Sequans and Clearwire to Collaborate on TDD-LTE Ecosystem Development

Companies to Work Closely on Performance Testing and Prototyping of TDD-LTE Devices

PARIS and BELLEVUE, Wash., May 7, 2012 (GLOBE NEWSWIRE) — 4G chipmaker Sequans Communications S.A. (NYSE:SQNS) and Clearwire (NASDAQ:CLWR, news, filings), a leading provider of wireless broadband services, today announced an agreement to collaborate on LTE for the purpose of accelerating the availability of LTE devices for Clearwire’s planned TDD-LTE network and to optimize the user experience for Clearwire’s customers. The two companies will work together on performance testing and certification, standards development, and the creation of devices to support multi-band, multi-mode TDD-LTE and FDD-LTE solutions.

“Clearwire is a 4G leader with big plans for TDD-LTE where it is establishing strategic partnerships around the world to develop and strengthen the TDD-LTE ecosystem,” said Georges Karam, Sequans CEO. “Continuing the successful relationship begun under their current 4G network configuration into TDD-LTE makes perfect sense for our two companies. We are very pleased to continue our collaboration with Clearwire.”

“As one of the largest chip providers for a wide range of devices in the WiMAX ecosystem, Sequans has been a major enabler of our growth,” said John Saw, Clearwire’s Chief Technology Officer. “We are pleased to work with Sequans to bring LTE devices to market while also ensuring that the user experience on our planned LTE Advanced-ready network is second to none. We look forward to leveraging our successful relationship with Sequans to develop a new wave of devices for our 4G future.”

Sequans TDD-LTE Leadership

Sequans is one of the early leaders in TDD-LTE chip technology and was one of the first to provide China Mobile with working silicon for the launch of the world’s first TDD-LTE demonstration network in Shanghai in May of 2010. Sequans’ technology was approved by China’s MIIT for use in China and was also used in one of six major commercial trials China Mobile has deployed. Sequans’ TDD-LTE technology is operating in commercial networks in Brazil and Australia.

Clearwire LTE and Band Class 41

Clearwire’s next-generation LTE Advanced-ready network will operate according to the 3GPP Band 41 specification, which aligns to Clearwire’s 2.6 GHz spectrum frequency. Clearwire’s LTE network is expected to be a major advancement over the current LTE networks deployed in the U.S. because it will be designed to provide far more broadband capacity than is possible with today’s other 4G networks. With more than 160MHz of spectrum available in the 100 largest markets in the U.S., Clearwire’s LTE Advanced-ready network should position the company as the clear leader in 4G mobile broadband technology, capable of serving the current and anticipated future demands of wholesale and retail customers.

Clearwire expects that multi-band, multi-mode TDD-LTE devices that can run on its network and other networks will be commercially available in 2013.
