Strategic Objectives
• Master the physics of trilateration using existing LED infrastructure.
• Implement high-accuracy fingerprinting techniques for complex environments.
• Understand the geometric precision of Angle-of-Arrival (AoA) estimation.
• Navigate the transition from radio-frequency to optical-based localization.
The Core Challenge
GPS fails the moment you step indoors, leaving a critical gap in our hyper-connected world's ability to locate people and assets precisely.
