Visible light communication (VLC) is an upcoming wireless technology for next-generation communication for high-speed data transmission. It has the potential for capacity enhancement due to its characteristic large bandwidth. Concerning signal processing and suitable transceiver design for the VLC application, an amplification-based optical transceiver is proposed in this article. The transmitter consists of a driver and laser diode as the light source, while the receiver contains a photodiode and signal amplifying circuit. The design model is proposed for its simplicity in replacing the trans-impedance and transconductance circuits of the conventional modules by a simple amplification circuit and interface converter. The system was tested at communication distances of 1m and 3.5m using a terminal emulation program for data transfer between two computing devices.

The main focus of this paper is to clarify the concept and working of Li-Fi technology. In present era, wireless communication plays an important role in day to day life. Wifi is the most used wireless technology which transmits data through radio frequencies. However, during multiple accesses WiFi is facing many challenges related to speed, security and efficiency. Also, WiFI emits radio waves which are harmful in hospitals for patients and cannot be used in underground communication and airplanes. These limitations of WiFi are overcome by Li-Fi technology. The term Li-Fi stands for Light Fidelity which uses visible light communication (VLC) to transfer data at high speed. In this paper, a detailed study on Li-Fi technology, its working and future scope is discussed.

Light fidelity is a upcoming technology for high speed data transmission and controlling home appliances. Visible light communication is the technology used in Li-Fi that uses Light emitting diodes. The evolution of Li-fi is to overcome the rate of speed and security in Wi-Fi. The photo diode in this will convert the flashes into electrical signal and it is amplified to provide output. The optical carrier for data transmission is between 400 THZ and 800THZ.The main advantage of Li-Fi is high density, high speed and high accuracy.
