Li-Fi Explained

In this video, you will learn about the Li-Fi Technology, which is the abbreviation of the term Light Fidelity.
So, in this video, we will see how Li-Fi technology works, what are the advantages of this Li-Fi over other wireless communication technologies like Wi-Fi and 4G/LTE, and what are the applications of this Li-Fi.

What is Li-Fi?

Li-Fi is light based bi-directional, fully networked, wireless communication technology, where the light source is used to transmit the data wirelessly.

By turning LED light On and Off very rapidly (Millions time per seconds), we can transmit the data wirelessly.

Advantages of Li-Fi over other Technologies:

1) Speed: Li-Fi has the capability to provide speed up to 100 Gbps (Max .Recorded speed is 224 Gbps !!!)

2) Security: As light can not cross the walls, so data cannot be hacked by outsiders and hence it provides one more layer of security

3) Safety: Unlike radio waves, exposure to light is safer for human beings

4) Congestion free: The bandwidth of light spectrum is 1000 times more than radio spectrum and hence it is congestion free as well as free of electromagnetic interference

Applications of Li-Fi:
Although Li-Fi is futuristic technology, once it will be commercially available there are many applications of this technologies

1) Hospitals
2) Underwater Communication
3) Vehicular communication
4) High-speed internet through street lights
