Contact Less High Speed Data Transfer using Light

Abstract

The project we are going to take-up is "Contact Less High Speed Data Transfer using Light". The purpose of this device is to provide an air gap between systems in different security classifications while transferring data between them. This enables data sharing without worrying about the network/bluetooth/wireless protocols that have been found to be vulnerable. These devices can be used in line of sight areas. The challenges would be to provide data throughputs of the rate of Mbps as these LEDs or Lasers work only at Kbps speeds and also to preserve the integrity of the data transferred. Light is omni present and hence prevention of interference from other light emitting devices would be another challenge. Though LiFi has been talked about almost about 5 years back, there is no robust system in place to provide such systems in a practical environment.
