Here is a masterpiece. You might have heard about the term Wi
fi and its usage. But have you heard about Li-fi.?? Here is a small intro to that 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.
· 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.
· Its 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.
· 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”

well.. its another new technology created by the humans ..okay..but every new technology has its own disadvantages..is this technology feasible? can it be processed at a lower cost?...when it cannot penetrate walls, it 'll be too difficult to use it everywhere...but it 'll find vast applications in the governmental organisations..hope it'll be productive..
yup.. its feasible da.. it is of great use only in areas where Wifi is ineffective and in densely used areas.. but it will take its time before coming into existence..
a new era in communication.!!.awesome technology by man!!!
will it be suitable in india?
certainly.. but not today. surely by 2030.... ;-)
good piece of information.. US has implemented the fibre-optic communication in few of their government sectors.. However Li-Fi is going to be much more effective than that..
nice tech but juz imagine our environment full of li-fi systems won't there be juz too much light???
too much interference???
Hey dude, it is efficient only in densely populated or highly used areas. So der wont be any interference effect.. Don't think to the extreme.
@ aavee : Rightly said bro. its expected speed is just awesome.
wow wat a technology creatd by human , unbeleivable................
actually it is in the developmental stage, that why it has not got enough popularity. Within 10 years, it will rule the world.
i am waiting for tis....... tanx for ur post my dear handsome guy......
;-) YW...
It will be d best,when it released now.....
its popularity is doubt aftr 20 yrs....
Actually works are going on to release this awesomeness ASAP.. So lets see when will get to use it.
how far is this possible with no electricity in Tamil Nadu...?
This is hypothetical question. It certainly needs electricity buddy. Good question though...!
Li Fi is a great technology indeed. Super invention.!
Li Fi is a great technology indeed. Super invention.!Actually works are going on to release this awesomeness.
Its a great technology alright, but don't u think it has less applications than the technologies usin radio frequencies? Can Li-Fi be used in broad daylight like Wi-Fi? This technology is confined for indoor use only, Can it be used in open environment outdoors like Wi-Fi?
Yeah i do doubt its functionality during bright sky yet there is always room for improvement in the technology and one cant decide its constrain before actually it's out..
very informative post
The "Internet of things" would be very much feasible with this technology...
Nice post
