- Li-Fi, a LED-based broadband technology will soon replace WiFi
- An engineering professor developed the technology in 2011
- He said Li-Fi transmit larger data at a much greater speed
- The technology will be out in the market within 2 to 3 years
An Edinburgh professor is on the verge
of another breakthrough in communications technology that will soon
replace the WiFi (wireless fidelity) as the main access to the internet
in home, offices and public places.
Li-Fi explained
Li-Fi is a bi-directional, high-speed
and optical networking technology which uses off-the-shelf LED bulb with
incorporated chips to transmit data, just as WiFi does.
The chip is mainly used to rapidly
modulate the intensity of light in order to encode binary data as ones
and zeros. The light is from these bulbs is then receive by the device
photoreceptors.
The LED can send large amount of data which simply looks like a white light to the human eye.
