Context-Aware PHY
Environment-Adaptive Physical Layer Modulation
A physical layer that dynamically alters modulation constellations, waveforms, and pilots based on real-time awareness of user activity, speed, and weather.
Technical Explanation
Classical physical layers apply static modulation tables (QPSK up to 4096-QAM) determined solely by signal-to-noise ratio. Context-Aware PHY incorporates contextual intelligence: it knows whether a user is walking inside an office, driving on a highway, or standing in torrential rain. The physical layer dynamically switches between OTFS (for high speed), Sub-THz SC-FDE (for heavy rain), and learned neural constellations to optimize energy efficiency and throughput.
Key Functions
- Dynamic modulation and waveform switching driven by real-time contextual intelligence
- Adapting physical layer numerology based on user speed, activity, and weather forecasts
- Seamless switching between OFDM, OTFS, and single-carrier waveforms in real time
- Deep integration with device IMU (accelerometer/gyroscope) and GPS sensors
- Maximizing energy efficiency and packet delivery success in volatile environments
