TECHNICAL SEMINAR REPORTON
VISIBLE LIGHT COMMUNICATIONS
Presented byM. Jashwanth
INTRODUCTION
New communication technology using “Visible Light”.
Eliminates most drawbacks of transmission via electromagnetic waves outside the visible spectrum.
TRANSMITTING DEVICES
It uses • fluorescent lamps (ordinary lamps, not special
communications devices) to transmit signals at 10 Kbit/s, or
• LEDs for up to 500 Mbit/s.
General Characteristics
• Eye safety• Security : What You See Is What You Send.• Health : Harmless for human body• Unregulated : no regulation in optical
frequency• Using in the restricted areas : aircraft,
spaceship, hospital
VISIBLE LIGHT COMMUNICATION PROCESS
A SOUND COMMUNICATION SYSTEM
APPLICATIONS
• Defense & Security• Mobile Connectivity• Hospitals & Healthcare• Aviation & Underwater Communications• Vehicle & Transportation• Energy Efficient Communication
CONCLUSION
• VLC is a safe technology• It has the potential to deliver high data transfer
rates.• Light radiation neither constitutes nor suffers
from electromagnetic interference (EMI) making VLC a very attractive technology.
• It can be used where security of local communication is important e.g. defense and other applications.
