Xiaomi 15 Ultra Globally Launches First-Ever Direct-to-Satellite Data Feature: A Joint Innovation by China Telecom, Xiaomi, and DingTalk

On February 28th, the Xiaomi 15 Ultra flagship phone was officially launched, garnering significant attention for its world-first direct-to-satellite data feature. This innovative technology, a collaborative effort between China Telecom Satellite Corporation, Xiaomi, and DingTalk, marks a significant step forward in mobile satellite communication. Currently supporting only the DingTalk app, the feature allows users to send images and instant messages via the satellite network, providing reliable communication in extreme environments.

This launch is not merely a hardware upgrade; it represents deep technical and application-level cooperation among the three companies. China Telecom Satellite Corporation played a crucial role in R&D, leading the development of the direct-to-satellite data technology for mobile phones. The core challenge was enabling image transmission without altering the phone's hardware design. This required overcoming numerous technical hurdles, including efficiently utilizing limited satellite bandwidth, maintaining image clarity under high compression, and ensuring communication stability in complex satellite network environments.

To address these challenges, China Telecom Satellite Corporation spearheaded the development of AI-enhanced image encoding, decoding, and compression technology. This technology compresses images thousands of times or more, minimizing data usage while preserving crucial informationessential for bandwidth-constrained satellite communication. Even simple text and crucial images can be transmitted quickly and efficiently under limited bandwidth in emergencies.

DingTalk also played a vital role. Its AI algorithms further compressed images, maintaining clarity over the satellite network. Protocol optimizations significantly reduced transmission times, improving user experience. Furthermore, DingTalk developed the app's satellite data mode to ensure stable transmission of images and text in emergencies, maximizing bandwidth utilization and preventing congestion or delays.

Xiaomi provided strong support in both hardware and software. The Xiaomi 15 Ultra supports Beidou satellite communication across the entire product line, allowing users to make real-time voice calls and send/receive two-way text messages even without terrestrial network access. This offers a 24/7 communication backup solution, crucial in emergencies to maintain contact with the outside world.

Notably, the Xiaomi 15 Ultra offers an optional dual-satellite version, accessing both China Telecom's Beidou and China Mobile's Beidou satellite communication services. This expands satellite network coverage, further enhancing reliability and stability. This dual-satellite option showcases Xiaomi's continued investment in satellite communication and its commitment to user experience.

The realization of the direct-to-satellite data feature is a testament to the collaborative efforts of the three companies and exemplifies technological innovation. China Telecom Satellite Corporation provided core technical support, Xiaomi provided the hardware platform and software adaptation, and DingTalk optimized the application layer. Each company leveraged its strengths, resulting in a breakthrough in direct-to-satellite data for mobile phones.

This technology not only provides a reliable means of staying connected in extreme environments but also points the way forward for mobile satellite communication. It proves the feasibility and practicality of direct-to-satellite data technology, opening possibilities for more applications. We can expect more apps to support this technology in the future, expanding its reach and benefiting a wider user base.

As the technology matures, direct-to-satellite data capabilities will likely become a standard feature in mobile phones, providing more secure and reliable communication. Its widespread adoption will drive rapid growth in the satellite communication industry, bringing greater convenience and security to people's lives.

While currently limited to the DingTalk app, future development and expanding application scenarios will likely see more apps joining this ecosystem, enriching the satellite communication experience. This will further expand the boundaries of satellite communication applications, better serving people's lives and work.

The Xiaomi 15 Ultra's launch demonstrates significant progress in China's satellite communication technology. This mature application not only enhances China's global competitiveness in satellite communication but also provides a model for other countries and regions. We anticipate broader application of this technology in the near future, bringing more convenient and reliable communication services to users worldwide.

In conclusion, the Xiaomi 15 Ultra's world-first direct-to-satellite data feature exemplifies technological innovation and industrial collaboration, marking a new milestone for mobile satellite communication technology. Its successful application solves communication challenges in extreme environments and presents new possibilities for the future of satellite communication. We look forward to its wider adoption, bringing convenience and security to more users.
