Comparison of Wi-Fi Vs Li-Fi

Abstract

Technology is growing very rapidly and makes things very easy for human life. Due to the innovation of wireless technology in the field of communication, we can connect to every person of the world within a few seconds. Wi-Fi technology is more popular all over the world. Devices which can use Wi-Fi technology include PC, video-game consoles, digital cameras, smart-phones, tablets and digital audio players. But this technology has limited scope. To eliminate the limits of Wi-Fi technology, Li-Fi (Light- Fidelity) technology comes in picture due to their fastest speed of data transfer & high density. Wi-Fi is good for general wireless coverage within buildings, industries, complexes whereas Li-Fi is ideal for high density wireless data coverage in large area and solving radio frequency interference problems. Wi-Fi has already achieved extremely intense speed in lab. Li-Fi provides the better bandwidth, better efficiency & availability and more secure than the Wi-Fi communication. In future Li-Fi technology has used in every sectors.
