Sequans Delivers 150 Mbps Category 4 LTE Throughput

Achieved in 20 MHz FDD channel with H-ARQ and encryption enabled

PARIS — June 11, 2012 — 4G chipmaker Sequans Communications (NYSE: SQNS) has achieved full category 4 LTE downlink throughput of 150 Mbps—the maximum category 4 rate—during interoperability testing with several major eNodeB and test equipment vendors. The tests featured a Sequans-powered LTE USB dongle operating over a 20 MHz FDD channel, providing LTE connectivity between a laptop PC and an eNodeB or eNodeB simulator. The test configuration was in complete compliance with 3GPP specifications with all key Release 9 features activated, including H-ARQ recombining and encryption. This achievement shows that Sequans’ chip architecture has the headroom to deliver the industry’s highest LTE performance in a real world scenario.

“Sequans is one of the very few LTE chipmakers delivering category 4 throughput today and the only one I know to have achieved the full 150 Mbps.” said Georges Karam, Sequans CEO. “Furthermore, this performance was highly stable with the maximum throughput sustained throughout the testing period, showing that Sequans’ LTE chips are a cut above the rest and can deliver the fastest, most robust, and overall best-in-class LTE connectivity available today.”

The chip powering the USB dongle is the Sequans SQN3110, the baseband chip at the heart of Sequans’ second generation Andromeda LTE platform for mobile devices. It is built in 40 nm CMOS, is 3GPP R9 compliant, supports both TDD and FDD for global compatibility, and comes in a very small 10×10 mm package that includes SDRAM.

Sequans has conducted successful LTE interoperability testing with major eNodeB vendors Ericsson, Nokia Siemens, ZTE, Huawei, and Alcatel-Lucent, and leading test equipment vendors Rohde & Schwarz, Aeroflex, Agilent, and National Instruments. Sequans’ first generation LTE technology is operating in two commercial networks, and its second-generation LTE technology is in trial with major operators all over the world with commercial deployments imminent.

“Our years of experience in 4G, developing and delivering multiple generations of ever-advancing 4G technology, has led to the industry’s most efficient LTE chip design and maximum achievable throughput,” said Karam. “Operators with 20 MHz of spectrum who deploy Sequans’ superior technology will be able to benefit from the full performance of LTE, and will be able to give their users the industry’s most outstanding LTE experience.”
