode service options.
• Intel Embedded WiMAX Laptops: On April 1, the Dell Inspiron Mini 10 netbook featuring the Intel® Atom™ processor N450 with embedded 4G technology will be available for customers through select CLEAR retail locations, telesales and www.clear.com. This addition will further extend the company’s leadership in 4G mobile computing.

Forward-Looking Statements

This release, and other written and oral statements made by Clearwire from time to time, contains forward-looking statements which are based on management's current expectations and beliefs, as well as on a number of assumptions concerning future events made with information that is currently available. Forward-looking statements may include, without limitation, management's expectations regarding future financial and operating performance and financial condition; proposed transactions; network development and market launch plans; strategic plans and objectives; industry conditions; the strength of the balance sheet; and liquidity and financing needs. The words "will," "would," "may," "should," "estimate," "project," "forecast," "intend," "expect," "believe," "target," "designed," "plan" and similar expressions are intended to identify forward-looking statements. Readers are cautioned not to put undue reliance on such forward- looking statements, which are not a guarantee of performance and are subject to a number of uncertainties and other factors, many of which are outside of Clearwire's control, which could cause actual results to differ materially and adversely from such statements. Some factors that could cause actual results to differ are:

We are an early-stage company with a history of operating losses and we expect to continue to realize significant net losses for the foreseeable future.

Our current and future plans are subject to a number of conditions and uncertainties, including among others, our ability to manage ongoing market development activities (including the development of over 10,000 sites), our performance in launched markets and our access to additional funding.

We regularly evaluate our plans, and we may elect to pursue new or alternative strategies which we believe would be beneficial to our business, including among other things, modifying the pace at which we build our 4G mobile broadband networks, augmenting our network coverage in markets we launch, changing our sales and marketing strategy and or acquiring additional spectrum.

If our business fails to perform as we expect, or if we elect to pursue new plans or strategies, we may be required to raise substantial additional financing, and if we are unable to raise such financing on acceptable terms we may need to modify our plans accordingly.

We may fail to realize all of the anticipated benefits of the transactions with Sprint and the strategic investors.

We are committed to using commercially reasonable efforts to deploy wireless broadband networks based solely on mobile WiMAX technology, even if there are alternative technologies available in the future that are technologically superior or more cost effective.

We currently depend on our commercial partners to develop and deliver the equipment for our legacy and mobile WiMAX networks.

Many of our competitors are better established and have significantly greater resources, and may subsidize their competitive offerings with other products and services.

Our substantial indebtedness and restrictive debt covenants could limit our financing options and liquidity position and may limit our ability to grow our business.

Sprint Nextel Corporation owns a majority of our shares, resulting in Sprint holding a majority voting interest in the Company, and Sprint may have, or may develop in the future, interests that may diverge from other stockholders.

Future sales of large blocks of our common stock may adversely impact our stock price. For a more detailed description of the factors that could cause such a difference, please refer to Clearwire's filings with the Securities and Exchange Commission, including the information under the heading "Risk Factors" in our Annual Report on Form 10-K filed on February 24, 2010. Clearwire assumes no obligation to update or supplement such forward-looking statements.
