Visible light communication


<ul><li> 1. TECHNICAL SEMINAR REPORTONVISIBLE LIGHT COMMUNICATIONSPresented byM. Jashwanth </li> <li> 2. INTRODUCTIONNew communication technology using VisibleLight.Eliminates most drawbacks of transmission viaelectromagnetic waves outside the visiblespectrum. </li> <li> 3. TRANSMITTING DEVICESIt uses fluorescent lamps (ordinary lamps, not specialcommunications devices) to transmit signalsat 10 Kbit/s, or LEDs for up to 500 Mbit/s. </li> <li> 4. General Characteristics Eye safety Security : What You See Is What You Send. Health : Harmless for human body Unregulated : no regulation in opticalfrequency Using in the restricted areas : aircraft,spaceship, hospital </li> <li> 5. VISIBLE LIGHT COMMUNICATIONPROCESS </li> <li> 6. A SOUND COMMUNICATION SYSTEM </li> <li> 7. APPLICATIONS Defense &amp; Security Mobile Connectivity Hospitals &amp; Healthcare Aviation &amp; Underwater Communications Vehicle &amp; Transportation Energy Efficient Communication </li> <li> 8. CONCLUSION VLC is a safe technology It has the potential to deliver high datatransfer rates. Light radiation neither constitutes nor suffersfrom electromagnetic interference (EMI)making VLC a very attractive technology. It can be used where security of localcommunication is important e.g. defense andother applications. </li> </ul>
