UNISOC, China's leading chip design company, has collaborated with German electronics testing group Rohde & Schwarz to validate the industry's first 3GPP R17 IoT NTN RF consistency test case. This achievement is based on UNISOC's 5G NTN satellite communication chip V8821.

The successful test confirms that terminals developed using V8821 are suitable for direct satellite connectivity in mobile phones, vehicle-to-vehicle communication, and integrated terrestrial and satellite IoT scenarios. UNISOC sees this validation as a significant milestone, demonstrating the commercial value of their technology. Xian Miao, general manager of UNISOC's Wide-Area IoT Product Division, expressed the company's commitment to further advancing satellite communication-based IoT to enable seamless real-time connectivity. Rohde & Schwarz also emphasized the importance of this partnership and the potential for future cooperation in providing testing solutions for mobile communication and the satellite industry. The integration of ground mobile communication and satellite communication technologies has driven the emergence of NTN technology, which is based on the 3GPP R17 standard and encompasses both Narrowband IoT (NB-IoT) and Broadband NTN. UNISOC's V8821 chip offers high integration, consolidating various communication device functions into a single-chip platform.
