Clearwire to Launch Innovation WiMAX Network to Silicon Valley Developers

- “WiMAX Innovation Network” to accelerate 4G mobile broadband development, initially covering more than 20 square miles

- Cisco, Google, Intel, and leading educational institution among first supporters

- Service will be provided free to qualified developers for one year

KIRKLAND, Wash.- Clearwire Corporation (NASDAQ: CLWR) today announced a major step toward application development for fourth-generation (4G) mobile internet with plans for a “WiMAX Innovation Network” in the heart of the high-tech industry in Silicon Valley, CA.

The WiMAX Innovation Network will initially cover more than 20 square miles in Silicon Valley and bring 4G wireless service to campuses of some of the world’s leading technology innovators including early participants Google Inc., Intel Corporation, and a leading educational institution in Silicon Valley. Cisco will provide core Internet Protocol Next-Generation Network (IP NGN) infrastructure equipment in support of the WiMAX Innovation Network. Service is expected to be available to developers by late summer of this year giving them a head start on commercial service launching in the Bay Area in 2010.

“The WiMAX Innovation Network will provide some of the world’s most talented developers with a live test environment in which to build broadband services specifically designed for the 4G mobile Internet experience,” said Scott Richardson, chief strategy officer for Clearwire. “Our goals have always been to change the way people access the Internet and provide new opportunities for mobile applications. Providing early access to an eager pool of developers while we continue to roll out 4G services nationally makes perfect sense.”

“The Cisco IP NGN architecture will play a key role in the WiMAX Innovation Network,” said Larry Lang, vice president and general manager of services and mobility business unit, Cisco. “An IP network is the platform to deliver on the promise of mobility and enable developers to create new services and applications. With an advanced Cisco IP NGN, these services can be unlocked to create revenue-generating offerings for service providers and a better, more tailored experience for the end user.”

“As we shift to an unwired, always connected Internet, new WiMAX-enabled notebooks and netbooks from Intel are available today that provide the power to deliver data-intensive applications and services on the go with new WIMAX networks,” said Sriram Viswanathan, vice president of Intel Capital and general manager of WiMAX Program Office, Intel. “We look forward to seeing what developers on this Innovation Network create to help accelerate and test the limits of WiMAX wireless broadband technology.”

“Enabling developers to start building the next generation of mobile applications on Clear’s 4G network now will encourage innovation and showcase the benefits of an open network,” said Larry Alder, mobile product manager at Google.

Service will be provided free to a limited number of qualified developers for one year. Clearwire will provide WiMAX USB Modems for $49.99. To qualify, developers must register for Clearwire’s developer program and describe the products or business ideas they wish to pursue.

In addition to the mobile WiMAX network in the Bay Area, Clearwire expects to launch its CLEARTM 4G mobile Internet service covering up to 120 million people in more than 80 cities in 2010, including cities such as Atlanta, Las Vegas, Baltimore, Chicago, Charlotte, Dallas/Ft. Worth, Honolulu, Philadelphia, and Seattle in 2009.
