Li-Fi
So whats li-fi as it is the first article on
the Techwirezz, it’s a great topic to pic as our tag line says “technology
ahead “this is the technology we are accepting in feature. Come to the point
lets Discuss about “Li-Fi”:
Li-Fi is
the name of data transmission technology in which Data is transmitted through
Light or you can say it used illumination technique by taking the fiber out of
fiber optics by sending data through a LED light bulb. “Li” used in name is short form of Light as it uses light as
transmission media. In other words it is the cheap and fast wireless
communication system. It’s the optical version of Wi-Fi.
Li-Fi working in Brief:
Technically
working is very simple, if the led bulb is on, Digital signal in the form of 1 transmitted
and if it’s off its transmits Signal as 0. You can On or Off transmission very
fast because Led can On & Off very quickly. All you required is some LEDS
and controller that code data into those LEDS. You just have to adjust the rate
on which LED’s flickering depends according to data you wants to encode, and
this converts each and every light source into data hub.
