Clearwire Adds 10 More Markets September First

Clearwire announced the official launch day of
CLEAR 4G service in Boise, Idaho; Bellingham, Wash.; and eight markets
throughout Texas, including: Abilene, Amarillo, Corpus Christi, Lubbock,
Midland/Odessa, Killeen/Temple, Waco and Wichita Falls will occur on
September 1, 2009.

Clearwire will celebrate the official launches in each market with local
events, retail store openings, ad campaigns and promotional offers
throughout the fall.

CLEAR offers the first mobile Internet service that works as
fast on the go as it does at home. Unlike other wireless services, CLEAR
delivers a mobile broadband internet experience on par with speeds
typically experienced only on wired connections, like DSL.

The CLEAR customer experience is similar to that provided by Wi-Fi, but
without the short range limitations of a traditional hot spot. CLEAR
uses a 4G technology that differs from Wi-Fi called WiMAX, which
provides service areas measured in miles, not feet.

Clearwire's 4G network is now available in four markets, with the
expected September 1^st launches adding an additional 10
markets, and the company plans to bring CLEAR to 80 markets covering up
to 120 million people by the end of 2010. In addition to the markets
announced today, consumers and businesses can now purchase the company's
4G services online and at various retail locations in Atlanta;
Baltimore; Las Vegas and Portland, Oregon.

Some of the additional markets planned to launch in 2009 include
Chicago, Charlotte, Dallas/Ft. Worth, Honolulu, Philadelphia and
Seattle. In 2010, Clearwire plans to launch 4G service in New York,
Boston, Washington, D.C., Houston and the San Francisco Bay Area among
others.
