What if we could use existing technologies to provide Internet access to the more than 4 billion people living in places where the infrastructure can’t support it? Using off-the-shelf LEDs and solar cells, Harald Haas and his team have pioneered a new technology that transmits data using light, and it may just be the key to bridging the digital divide. Take a look at what the future of the Internet could look like.
Time has changed and may changes have happened in the 21st century.
We have seen the rise of artificial intelligence,virtual reality
Augmented reality and much more.
One such technology that is so promising
that it can revolutionize the way we transfer data is LI-FI
LI-FI or light fidelity is a high speed and fully networked
wireless communication technology,similar to WI-FI
It uses visible light rays to transfer data
and is 100 times faster than WI-FI
This is because light has the capacity to transfer
vastly more amount of data in a less time compared to
Lets make it simple! How does Li-FI work?
The ceiling LED fixture encodes data from the internet
and decodes it into light.
The LED light is switched ON and OFF at a very high rate
too quick to be noticed by the human eye
This process works like a binary code
This light is then recieved by a photon detector which
converts the variation in the intensity of light into
These electrical charges are then converted to binary
data and send to computer or mobile devices
The LI-FI technology was founded by
Let’s see a live demonstration by Herald Hass on LI-FI
Pretty interesting right?
You might still be wondering
Should light be ON all the time?
Herald says “YES”
But light can be dimmed to a state where it is not visible
to the human eye,but can be detected by the reciever
As of now LI-FI technology seems to be very promising
In fact researchers at Oxford have achieved speeds of
224 gigabits per second
which is over 200 times faster than a google fiber
