A survey on Li Fi technology
In the present era, Wi Fi is the most trending domain. As internet users almost double every year, there is an enormous load on radio spectrum that leads to congestion. To get better bandwidth, efficiency and speed, a new technology Li Fi has evolved. Li Fi stands for Light Fidelity. It is a bidirectional and wireless mode of communication using light. It uses the unused visible spectrum and reduces the load on radio spectrum. Li Fi can be simply put to be Wi Fi but instead of radio waves light is used as a medium. Here, data is transmitted using light whose intensity varies faster than human eye to capture. Instead of using modems, Li Fi uses LED bulbs with transceiver. Data transmission in Li Fi is about 100 times faster than Wi Fi. Here, in this paper we explore the need for Li Fi.
