How does LiFi work in simple words?

LiFi comprises of multiple light bulbs that form a wireless network. When an electrical current is applied to a LED light bulb a stream of light (photons) is emitted from the bulb. The signal can then be received by a detector which interprets the changes in light intensity (the signal) as data.

What is LiFi introduction?

Introduction LiFi known as light fidelity was introduced first time by Prof. LiFi is based on Visual Light Communication (VLC) that using light emitting diodes (LEDs) to fully networked wireless system [1]. LiFi enables the electronic device to connect to the internet with no wire.

How does LiFi image work?

So, Li-fi that is based on the visible light spectrum is being designed. It uses a LED and a photodiode or phototransistor to transmit and receive data respectively. Li-fi can be compared with the existing wireless technology i.e. Wi-Fi in terms of speed and security which the former provides better.

What is the difference between LiFi and WIFI?

Wi-Fi(wireless fidelity) and Li-Fi(light fidelity) both are two different technologies which are used to send and receive data wirelessly. In case of Wi-Fi we use Routers and Radio Frequency (RF) waves to transmit data, whereas in Li-Fi we use LED bulbs and Light signals to transmit and receive data.

Is LiFi faster than Wi-Fi?

Scientists around the globe are field testing LiFi in office and industrial settings, frequently documenting data transmission rates at 1GB per second – that’s 100 times faster than current average WiFi speeds!

Will LiFi replace Wi-Fi?

LiFi, the use of light waves to generate a wireless internet connection, could become the main source of connectivity in buildings within the next 10 years, according to Wiredscore. Essentially it will be a game-changer, using LED lights to generate WiFi. …

Who invented LiFi technology?

Professor Harald Haas
Professor Harald Haas and LiFi Professor Harald Haas and his team of researchers are pioneers in the field of LiFi. They began their research into VLC technology as early as 2006. Much of their research ventured into the use of light as a medium for two-way transmission of data, which paved the way for LiFi technology.

Can LiFi replace WiFi?

LiFi, by contrast, uses an entirely new spectrum—light—to transmit data. Further, LiFi offers significantly higher speeds than WiFi can muster. Another significant advantage of LiFi is that it’s more secure and private than Wi-Fi. Because LiFi signals are line-of-sight only, data doesn’t move through walls.
