Unified 6G Air Interface
Single Harmonized Waveform and Frame Structure for Macro, Sub-THz, and Satellite
Holistic radio protocol framework spanning from sub-1 GHz rural coverage to 300 GHz terahertz indoor links and satellite constellations.
Technical Explanation
In 4G and 5G, disparate standards, numerologies, and proprietary waveforms arose across cellular, satellite, and short-range Wi-Fi. The Unified 6G Air Interface provides a single parameterized, software-reconfigurable frame structure and waveform that dynamically scales across sub-1 GHz macro-cells, 7-24 GHz upper mid-band, 100-300 GHz sub-THz, and LEO satellite Doppler regimes with shared hardware basebands.
Key Functions
- Harmonizes cellular, satellite, and sub-THz communications under one protocol stack
- Scales sub-carrier spacing and slot timing seamlessly across 500 MHz to 300 GHz
- Drastically reduces silicon complexity and cost for global multi-standard modems
- Eliminates disparate legacy protocol conversion gateways and latency buffers
