LiFi

Li-Fi, also known as Light Fidelity, is a wireless communication technology that uses light to transmit data. It works by modulating the intensity of visible light to encode information, which is then transmitted to a photo-detector that converts the light back into an electrical signal.
Li-Fi is an alternative to traditional radio-based Wi-Fi and has several advantages, including faster data speeds, improved security, and a greater ability to transmit data through solid objects. Unlike Wi-Fi, which uses radio waves, Li-Fi uses light, making it less prone to interference and easier to control.
Li-Fi is still in its early stages of development, but it has potential applications in a wide range of industries, including healthcare, education, transportation, and entertainment. For example, Li-Fi could be used to provide high-speed Internet access in environments where radio-based Wi-Fi is not feasible, such as in aircraft cabins or in hospital operating rooms.
Overall, Li-Fi is an exciting new technology that has the potential to transform the way we communicate and access information wirelessly.

Why did LiFi fail?

Li-Fi has not necessarily failed, but it has not yet achieved widespread adoption and commercial success. There are several reasons for this, including:

• Technical challenges: Li-Fi requires a line-of-sight between the light source and the photo-detector, which can limit its range and flexibility. Additionally, the technology is still in its early stages of development and has not yet been fully optimized for commercial use.
• Cost: Li-Fi technology can be more expensive to implement compared to traditional Wi-Fi, which may limit its adoption.
• Competition: Wi-Fi is a well-established technology that has a large and growing infrastructure, making it difficult for Li-Fi to compete and gain market share.
• Awareness: Li-Fi is still a relatively unknown technology and many people are not familiar with its potential benefits.

Despite these challenges, there is still significant interest and investment in Li-Fi technology, and it has the potential to revolutionize the way we access and transmit information wirelessly. The technology is evolving rapidly and as it improves, it may become a more viable alternative to traditional Wi-Fi in certain applications and environments.

Difference between LiFi And WiFi

Feature	Li-Fi	Wi-Fi
Technology	Uses light to transmit data	Uses radio waves to transmit data
Bandwidth	Can provide high bandwidth and data speeds	Limited bandwidth and data speeds
Security	More secure due to limited range and line-of-sight requirement	Less secure as radio waves can penetrate walls and other obstacles
Interference	Less prone to interference as light cannot penetrate solid objects	Prone to interference from other devices using the same frequency
Range	Limited range due to line-of-sight requirement	Longer range as radio waves can penetrate walls and other obstacles
Cost	Can be more expensive to implement	Lower cost and more widely available
