Sierra Wireless congratulates M2M Value Chain Award Winners

Ecast and Renewable Energy Systems honored for innovative use of wireless data in machine-to-machine(M2M) applications
Vancouver, B.C.-June 22, 2007

Sierra Wireless (NASDAQ: SWIR - TSX: SW) is pleased to congratulate Ecast and Renewable Energy Systems for being honored with M2M Value Chain Awards, announced Wednesday night at the M2M United Conference in Chicago. The awards, sponsored by M2M magazine, honor successful corporate adopters of M2M technology and highlight the process of combining multiple technologies to create a winning solution.

“Both Ecast and Renewable Energy Systems offer great examples of the efficiencies that broadband wireless data connectivity can bring to M2M applications,” said Andy Berman, senior vice president of mobile and M2M for Sierra Wireless. “It’s a thrill to see them honored for their innovative applications, and we are pleased to have had the privilege of collaborating with each of these companies to make wireless data work for them.”

Both of the winning entries involve AirLink Raven modems, now a part of the Sierra Wireless Mobile & M2M product line. Powered by ALEOS, the longstanding benchmark for feature rich embedded intelligence, AirLink Raven modems provide an always on, always aware persistent wireless connection. Specifically designed for complex mobile data and remote asset management applications, they are ideal for a variety of applications, including telemetry, SCADA, intelligent transportation, utility management, remote monitoring, andsecurity.

Ecast: Music on demand
Ecast ( is the largest broadband touch-screen media network in the United States, delivering on-demand music, advertising, and other forms of entertainment to more than 10,000 digital jukeboxes in bars and nightclubs throughout the country. Each jukebox requires a continuous Internet connection to access Ecast’s online database of more than 200,000 songs. Using broadband landline connections proved to be cumbersome, often requiring long lead time for installation and limiting potential locations and relocations.

Using the AirLink Raven-E modem to provide wireless data connectivity, Ecast has reduced both the lead-time and the cost of installations, providing increased flexibility to choose the most profitable locations. In addition, Ecast is now able to consolidate new customers with a single Internet service provider, allowing the company to access service discounts and leverage a common management and support structure to reduce operating costs.

Renewable Energy Systems: Collecting wind data over the air
Renewable Energy Systems (RES) is one of the largest and most successful wind energy companies in the world, involved in nearly every aspect of wind energy projects including research, development, engineering, construction, operation and maintenance. To date, RES has built over 1,100 megawatts of wind plant energy capacity across the United States comprising over 800 wind turbines.

Each of RES’s wind farm projects begins with a research phase in which data is collected at potential wind farm sites to assess their suitability for wind production. This involves erecting 200-foot meteorological towers on the proposed site, often situated in remote locations. Before implementing a wireless solution, RES contracted field technicians to visit each site once a month to retrieve the data and send it back to the RES office for analysis – a time-consuming, expensive process that could be further complicated by equipment malfunctions that stayed undetected for weeks between visits.

With the help of Mobile Electron, one of AirLink’s value added resellers, RES integrated AirLink Raven modems for remote monitoring of wind farm sites. Mobile Electron provided turnkey integration and installation, as well as RF propagation analysis to help RES select the most appropriate cellular provider for a given area. As a result of the deployment, RES has increased operational efficiency and lowered overhead costs, and the company estimates that the cost of the new modems was recovered within six months. The company now has persistent, real-time, two-way connectivity between its regional offices and its remote equipment, enabling automated collection and retrieval of critical data. The solution has allowed RES to detect technical issues more quickly, and has eliminated the need for costly site visits. For more details, please see
