McCaw Led Clearwire Launches Commerical Wireless Broadband Services in Jacksonville

JACKSONVILLE, Fla. (Aug. 26, 2004) — Clearwire, a broadband services company led by wireless pioneer Craig McCaw, officially launched its wireless, high-speed broadband Internet service in Jacksonville today. Company and community leaders symbolically cut through a ribbon of coaxial cable and telephone cord in front of the new Main Library site in downtown Jacksonville.

The Kirkland, Wash.-based company drew national attention earlier this summer when it announced Jacksonville would be the first city in the U.S. to receive Clearwire’s service. The high-speed Internet service uses radio spectrum to provide service through a unique wireless modem plugged into the user’s computer instead of hooking up to traditional coaxial cable or telephone wires.

The launch of Clearwire is a culmination of more than two years of activity that has included the acquisition of several companies and the accumulation of licensed spectrum in markets throughout the United States.

“It is exciting to launch our commercial service in Jacksonville,” commented Perry Satterlee, Clearwire chief operating officer. “It is another important milestone that has been met as we continue our mission of providing a better broadband choice for consumers across America.”

The company’s wireless high-speed broadband Internet service is now available to over 120,000 homes in Jacksonville covering an area of over 100 square miles, The Clearwire service delivers up to 1.5 million bits per second (Mbps), which is comparable to DSL service and 25 times faster than typical dial-up connections.

The launch also included an innovative partnership with Jacksonville’s new Main Library. Clearwire will make its unique wireless modems available to be checked out, free of charge, to library patrons seeking Internet service.
