We
all know about Wi-Fi. The person who has not used Wi-Fi is very rare. Wi-Fi is
widely used in offices, homes and various factories etc. So without Wi-Fi we
can’t even think. But those users, who have become bored by using Wi-Fi, must
be very happy to know about the latest invention of science in the field of
data transmission, that is Li-Fi technology.
Li-Fi has the ability to transfer data 100 times faster than
Wi-Fi technology. Mainly Li-Fi technology is welcomed in the technology market
by Velmenni organization in Estonia .In Tallinn, the capital of Estonia some
industries and offices are using this technology as a trial. The average speed
is 1 GB per second approximate. But in laboratory test the speed can be expanded
up to 228 GB per second. So just think of the lightning speed of that
technology. HD Blu-ray movie can be downloaded within seconds.
Mr. Dipak Solanki, CEO of Velmenni, has enlightened on that
topic and according to him the technology requires 3-4 years more to spread
throughout the world. The Li-Fi was first introduced in 2011, but it is under
testing until last of 2015.
Though the Li-Fi technology is not so popular but we can
understand the working principle of that technology. This technology requires
light. The frequency of the light is very near to the frequency of light which
is visible. The Li-Fi is also known as “Visible light Communication”. In easy
speaking the connection should be made by LED light bulbs. Which means the
connection can be setup where the light is available.
The Li-Fi has some advantages also. Like Wi-Fi we are not
using radio frequency rather we are using light spectrum which is 10,000 times
faster than Wi-Fi transmission frequency spectrum. So from this point the
faster network can be created. But it also have some disadvantages are also.
Wi-Fi radio frequency can penetrate the wall, it can be transmitted through
many different mediums but Li-Fi is not capable of that. As we know the visible
light frequency cannot penetrate the wall, so the in that cases Li-Fi technology
network setup is not possible. We can also compare the both technology
according to the security. We know that Li-Fi can’t be access where visible
light is not available. So from this concept the Li-Fi network is very safe and
secure too. The chance of being hacked is very low indeed.
But after few years we will get the devices in the market to
use this connection. And we will get the facilities too.
