Light Fidelity: A future of wireless communication

Internet speed plays a critical role today in the business and public services arena. High speed internet has taken industry to the new heights specifically in the field of information technology, online education, financial services, entertainment, health care and many more. Currently wireless fidelity (Wi-Fi) is commonly used at homes, organizations, airports and institutions to access the high speed internet. Researchers felt that enhancing the existing speed to the next level will further unlock a plethora of opportunities for the betterment of human life. This technology can be used to enhance the defense technique by replacing it with the radio frequency mechanism and can help to have a secure transmission of data. This paper will help readers to make aware of the new technology being explored called Light Fidelity (Li-Fi). Li-Fi is the next level of technology based on wireless optical communication which uses visible light for data transmission whereas presently Wi-Fi uses radio waves.
