In May 2023, Viasat purchased Inmarsat; the combined company operates over 19 satellites in Ka-, L- and S-bands; we’re most interested in what was the Inmarsat L-band service, as this is the best radio frequency for IoT applications. It’s the network upon which NB-NTN, IoT Nano (OGx), IoT Pro (BGAN M2M) and the Go-anywhere Pro (BGAN) service depends.

New: Viasat NB-NTN
Viasat is in the process of launching a standards-based service utilizing NB-IoT. We anticipate that this service will be available in Q1 2027.
Variously known as standards-based, NTN, and D2D, this new service is based around cellular standards which have been adapted to allow data to travel over satellite using the same protocols. It promises easier integration, lower hardware costs, and for very small volumes of data, lower airtime rates.
It’s important to stress that the NB-NTN service isn’t currently global; coverage is available over North America, Brazil, Australia, New Zealand, and parts of Europe.
RockBLOCK RTU houses the new Viasat NB-NTN SIM; we’re currently testing this, and looking for beta test partners whose application might suit this technology. Please get in touch if it’s of interest.
More About Viasat NB-NTNMore About Viasat
Viasat’s IoT network is in geostationary orbit, some 35,786 km (22,236 miles) above Earth. They have almost global coverage, with only the far north and south latitudes not covered. It is a stable, well established satellite network that’s trusted by Aviation, Government, Infrastructure and Maritime organizations to deliver their data securely.
Viasat’s network is also being leveraged by telecommunication companies like Skylo and Myriota to deliver Non-Terrestrial Network (NTN) NB-IoT services, enabling low-power, wide-area connectivity for IoT devices in remote regions. Viasat is also working on its own NB-IoT service, called IoT Direct. This is expected to unlock new applications for satellite IoT connectivity, as the cost of both hardware and airtime is expected to be lower.
