Rohde & Schwarz and Skylo Technologies Achieve Key Milestone in NB-NTN Device Certification

Rohde & Schwarz, in collaboration with Skylo Technologies, has successfully validated all test cases outlined in Skylo’s network operator acceptance criteria, including newly added scenarios for SMS over NB-NTN (Narrowband Non-Terrestrial Networks). This achievement was made possible using the advanced capabilities of the CMW500 wideband radio communication tester. The accomplishment represents a significant advancement in device certification, positioning the NB-NTN technology for broader adoption.

Skylo Technologies, a global provider of non-terrestrial network (NTN) services, utilizes satellite-based communication to enable smartphone and IoT devices to connect directly via partner satellite constellations. By leveraging satellite spectrum, Skylo ensures continuous connectivity, especially in remote or underserved regions where conventional networks are unavailable. Their certification process is designed to rigorously test and evaluate devices, ensuring they meet high standards of performance and reliability.

The successful testing of SMS over NB-NTN marks an important step toward integrating satellite communication into everyday consumer devices. This breakthrough will allow smartphones, wearables, and other connected devices to maintain messaging capabilities even in areas without terrestrial network coverage, enhancing user safety and communication regardless of location.
