INTRODUCTION

In the last couple of decades technology has made its way into our everyday lives including our homes, our offices and the vehicles we use for travelling. Almost everything is connected nowadays and needs to communicate. As almost every device needs to communicate with each other therefore with the current available technologies the Spectrum is getting scared. Hence there is a need of more Spectrum and due to the population of such Wi-Fi signals it is also getting hazardous for health as Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload. And the requirement of more speed is also getting more wanted these days.

Visible light Communication was first presented by Harald Hass in the year 2011 to TED. It actually uses normal Visible light spectrum as its transmission medium, Normal LED light as its transmitter and Solar panel as its receiver.

Such a System is not yet available with the open Source and real time system design and availability of its spectral length is to ensure the smooth transmission of the dynamically changing data with health-friendly Transmission signals. The making of this system is to demonstrate how real time dynamic data can be sent over li-fi and received over the other end using the solar panel.

This paper provides an explanation of the newly developed technology that is Li-Fi. The paper will discuss the architecture, modulation, performance, and the challenges. The structure of this paper is as follows: in the remaining part of this section we will discuss the Li-Fi concept based on VLC. In section 3 we discuss the architecture of Li-Fi. In section 4 we further analyze the performance of Li-Fi based on the rate, speed and security compared with the Wi-Fi. In section 5 we discuss the challenge in Li-Fi technology, it includes a future research based on the security issue. All the results of this paper are summarized in section 6. The result of this paper can be used as a reference and knowledge when developing a Li-Fi technology.

Applications

With the short wave radiation as used by Li-Fi, the communications cannot penetrate through walls and doors. This makes it more secure and makes it easier to control access to a network. As long as transparent materials like windows are covered, access to a Li-Fi channel is limited to devices inside the room.

We can use the li-fi technology in many ways like:

· Home and building automation’s;

· Underwater application.

· Aviation’s.

· Hospitals.

· Vehicles.
