The Clearwire pc card Brings "True Broadband"[TM] Experience to People on the Go

KIRKLAND, Wash. -- Clearwire Corporation (NASDAQ:CLWR) announced today the availability of the first Clearwire pc card through all of its distribution channels in its markets across the United States. Based on Clearwire's guiding principles of simplicity, reliability, high speed and affordability the Clearwire pc card delivers a "True Broadband"[TM] experience unlike any other pc card available in the market place today.

"Building on the success of our residential broadband services, the Clearwire pc card offers consumers, business and enterprise customers the ability to experience all that the Internet has to offer while they are on the go anywhere within our coverage area," said Ben Wolff, Clearwire chief executive officer. "As our coverage area continues to expand, the Clearwire pc card is ideal for the majority of the population that spends most of their time in their local communities. Utilizing Motorola's pre-WiMAX OFDM technology coupled with more total spectrum devoted solely to data services in the markets in which we operate than any other carrier in the US enables the Clearwire pc card to deliver a unique user experience."

The Clearwire pc card expands the company's product portfolio to provide a personal broadband experience with greater portability through a smaller device, requiring only the power provided by the customer's laptop or notebook computer. Utilizing Clearwire's own broadband wireless network, the Clearwire pc card is designed to provide consumers a consistent user experience of up to 1.5 Mbps resulting in a smooth, seamless, robust Internet experience.

The Clearwire pc card is currently available in all Clearwire markets nationwide through Clearwire retail locations, as well with the company's authorized local retailers and national partners, Best Buy and Circuit City.
