In an age where connectivity is becoming as crucial as electricity or running water, MediaTek is pushing forward the boundaries of what is possible in communication technology. The company is at the forefront of developing 6G satellite connectivity, which promises to provide open, fast, and pervasive global connectivity. This visionary approach is not just about faster internet speeds but about creating a seamless, integrated communication experience that combines satellite and terrestrial mobile networks into a single device.

A Seamless Integration of Networks

Leveraging Global Open Standard Technology

MediaTek underscores the benefits of leveraging global open standard technology to integrate satellite communication with the existing global mobile cellular ecosystem. By doing so, they aim to transition satellite communication from a niche market to mainstream consumers and businesses, allowing devices to switch effortlessly between satellite (Non-Terrestrial Network, or NTN) and mobile cellular networks. MediaTek’s development of the MT6825, the first commercially available 5G IoT-NTN chipset designed for narrowband satellite communications, is a testament to this vision. The MT6825 chipset is capable of connecting to Geosynchronous Equatorial Orbit (GEO) constellations, which are compatible with 3GPP NTN-compliant networks and are currently operational in orbit.

The MT6825 is not just a technological marvel but a step towards democratizing internet access and enabling innovative digital services. By integrating satellite communication with terrestrial networks, MediaTek aims to create a ubiquitous communication environment that is always connected. This integration will allow for more resilient and reliable networks, especially in remote or underserved areas where terrestrial networks may be sparse. The ability to switch between satellite and mobile cellular networks seamlessly will ensure that users experience uninterrupted connectivity, paving the way for new use cases and applications that were previously unattainable.

Advancements in NR-NTN Technology

MediaTek’s continuing leadership in NTN connectivity is highlighted by its active development of NR-NTN technology, promising wideband connectivity via both GEO and Low Earth Orbit (LEO) satellites. This innovation aims to enhance potential use cases and applications for smartphones and other cellular-based devices operating over the FR1 spectrum. Demonstrating their cutting-edge capabilities, MediaTek showcased the world’s first NR-NTN device prototype equipped with a Ku-band phased array antenna and Ephemeris-based beamforming at MWC 2024. This advancement ensures uninterrupted global data streaming at broadband speeds over the Ku-band, accurately tracking and compensating for the movement of LEO satellites and ground devices.

The introduction of NR-NTN technology marks a significant milestone in the evolution of global connectivity, offering promising solutions for wide-ranging applications from remote sensing to enhanced mobile user experiences. The Ku-band, part of the electromagnetic spectrum in the microwave frequency range (12 to 18 GHz), is widely utilized for satellite communications and partially overlaps with potential 6G spectrum candidates in cellular FR3. This overlap can pose coexistence challenges between 6G and satellite communication systems. Nonetheless, integrating NTN technology into the native 6G specification could provide a seamless satellite and mobile cellular network with coordinated, shared spectrum utilization, unlocking pervasive global connectivity for mobile devices.

Looking Forward to the Future of Connectivity

Challenges and Opportunities

MediaTek argues that proprietary NTN solutions are likely to struggle to integrate satellite and mobile cellular networks within each device, which would ultimately limit their applications and market presence in the 6G era. The company’s approach is different, focusing on the seamless blend of terrestrial and satellite technologies to create a truly global communication system. By adhering to 3GPP standards and utilizing Ku-band connectivity, MediaTek aims to promote a future where a globally applicable cellular modem is not just a possibility but an operational reality. They plan to unveil the next iteration of their NR-NTN technologies at MWC 2025, setting the stage for further advancements in this field.

The potential benefits of integrating satellite and terrestrial networks are vast, and the challenges, though significant, are not insurmountable. As MediaTek continues to innovate and push the boundaries of what’s possible, the future of global connectivity looks brighter. The company’s commitment to developing scalable, reliable, and seamless communication solutions is a critical step toward making the world more connected. By focusing on open standard technologies and broadening the scope of NTN integration, MediaTek is laying the groundwork for a future where connectivity is truly global and inclusive.

MediaTek’s Vision for a Connected World

In today’s world, where staying connected is as essential as having electricity or running water, MediaTek is breaking new ground in communication technology. With a focus on the future, the company is leading the charge in developing 6G satellite connectivity. This advancement is set to offer open, swift, and widespread global connectivity. MediaTek’s forward-thinking strategy isn’t solely about achieving faster internet speeds; it’s about crafting a unified communication experience. By integrating satellite and terrestrial mobile networks into a single device, they aim to create a seamless network that covers every corner of the globe. This approach will revolutionize the way we communicate, ensuring that users can stay connected no matter where they are. The vision encompasses both improving connectivity and making it more accessible and reliable for everyone, truly changing the landscape of global communication. MediaTek’s work is pivotal in driving the next wave of technological evolution, bringing us closer to a truly interconnected world.
