Clearwire Enters Spain with the Launch of Its Wireless Internet Service in Seville.

Clearwire Connects Customers Instantly to the Internet with its Simple to Use and Portable Technology

SEVILLE, Spain -- Clearwire Espana S.A. (www.clearwire.es) today announced its first entry into Spain with the launch of its Instant Internet (Instanet) service in Seville. The Andalusian capital is the first market in Spain to launch Clearwire's (NASDAQ:CLWR) wireless Internet service providing an alternative to the traditional fixed ADSL and cable-based networks.

Clearwire connects customers using a non-line-of-sight wireless broadband network technology. Radio signals using a secure or licensed spectrum are transmitted from a tower to a small, wireless modem which easily connects a user's computer to the Internet. There is no software to download and generally no configuring or changes required to the customer's computer. Customers can be on the Internet within minutes of set-up.

Instanet offers users a reliable, instant, fast and simple Internet connection with the added ability to take it anywhere in Clearwire's coverage area whether it's at home, the office or the local coffee house. Clearwire's network in Seville covers more than 300,000 households.

"Seville's receptiveness to new technologies, and as the social and cultural nucleus in the south of the Peninsula made it an ideal first market for Clearwire's entry into Spain," said Gilberto Sanchez, Clearwire Espana general manager. "The more than 850,000 residents of Seville now have a better way to access the Internet immediately without the hassles or delays of traditional ADSL services. In addition, our customer care service operation is based in Seville to provide that high-touch customer experience."

"We continue to successfully expand our global footprint and are excited to offer our simple to use, instant, reliable and portable wireless broadband service in Spain," said Perry Satterlee, Clearwire chief operating officer and president. "Spain is the third country where we have launched service in Europe and together with our networks in Ireland and Belgium, Clearwire now covers more than 2.2 million people."

Customers can sign up for Clearwire's Instant Internet service at Airesur, Los Arcos, Nervion and Metromar shopping centers as well as with authorized retailers in Seville or by calling locally at 1422. For more information go to www.clearwire.es.
