KIRKLAND, Wash. -- Clearwire Corporation (www.clearwire.com) -- a provider of next-generation wireless Internet services enabling fast, simple, portable and reliable communications anytime and anywhere within Clearwire's coverage area -- announced today it has officially launched its service in Seattle, Everett, Tacoma and surrounding areas. More than two million people in the greater Seattle area are now eligible to subscribe for Clearwire's service.

"Clearwire's wireless technology can help users realize more freedom and the potential of the Internet," said Craig McCaw, chairman and co-CEO of Clearwire. "Our goal has always been to look at the wants and needs that people have in ways the major carriers didn't have interest or time to pursue. Clearwire is delivering on this goal by providing services that are differentiated from everything else that is currently available. We are seeing the same phenomenon today that we saw in cellular more than 20 years ago -- people like the idea of not being tied to a specific location by a cable in order to communicate and access information."

"The Seattle, Tacoma and Everett deployments constitute Clearwire's largest market to date, making our services available now to more than eight million people in more than 360 cities and towns across the United States," said Ben Wolff, co-CEO and co-president of Clearwire. "We are changing the way people access all the Internet has to offer by delivering services that are fast, simple, portable, reliable and affordable. No other service provides all of these benefits in one package the way we do."

Clearwire provides an easy off-the-shelf wireless high-speed Internet solution. Customers typically have the service operating within minutes of receiving the modem without any need for a technician to visit. There is no software to load and generally no configuring or changes to the customer's computer. The fast and simple service can be accessed by simply taking the modem out of the box, plugging it in and connecting the Ethernet cord to the customer's computer. With users such as real estate professionals, contractors, students, home-based educators, public safety organizations and families, Clearwire's simple and portable service enables customers to access the Internet in creative and unexpected ways.

"With Clearwire's service, we constantly see our customers redefine how they live and work," said Perry Satterlee, Clearwire's co-president. "We see customers invent new solutions and use Clearwire in ways which allow them to truly experience the Internet on their terms."

Consistent with Clearwire's efforts to support the communities in which it operates, today's launch is coupled with Clearwire's announcement that it is working with local organizations to contribute its services to address the educational and communications needs of young people located in the Seattle, Tacoma and Everett communities in new and unique ways.

The company announced its "Clearly Connected Communities" initiative through which it will provide its simple and portable Internet service to community organizations assisting foster care, homeless and seriously ill children. The goal of Clearwire's initiative is to provide a means for children and teens to make meaningful connections with friends and loved ones and to take advantage of learning opportunities and entertainment that would not otherwise be available -- breaking the barriers resulting from isolation or limited resources. Clearwire plans to work with several local organizations, which initially include: Starlight Starbright Children's Foundation (www.starlight-washington.org), 826 Seattle (www.826seattle.org), Team Read (www.teamread.com), and the Mockingbird Society (www.mockingbirdsociety.org). "We want to make a difference and apply our technology and services in ways that are important to the greater Seattle community," said McCaw.

Clearwire will celebrate the launch of its service in the greater Seattle area by presenting a laser light show tonight at the Seattle Space Needle. The first of its kind for the iconic Seattle landmark, the laser light show promises to be the largest in the city's history.

Customers can sign up for the Clearwire service by calling 1-888-CLEARWIRE or going to www.clearwire.com. In addition, customers can buy Clearwire at Best Buy stores, located in each of the Clearwire markets, as well as Clearwire authorized representatives, Clearwire retail locations and mall kiosks.
