Sierra Wireless introduces the first 4G LTE module for Sprint

AirPrime® MC7355 augments existing portfolio of Sprint enabled modules, and Sierra Wireless continues to enhance and streamline certification processes through its CTIA authorized test laboratory

Vancouver, Canada - June 25, 2013 - Sierra Wireless (NASDAQ: SWIR) (TSX: SW) today announced that the AirPrime® MC7355 embedded module is now Sprint-certified - the first 4G LTE embedded wireless module to be certified on the Sprint network. Demonstrating technical leadership in the LTE space, the MC7355 joins a wide range of Sierra Wireless modules available for Sprint, rounding out a portfolio that includes the AirPrime SL909x (Multimode 3G/EV-DO) and the SL501x (EV-DO), with the SL301x (CDMA 1x) currently being verified for approval.

The AirPrime MC7355 is a PCI Express Mini Card module capable of delivering LTE data speeds up to 100 Mbps downlink and 50 Mbps uplink and is compatible with CDMA/EV-DO, HSPA+ and quad-band GSM/GPRS/EDGE. For OEM customers, Sierra Wireless is uniquely positioned to manage and facilitate Sprint certification through its CTIA authorized laboratory, thereby eliminating the need for a third-party lab and significantly reducing the time to market.

“As we continue to move forward with the rollout of our all-new network, a project known as Network Vision, the delivery of a world-class LTE network experience for our customers is paramount,” said Ben Vos, general manager-M2M, Sprint. “Sierra Wireless modules have a proven track record with Sprint and we look forward to now offering our OEM customers 4G LTE speeds utilizing a preferred supplier that can streamline the certification process for Sprint's customers and help them better achieve their individual business goals.”

“It's rewarding to reach a new milestone in what has been a long collaboration with Sprint - one where both companies are committed to stay at the forefront of M2M and 4G LTE technology,” said Dan Schieler, senior vice president, Worldwide Sales. “The MC7355 will allow our customers to leverage Sprint's 4G speeds and as the first LTE module supplier, and utilizing our CTIA authorized test facility, Sierra Wireless looks forward to continued collaboration that will directly benefit the operator's wireless M2M and PC OEM customers.”

Nationwide 4G LTE is a key element in Network Vision, Sprint's plan to consolidate multiple network technologies into one new, seamless network with the goal of increasing efficiency and enhancing network coverage, call quality and data speeds for customers across the United States. Sprint continues to be on schedule in rolling out 4G LTE nationwide, with service in 110 markets today and with sites on-air and implementation under way in hundreds more.
