Rohde & Schwarz has successfully achieved full coverage of Skylo’s comprehensive test plan for devices operating in Narrowband-IoT in Non-Terrestrial Networks (NB-NTN). This milestone also enables SMS services over NB-NTN, paving the way for unlimited connectivity on smartphones, wearables, and IoT devices.

Rohde & Schwarz and Skylo Technologies have verified and validated all of the test cases defined in Skylo’s network operator acceptance criteria, including newly added test cases for SMS over NB-NTN, using the advanced CMW500 wideband radio communication tester. This marks a significant milestone in device certification and paves the way for a successful adoption of NB-NTN technology.

Skylo is a global NTN service provider, whose network takes advantage of dedicated satellite spectrum across various partner constellations, allowing smartphone and IoT cellular devices to connect directly over existing satellites. This technology facilitates seamless communication even in remote areas lacking traditional network coverage. Skylo’s certification process involves rigorous testing and evaluation to ensure that devices meet the stringent performance and reliability standards.

The successful validation of SMS over NB-NTN marks a significant step in bringing satellite connectivity to consumer devices. As a consequence, users of smartphones and wearables can rely on messaging services regardless of their location, which will enhance their safety and communication capabilities in areas without terrestrial network access.
