Sierra Wireless collaborates with Telefónica HSPA+ demonstration at Mobile World Congress

Telefónica utilizes the new Sierra Wireless USB 306 to demonstrate the breakthrough speed of HSPA+ mobile broadband technology

BARCELONA, Spain – Sierra Wireless (NASDAQ: SWIR - TSX: SW) today announced the company is collaborating with Telefónica to demonstrate HSPA+ mobile broadband network technology at Mobile World Congress, currently underway in Barcelona until February 19. Telefónica is hosting the demonstration at the company’s booth, using the new Sierra Wireless USB 306.

HSPA+ network technology significantly increases mobile broadband data speeds, reduces latency, boosts network capacity, and provides a better user experience. The higher bandwidth supports the more data-intensive applications people commonly use on the Internet today, including video and music downloads.

“HSPA+ is a significant step forward for mobile broadband technology that provides people with faster, full access to their favorite social networking and online applications wherever they go,” said Jim Lahey, vice president, EMEA, for Sierra Wireless. “Sierra Wireless and Telefónica have worked together many times over the years to improve the user experience for mobile broadband customers, and we’re pleased to have the opportunity to continue this collaboration. This demonstration is a great opportunity for people to see where mobile broadband technology is going next.”
