advantages and disadvantages of lifi technology

Li-Fi :

Li Fi is nothing but the Light fidelity communication systems.
·It is the fastest and cheapest wireless communication systems and is the optical version of the Wifi. The term was first used by Harald Haas in TED Global talk.
The technology works by adapting LEDs to send digital information, invisible to the naked eye
·A light sensor on a device picks up the digital information sent by the LED, which enables it to be processed by a computer.
It is similar to the Wifi except that it uses Light waves instead of Radio waves.
Advantages
Wifi is great for general wireless coverage while Lifi is ideal for high density coverage in a confined region.
It is believed that the technology can yield a speed more than 10 Gbps, allowing a HD film to be downloaded within 30 seconds.

Disadvantage
is that the light waves cannot penetrate walls.
In 2012, this technology was demonstrated and it was detectable upto a distance of 10 meter.

Amazing Fact about Li-Fi is
· Every light source in homes and offices could potentially be a “Li-Fi” within 20 years.


· When this technology becomes feasible like the Wifi, then our life will be awesome on earth.



"This is the technology that could start to touch every aspect of human life within a decade”
