Application of Li-Fi Technology in Wireless Communication Systems

Abstract

Light Fidelity is referred to as Li-Fi. The German physicist Harald Haas first presented the concept in 2011 at the Visible Light Communication TED (Technology, Entertainment, Design) Global Talk (VLC). Light-emitting diodes (LEDs) are used in the wireless optical networking technology known as Li-Fi to transmit data. The term "Li-Fi" refers to visible light communication (VLC) technology that complies with the IEEE standard IEEE 802.15.7 and employs light as a medium to deliver high-speed communication like Wi-Fi. Similar to Wi-IEEE Fi's 802.11 standards, the IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology standard. Leaks of liquefied petroleum gas can occur within a building, a house, a car that runs on gas, or a vehicle that transports gas. This gas can be deadly if it leaks since it increases the possibility of a building catching fire or exploding, which would be a catastrophe. The causality brought on by this risk is still frequently covered in the media. When gas is detected, the designed system sounds an alarm and uses a GPS receiver to pinpoint the position. Both a valve and a wireless communication module, or LiFi, can be used to control gas leaks. Leaking gas is continuously monitored in real-time.
