Sierra Wireless Announces LTE Cat-1 Design Win with Maestro for Fleet and Asset Tracking Worldwide

AirPrime® HL Series provides Maestro with LTE Cat-1 cellular connectivity for track-and-trace devices that are deployed in harsh mobile environments

VANCOUVER, British Columbia--(BUSINESS WIRE)--December 9, 2015--Sierra Wireless (NASDAQ: SWIR) (TSX: SW) today announced that Maestro Wireless Solutions Limited, a leading provider of tracking devices for IoT applications globally, has announced its first LTE Cat-1 tracker based on the AirPrime HL Series from Sierra Wireless. Maestro’s newest tracker, the ruggedized MT-44, provides fleet and asset tracking capabilities in harsh mobile environments using the LTE Cat-1 module with maximum data rates of 10 Mbps downlink and 5 Mbps uplink.

“We have been integrating Sierra Wireless modules into our products for more than 15 years and we have always trusted the company to deliver on leading edge cellular technologies that improve product performance,” said Xavier Dupont, Chief Executive Officer of Maestro. “The HL Series provides us with a single footprint for 2G and 3G global coverage and the LTE Cat-1 module is utilizing the same compact design in our newest tracker.”

“Today, we are seeing strong interest in our LTE Cat-1 embedded modules optimized for lower bandwidth and power requirements,” said Dan Schieler, Senior Vice President, OEM Solutions for Sierra Wireless. “We are pleased to have Maestro deploying our latest LTE technology in their tracking devices. The HL Series Cat-1 module provides the next step in the evolution for our customers, as service providers are continuing to transition their networks to LTE technology.”

The HL Series uses the CF3™ form factor from Sierra Wireless that is footprint-compatible across product lines and network technologies, and is fully interchangeable with future versions of the modules including LTE-M variants when they become available.

LTE-M is a Low-Power Wide Area (LPWA) technology that will provide a highly efficient cellular option with lower radio-frequency complexity, significantly reduced power consumption (up to 10 years of service on a single AA battery), better in-building signal penetration, and lower costs. Sierra Wireless is an active contributor to the LTE-M standard definition process within the 3GPP and has committed to launching compatible modules timed with network deployments, expected to begin in 2017.

The LTE Cat-1 modules from Sierra Wireless will be commercially available in January 2016 on the HL Series.
