Sub-THz Beam Tracking
Ultra-Fast Predictive Beam Tracking
AI-driven algorithms that maintain razor-sharp Sub-THz pencil beams during rapid user movement and instantaneous human body blockages.
Technical Explanation
Because Sub-THz signals travel in razor-sharp pencil beams (less than 1-2 degrees wide), even slight user movement, device tilting, or walking pedestrians can break the line-of-sight link, causing connection drops. Sub-THz Beam Tracking utilizes extended Kalman filters, deep reinforcement learning, and spatial trajectory forecasting to predict blockages milliseconds before they occur, pre-steering alternate beams via Reconfigurable Intelligent Surfaces (RIS) without dropped packets.
Key Functions
- Millisecond-level predictive beam steering for razor-sharp Sub-THz pencil beams
- Predicting physical blockages using integrated radar and movement telemetry
- Autonomous seamless handover to alternate reflected paths via intelligent surfaces
- Elimination of repetitive, high-overhead beam sweeping procedures
- Maintaining persistent multi-gigabit connections for moving users and vehicles
