California-based Semtech has integrated non-terrestrial network (NTN) support into its HL7810 and HL7812 LPWA modules to enable uninterrupted global connectivity.

The modules, now upgraded with NTN support via a software update, let devices maintain global connectivity through satellite networks, supporting continuous connection even in isolated regions.

The modules were part of the Sierra Wireless portfolio that Semtech acquired last year.

Semtech has partnered with Skylo, a pioneer in offering satellite over cellular services, to integrate NTN capabilities into its HL modules. As a result of this collaboration, Semtech’s upcoming software update, slated for commercial release this quarter and pending testing and certification, will provide access to Skylo’s network.

Providing the option to connect using NB-IoT over a satellite network when traditional terrestrial coverage fails not only enhances the reliability of global communication but also reduces waste and loss. This can be crucial for sectors such as shipping and emergency management. The ability to maintain continuous coverage, particularly in applications such as container tracking, addresses the problems posed by the limitations of conventional cellular networks, marking an advancement in enabling consistent connectivity.

“By incorporating NTN support into our HL78 modules via a straightforward software update, we are enhancing the capabilities of our existing products, providing our customers with a substantial competitive edge,” said Michael Buonassisi, director at Semtech. “This initiative demonstrates our dedication to innovation and our proactive approach to addressing the market’s evolving needs.”

Andrew Nuttal, CTO of Skylo (, added: “We are thrilled to partner with Semtech to bring the power of NTN to the HL series modules. This collaboration marks a significant milestone in our mission to bridge the connectivity gap, providing reliable, global communications that meet the needs of today’s digital world. Together with Semtech, we are setting a new standard for connectivity, ensuring that no device is left unconnected, no matter where it is located on the globe.”

In addition to supporting satellite, the HL78 modules ( ( can also support terrestrial LPWA networks using Cat-M and NB-IoT. By pairing with AirVantage smart connectivity, users can take advantage of one global SIM as well as a single point of access to device and SIM lifecycle management.

“As the communication industry evolves towards more integrated and versatile options, Semtech continues to lead the way, driving innovation and delivering technologies that connect the world,” said Nicolas Damour, senior director at Semtech (
