1. 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=4 m40s

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

10. Any Questions?
