Abstract - Nowadays, many people use the Internet to do their work over wired or wireless networks, and wireless network speeds decrease proportionally because neither user is getting an increase. Wi-Fi provides speeds of up to 150 Mbps according to the IEEE 802.1 1n standard, but this is not enough to accommodate users. To solve these limitations of Wireless Fidelity, we present the Li-Fi concept. The data, according to German physicist Harald Haas, uses lights to pluck fibers from the fiber and send the data through an LED bulb whose intensity changes faster than the human eye can track. A communication system that uses light as a carrier instead of traditional radio frequencies as in Wi-Fi. The advantage of Li- Fi is that it does not cause interference and can be used in sensitive areas such as aircraft and other vehicles. However, the light waves used cannot pass through walls. This is typically implemented using the downlink transmitter's white LED bulb
