Now-a-days, internet is the basic requirement of many people to fulfill their task through wired or wireless network. As no of user increases in wireless network, their requirement increases that leads to decreases in speed proportionally. Although Wi-Fi has a speed of up to 150mbps as per IEEE 802.11n, it is still in shortage for accommodating huge requirements of users. To rectify this limitation of Wi-Fi, the author introducing the concept of Li-Fi.
