Li-Fi – new emerging technology
April 2, 2017

Li-Fi Technology

Li-Fi is a high speed Wireless communication technology like Wi-Fi.
Li-Fi is the acronym of Light Fidelity. where light is a type of energy and Fidelity represents the reliability of its nature.
The concept of Li-Fi was brought by a university professor Mr. Hardly Hoses back in 2011, which he shared publically and explained that light technology is also one of the most effective means of data communication. This technology is significantly advance than the Wi-Fi technology.
It is a visible light communication (VLC) running wireless communications travelling at very high speed.
Wi-Fi uses Radio waves to transmit data and Li-fi uses visible light.
The li-fi technology uses light emitting diodes (LED’s) to transmit data.
It is designed to use LED light bulbs. A special chip that modulates the light imperceptibly for optical data transmission.
Li-Fi transmit data using LED bulbs and it receives data by photoreceptors
Li-fi early speed was 150mbps, but after further work the speed now upto 10 Gbps
Light spectrum or bandwidth is approximately 10 thousand times up.
Faster than Wi-Fi
More secure then Wi-Fi, because data cannot be intercepted without clear line of sight
Removes nearby network interference
Low cost
Suitable for electromagnetic sensitive areas like hospitals, aircraft cabins, nuclear plants etc.
Till now Safer for environment plus for human also, no radio waves involved
Short range, requires clear line of sight, cannot penetrate obstacles like concrete walls etc.
Not suitable for mobility
Commercially it is tested and offered in Dubai by two companies du and Zero1. As per them they have successfully provide internet, audio and video streaming.
You can use Li-Fi in plane with low light bulb.
You can use under water with low light torch.
Many toys include LED lights and these can be used to support very low-cost communication between interactive toys.
Laptops, smart phones, tablets and other mobile devices can communicate directly using Li-Fi. Short range links give very high data rates and also provides security.
