At the 2025 China International Fair for Trade in Services (CIFTIS) Xiongan New Area Digital Trade Innovation and Development Conference held last week, China Mobile Xinsheng unveiled a major achievement: the official release of China's first RISC-V-based satellite + cellular dual-mode narrowband communication IoT-NTN chip CM6650N, marking another key breakthrough in the domestic communication chip sector.
Fully aligned with the 3GPP R17 Non-Terrestrial Network (NTN) 5G standard, the CM6650N chip boasts outstanding core advantages:
- Ultra-high localization rate: Over 90% localization across chip IP, EDA tools, wafer manufacturing, and packaging, leading in independent controllability.
- Extreme low power consumption: Standby current controlled within 1 microampere, significantly extending the battery life of terminal devices.
- Full frequency band coverage: Operating frequency ranging from 700MHz to 2.5GHz, enabling seamless support for dual-mode communication between terrestrial and satellite networks.
- Full satellite mode compatibility: Adaptable to both high-orbit and low-orbit satellites, and supporting two core modes (regenerative payload and transparent transponder), with wide application scenarios.
The CM6650N’s core strengths also lie in its practical implementation capabilities. Through miniaturized design, combined with two-way voice calls and global connectivity, it can drive large-scale application of satellite communication technology in high-value fields such as smart watches, smartphones, and ocean shipping. Additionally, it provides an integrated "SIM card + chip + data package" solution to help customers quickly launch their businesses, and leverages a connectivity management platform to offer value-added services, accelerating product time-to-market.
ICgoodFind: The launch of China Mobile Xinsheng’s dual-mode IoT-NTN chip not only enhances the competitiveness of China’s domestic IoT-NTN sector but also injects new momentum into the large-scale application of satellite communication.
