In an era of rampant use of wireless connectivity through wireless fidelity (Wi-Fi) all over the world and India along with developing and under developed countries still struggling to reap the maximum benefits of the technology, developed countries are planning to move forward with its new version termed as light fidelity (Li-Fi). This article aims to introduce the working, progress, advantages and limitations of this (Li-Fi) technology in comparison to Wi-Fi technology. Wi-Fi is the name of a popular wireless networking technology that Fig.: Wireless Fidelity (Wi-Fi) to Light Fidelity (Li-Fi) uses radio waves to provide wireless high-speed Internet and network connections. Wi-Fi networks have no physical wired connection between sender…show more content…
Li-Fi signals cannot pass through walls, so in order to enjoy full connectivity; capable LED bulbs will need to be placed throughout the home. Not to mention, Li-Fi requires the light bulb is on at all times to provide connectivity, meaning that the lights will need to be on during the day. Where there is a lack of light bulbs, there is a lack of Li-Fi internet so Li-Fi does take a hit when it comes to public Wi-Fi networks. Experts say that Li-Fi will probably not completely replace Wi-Fi in the coming decades, the two technologies could be used together to achieve more efficient and secure networks. The homes, offices, and industry buildings have already been fitted with infrastructure to provide Wi-Fi, and ripping this entire out to replace it with Li-Fi technology isn’t particularly feasible, so the idea is to retrofit the devices we have right now to work with Li-Fi…show more content…
• Due to this, Li-Fi is reportedly perfect for battery powered devices such as smart watches; smart phones and lends itself to Internet of Things devices such as sensors and smart applications. • Due to its impressive speeds, Li-Fi could make a huge impact on the internet of things too, with data transferred at much higher levels with even more devices able to connect to one another. • Due to its shorter range, Li-Fi is more secure than Wi-Fi and it's reported that embedded light beams reflected off a surface could still achieve 70 megabits per second. • With faster connectivity and data transmission it’s an interesting space for businesses. The integration of internet of things devices and Li-Fi will provide a wealth of opportunities for retailers and other businesses alike. For example, shop owners could transmit data to multiple customers' phones quickly, securely and remotely. • 'Internet of Things', is an optical communication technology that’s taking the world by storm. Light Fidelity or Li-Fi, is an exciting breakthrough in 5G visual light communication systems and the future of wireless Internet
