Swiss provider u-blox announced its first combined 3GPP-compliant terrestrial network (TN) and non-terrestrial network (NTN) IoT module. The SARA-S528NM10 module supports global coverage with accurate, low-power, and concurrent positioning.
Most satellite systems require proprietary hardware and software, locking users to a specific operator and forcing terminal replacement for switching. The u-blox device, based on global 3GPP standards, offers interoperability with multiple satellite providers, giving customers greater flexibility.
Powered by the UBX-S52 cellular/satellite chipset and M10 GNSS receiver, the module adheres to the 3GPP Release 17 NB-NTN specification. This standards-based approach ensures extended connectivity via LTE-M and NB-IoT on terrestrial cellular networks, as well as NB-IoT on GEO satellite constellations, with readiness for LEO satellites.
The SARA-S528NM10 module supports the two NTN bands introduced in 3GPP Release 17—n255 (L-band global) and n256 (S-band Europe)—as well as the n23 band (US). It is currently being certified by Skylo, a global NTN service provider, for its satellite network. This certification will ensure seamless connectivity with both cellular and Skylo satellite networks.
