Navigation System Using Light Fidelity

These days, the internet usage has been rapidly rising which leads to radio waves being overused. Long distance data transmission makes use of this spectrum. It has become difficult to keep up with the demand for the high speed connectivity as the number of users is increasing. This has led to the shortage of radio wave bandwidth and hence limited speed of data communication. An alternative and advantageous replacement can be visible light communication (VLC). One of the applications of VLC could be road navigation using street lights. Often drivers face issues navigating at night., due to low battery of mobile phone or network connectivity issues. This paper proposes a system to solve the problem of navigation in intra-city roads at night using Li-Fi technology. The street lights would be utilized to transmit images of the map of the area at its immediate vicinity. These would be received by the vehicles for ease of navigation., without the use of mobile data or Wi-Fi, The received image is then displayed on a display screen in the vehicle. This system provides an alternative for the present day means for road navigation.
