Multi-Color LiFi (WDM-VLC)
Wavelength Division Multiplexed Visible Light Communication
Indoor lighting communication transmitting independent data streams over Red, Green, and Blue LED light wavelengths simultaneously.
Technical Explanation
While single-color LiFi delivers several gigabits, Multi-Color LiFi utilizes Wavelength Division Multiplexing (WDM) across separate Red, Green, Blue, and Amber LED or micro-laser wavelengths. Combined, the colors produce warm, natural white room illumination for human eyes while an array of color-filtered avalanche photodiodes decodes independent 25 Gbps data streams from each individual color channel, delivering 100 Gbps wireless speeds under desk lamps.
Key Functions
- Multiplexes independent high-speed data streams over RGB light wavelengths
- Delivers warm white illumination to rooms while streaming >100 Gbps wireless data
- Eliminates radio frequency interference in hospitals, aircraft, and hazardous plants
- Confines wireless data securely inside walls, preventing external eavesdropping
