Sequans' LTE Technology Approved by China's MIIT

Approval qualifies Sequans to participate in large scale LTE trials of China Mobile

PARIS, France – September 14, 2011 –Sequans Communications S.A. (NYSE: SQNS) announced that its LTE semiconductor technology has been officially approved by China’s Ministry of Industry and Information Technology (MIIT), a government entity responsible for the regulation and development of China’s wireless industry. The approval signifies that Sequans’ technology is qualified for use in LTE networks in China.

Sequans’ LTE semiconductor solution has been undergoing testing for several months while interoperating with leading system vendors Huawei, and Alcatel-Lucent Shanghai Bell (Alcatel-Lucent’s Chinese subsidiary). The successful passing of the tests indicates that Sequans’ technology supports the MIIT performance and interoperability requirements necessary for the technology to be used in the field.

“We are very pleased to have the MIIT stamp of approval which we believe signals our readiness for worldwide deployment,” said Georges Karam, Sequans CEO. “We have been working toward this ever since China Mobile asked us to provide technology for their first TD-LTE demonstration network at the World Expo 2010 in Shanghai, and we look forward to participating in the large scale trials and future commercial deployments of China Mobile and other LTE operators who now have confirmation of the maturity of Sequans’ LTE solutions.”

The MIIT performance and interoperability testing was conducted in both the 2.3 and 2.6 GHz bands. The chip used in the tests was Sequans’ SQN3010 TD-LTE baseband chip. In addition to Alcatel-Lucent, and Huawei, Sequans has completed LTE interoperability testing on a private basis with Ericsson, Nokia Siemens Networks, ZTE and other network vendors.

The approval by the MIIT of Sequans’ SQN3010 solution follows the chip’s recent selection by NetComm, a device maker that recently announced it had been selected to provide TD-LTE devices for a major national LTE network in Australia.
