Integrated device-cloud architecture for the IoT

The WP series is interchangeable and completely footprint-compatible with the AirPrime HL series, and is available in 3G and 4G LTE variants with 2G fallback on certain modules. Like the HL series, the WP series modules can be soldered down or used with a socket, for flexibility in manufacturing and inventory management. The form factor, called CF3, will be supported by Sierra Wireless through multiple generations of both WP and HL series product lines, providing a secure migration path for customers through multi-year deployments.

The next-gen AirPrime WP series offers low power mode for applications that need to prioritise power management over constant connectivity. This deep-sleep mode is suitable for industrial solar- or battery-powered applications where constant connectivity is not required, opening up new use-cases for cellular connectivity where it was previously impractical.

For OEMs and developers, the integration of processors and device software with wireless functionality can be complex and time-consuming, even more so when modifications are required for each region and each generation of the product. If location-based services are required, a GNSS receiver must be integrated as well. Furthermore, the data from the wireless connection, the connected asset, and its location must be aggregated and delivered to enterprise applications.

The next-gen AirPrime WP series is designed to address all of these issues. It offers an integrated processor and a GNSS receiver, reducing the number of components, integration time, and cost for developers. The Linux-based Legato platform running on the module’s processor provides the modem services needed to get the module communicating on a cellular network, plus an application framework and secured processing space to run third-party applications. Through Legato, AirPrime WP modules are pre-integrated with the AirVantage cloud for simple, secure configuration and management of the device and its data once deployed.

“With the introduction of the AirPrime WP series modules, we have launched a powerfully integrated device-to-cloud architecture to make it easier for our customers to innovate,” said Dan Schieler, Senior Vice President, Embedded Solutions, Sierra Wireless. “With an application processor running the open source Legato platform, along with the AirVantage cloud for device and application management, and a new open hardware reference design, the latest WP series modules enable developers to quickly build connected products using a single module to run all their applications.”
