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.
