• Clearwire's LTE Advanced-Ready Network to Offer Capacity Resources for Cricket's 4G Network
  • Agreement Will Supplement LTE Coverage that Cricket is Deploying Across its Own Networks

San Diego and Bellevue, Wash. - March 14, 2012 - Cricket Communications, Inc., a leading provider of innovative and value-driven wireless services, and Clearwire Corp (NADSAQ: CLWR) today announced that they have entered into a five-year wholesale agreement. With the agreement, Cricket will become the second operator signed on to leverage Clearwire's forthcoming LTE Advanced-ready network, which will provide capacity off-load services to supplement Cricket's own LTE network. Cricket currently plans to deploy LTE across approximately two-thirds of its current network footprint over the next two to three years and to cover up to approximately 25 million POPs with LTE network technology in 2012.

"The high-speed 4G LTE networks we are deploying will complement our current robust 3G network and allow us to continue innovating value for our Cricket customers," said Doug Hutcheson, President and CEO of Leap Wireless, Cricket's parent company. "We believe this agreement with Clearwire provides us with an attractive option to supplement our own LTE build-out strategy and gives us the flexibility to access additional 4G capacity where needed as data-centric devices continue to become more popular."

"The beginning of our long-term wholesale partnership with Cricket is a key step forward in the development of Clearwire's wholesale LTE business model," said Erik Prusch, President and CEO of Clearwire. "Not all LTE networks are created equally. We have always believed that our unmatched spectrum portfolio offers a compelling resource that can and will enable wireless operators to thrive in the 4G marketplace of the future. We are very pleased to provide Cricket with additional mobile broadband resources to supplement their own LTE build in order to deliver a robust 4G experience for their customers and we continue to actively seek new opportunities to serve the needs of other 4G providers."

Financial terms of the agreement were not disclosed.
