Breaking New Ground in IoT Connectivity: Sierra Wireless HL781x LPWA Module is Successful NTN over NB-IoT Connectivity
In an exciting development for the Internet of Things (IoT) sector, Semtech Corporation (formerly Sierra Wireless) and Rohde & Schwarz successfully demonstrated the integration of Non-Terrestrial Network (NTN) connectivity using the Semtech HL781x Global Low Power Wide Area (LPWA) Module. This achievement marks a significant milestone in transforming Satellite IoT from a buzz concept into a reality ready to revolutionize IoT applications.
Satellite IoT – What is it?
Satellite IoT, particularly Narrowband IoT (NB-IoT) over Non-Terrestrial Networks (NTN), represents a transformative leap in the Internet of Things (IoT) landscape. NB-IoT over NTN leverages satellite communication to provide IoT connectivity in areas where traditional terrestrial networks are unavailable or unreliable. The value of Satellite IoT lies in its ability to ensure continuous and reliable connectivity even in the most remote areas.
This is especially crucial for sectors like logistics and shipping that need real-time data transmission and monitoring across vast and remote geographical areas. It is also key for disaster response, where connectivity is vital for coordinating relief efforts in areas where infrastructure has been compromised. By extending the reach of IoT through satellite technology, NB-IoT over NTN empowers industries to operate more efficiently and make data-driven decisions regardless of geographic constraints.
Satellite IoT - From Concept to Reality
Earlier this year, Semtech announced the integration of NTN support into its HL series LPWA Modules, specifically the HL7810 and HL7812. The collaboration between Semtech and Rohde & Schwarz marks another significant step forward in making Satellite IoT a practical reality.
“This successful demonstration of NTN connectivity on our HL781x modules represents a significant step forward in our mission to provide ubiquitous, reliable connectivity across the globe.”
Michael Buonassisi, Director of LPWA Modules at Semtech
At Semtech's Taiwan facility, engineers utilized the Semtech HL7812 Global LPWA Module in conjunction with the R&S CMW500 wideband radio communication tester from Rohde & Schwarz. Skylo, a pioneer in offering satellite over cellular services, collaborated closely with them providing a live SIM to support the testing in the laboratory and live network.
The HL781x modules are designed to support a variety of LPWA technologies, including LTE-M and NB-IoT, making it a versatile solution for diverse IoT applications. Coupled with the advanced capabilities of the R&S CMW500 platform, which can emulate a wide range of network scenarios for all major cellular technologies from LTE to GSM, the test setup provided comprehensive insights into the behavior of the HL781x modules under realistic conditions, establishing a real-time, comprehensive connection with the simulated satellite network and testing the relevant signaling and RF scenarios in line with the 3GPP Rel. 17 specification.
“Our collaboration with Semtech underscores the importance of rigorous testing and validation in pushing the boundaries of IoT connectivity.” Christoph Pointner, Senior Vice President of Mobile Radio Testers at Rohde & Schwarz.
Semtech’s LPWA HL781x modules can be upgraded with NTN support via a straightforward software update. The upcoming software update, slated for commercial release later this year and pending testing and certification on Skylo’s network, will provide access to Skylo’s expansive network.
This breakthrough has significant implications for the future of IoT connectivity. By enabling devices to maintain connectivity via satellite when terrestrial networks are out of reach, the combination of Semtech’s technology, Skylo’s services and Rohde & Schwarz’s testing platforms opens up new possibilities for global IoT deployments. This achievement paves the way for more resilient and expansive IoT ecosystems, capable of supporting critical applications in even the most remote locations.
