Text Data Transfer Using Li-Fi Communication

Abstract

A new and innovative technology called Light Fidelity (Li-Fi) has been developed in the past few years which are an alternate solution for wireless fidelity (Wi-Fi). Li-Fi uses light source as a transmitting medium for data transmission. The data is transmitted by flickering the light source (i.e. switching them On and Off) at a speed that cannot be noticeable to the eye. In this proposed article, wireless data transfer b e t w e e n t w o systems is established with the support of Li-Fi technology. Here data is transmitted from Tx PC via the LASER module that is driven by the Arduino UNO. On the receiver side data will be received on Rx PC using the photodiode (Solar panel), which is also connected to the Arduino UNO to extract the original data from the light. Li-Fi provides better bandwidth, efficiency, connectivity and security than WiFi and achieved high speeds larger than 1 Gbps under the laboratory conditions. The experimental report shows that the bit rate is enhanced using the proposed system and reached up to 147 bps with 1 0 0 % accuracy, over a 50 cm di sta nc e . And the setup also made it simpler than others out there and overall cost also reduce
