Sierra Wireless AirPrime® Modules Certified On T-Mobile’s NB-IoT Network

Sierra Wireless embedded modules on T-Mobile network will transform IoT applications by enabling lower cost, longer battery life and superior coverage

VANCOUVER, British Columbia--(BUSINESS WIRE)--January 9, 2018--Sierra Wireless (NASDAQ: SWIR) (TSX: SW), the leading provider of fully integrated device-to-cloud solutions for the Internet of Things (IoT), today announced that Sierra Wireless AirPrime® WP77 embedded wireless modules are now certified to operate on T-Mobile’s NB-IoT network, which is live in Las Vegas and will be nationwide mid-year.

NB-IoT, part of the 3GPP standard for Low Power Wide Area (LPWA) networks, supports large-scale IoT deployments such as smart city services, smart metering, supply chain management, and industrial equipment monitoring. LPWA has been embraced by leading global carriers, which helps build a broad base of ecosystem partners, devices and applications for global markets.

Advantages of LPWA compared to traditional cellular connectivity options include:

• Longer battery life targeting up to 10 years.
• Better coverage for IoT devices underground and deep inside buildings.
• Reduced module and deployment cost.

“T-Mobile’s NB-IoT network in the U.S. makes cellular the superior option for connecting IoT solutions, which will benefit existing applications and enable many new ones,” said Dan Schieler, Senior Vice President and General Manager, OEM Solutions at Sierra Wireless. “Sierra Wireless WP77 modules will help customers take advantage of NB-IoT’s improved coverage and battery life, with dramatically simplified development for applications like secure gateways for smart homes and cities.”

The WP77 also supports LTE-M (Cat-M1) with 2G fallback, an integrated GNSS receiver, and comprehensive set of interfaces for connecting sensors with a dedicated application CPU core running the Linux-based open source Legato® application framework. WP77 modules are fully compliant with the 3GPP Release 13 standard and footprint compatible with all 3G and 4G (Cat-1/3/4) WP Series. For more information, visit http://www.sierrawireless.com/LPWA.
