Li-Fi Technology

Li-Fi Technology Faster Than WiFi

 What is Li-Fi Technology?

Li-Fi is light fidelity. Li-Fi is the transmission of data through illumination by taking the fiber optics by sending data through a LED light bulb. Li-Fi varies in intensity faster than Human Eye can follow. This is the fast and cheap wireless communication system which is an optical version of the Wi-Fi.

Light Bulbs Could Replace Your Wi-Fi Router !!!

Working :

The operational procedure is very simple, if the led is ON, you transmit a digital 1 if it's off you transmit a 0. The LEDs can be switched on and off very quickly, which gives nice opportunities for transmitting data. Hence all that we required is some LED's and a controller that code data into those LED. We have just varied the rate at which the LED's flicker depending upon the data we want to encode. Thus every light source will as a hub for data transmission.

Comparison Between Li-Fi & Wi-Fi :

• To be technical, WiFi uses the radio wave bandwidth of the electromagnetic spectrum whereas Li-Fi uses the visible wave bandwidth of the electromagnetic spectrum to transfer data.
• Wi-Fi is great for general wireless coverage within buildings, and Li-Fi is ideal for high-density wireless data coverage in a confined area for relieving radio interference issues, so the two technologies can be considered complimentary.     
• It is believed that Li-Fi is more powerful than WiFi and can transmit data in the range of Gigabits per second.    

Speed Comparison Between Li-Fi and Wi-Fi

Applications of Li-Fi:

Some of the applications of Li-Fi are given bellow,

• Medical field 
• Airlines
• Military operations 
• Power plants
• Under seawater.

Conclusion:

The concept of Li-Fi is currently attracting a great deal of interest, not least because it may offer a genuine and efficient alternative to radio-based wireless. As a growing number of people and their devices access wireless internet, the airwaves are becoming increasingly clogged, making it more and more difficult to get a reliable, high-speed signal.
