Abstract
Wi-Fi and Li-Fi are two modern era technologies that are used for data communication. Wi-Fi stands for Wireless Fidelity and Li-Fi stands for Light Fidelity. Wi-Fi uses radio frequency (RF) waves to for transmission of data, on the other hand Li-Fi uses light signals or visible light for data communication. Li-Fi provides transmission of data through illumination by sending data through an LED light bulb. Wi-Fi and Li-Fi technology is used in the various applications of daily life. Both the technologies differ in their properties, architecture, and working. Li-Fi is based on the IEEE 802.11ad standard and uses VLC for data communication while Wi-Fi uses the IEEE standard 802.11 on different devices like routers to transmit data. The objective of this research work is to highlight security prospective of these both technologies; various attacks which can occur and their counter measure as well as misconceptions related to both Wi-Fi vs. Li-Fi is presented in this research paper. Wi-Fi is widely implemented in many major and minor fields of life and the capacity it is providing is accessed. Li-fi, on the end hand, is a means of an opportunity to further develop the efficiency and use of data and to provide resources that are required for the future needs.
Highlights
Wi-Fi and Li-Fi are at two types of wireless technologies i.e. data is wirelessly transmitted in these technologies
The components of Wi-Fi include Routers, and it works on Radio Frequency (RF) waves to for communication, where Li-Fi uses LED bulbs and Visible Light Communication (VLC) light signals for communicating wirelessly (Shetty, 2016)
The IEEE 802.11 standard and specifications forms the basis of Wi-Fi technology and IEEE 802.11ad is the standard for Li-Fi
