WiFi has become an essential part of our lives, however, internet connectivity issues are still prevalent worldwide. LiFi, a lesser-known light-based WiFi that employs light instead of radio waves to transmit information, has several advantages and is currently being developed by many organizations around the world.
The concept of LiFi was first introduced by Professor Harald Haas in 2011. The term LiFi is short for "Light Fidelity", is a technology that enables communication through light. It uses light to transmit data, being able to connect to high-speed internet just by flicking a light switch, is an extraordinary advance over today's wireless networks.
LiFi works by capturing data in modulated light frequencies of a solid-state LED light source, which is then transmitted and received by LiFi-enabled devices. The light pulses, which are completely imperceptible to the naked eye, are captured and converted into a binary system. Then, like any other digital information, it's translated by our connected devices.
· High-Speed Data Transmission: With the ability to modulate light signals at very high frequencies, LiFi can achieve data rates in the gigabits per second (Gbps) range.
· Greater Bandwidth: The visible light spectrum used by LiFi offers a vast amount of available bandwidth for data transmission.
· Immunity to Electromagnetic Interference: LiFi can provide more reliable and interference-free communication in environments where electromagnetic interference is a concern, such as hospitals, industrial settings, and aircraft cabins.
· Enhanced Security: Since light signals do not easily penetrate walls, the coverage area of a LiFi network is limited to the physical boundaries of a room or space.
· Availability in Restricted Radio-Frequency Environments: LiFi operates on a different part of the electromagnetic spectrum and does not interfere with existing RF-based systems.
· Energy Efficiency: LiFi technology can leverage existing LED lighting infrastructure to provide wireless communication capabilities without significant additional power consumption.
Overall, LiFi technology has the potential to complement existing wireless communication technologies. With the potential to revolutionize the way we interact with technology, LiFi technology is a promising innovation that could change the way we connect to the internet, it is believed that the two-way cooperation with Wi-Fi will make the implementation of wireless data transmission more perfect and efficient, leading a new smart life.
