  1. Li-Fi (light-fidelity) CST 300L Fall 2013

  2. What is Light Fidelity? • Data communication through Light

  3. How does it work? • LED lights • Orthogonal Frequency Division Multiplexing

  4. Harald Haas explains how it works from: http://youtu.be/NaoSp4NpkGg?t=4m40s

  5. Key Person • Professor Harald Haas, University of Edinburgh

  6. Advantages • Disadvantages • Means for Future

  7. Advantages • Faster Data Speeds • More access to Internet • Use in areas where Data Communication is limited

  8. Disadvantages • Cannot travel from room to room • Detector must face the source of light

  9. Means for Future • Internet on Planes/Anywhere that uses Light • Saves Lives
