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 reduced.
