Starting with a short review on High Brightness (HB) LEDs and their recent performances reaching up to 100 Lm W-1, the researchers examine the processes and techniques of using light emitted by LEDs as a medium for carrying data. The technology exploits the inherent high rate switching characteristic of these devices. In addition, investigation on different modulation techniques is explained. Recent developments in VLC and its potential application areas are discussed. A prognosis for future trend, functional requirements and challenges are also discussed. ER -
