3. WHAT IS EDGE
EDGE is transmission of data through illumination
,sending data through a LED light bulb that varies in
intensity faster than human eye can follow

4.  The technology truly began
during the 1990's in
countries like Germany,
Korea, and Japan where
they discovered LED's
could be retrofitted to send
information. Harald Haas
continues to wow the world
with the potential to use
light for communication

8.  Radio Spectrum is congested but the demand
for wireless data double each year .Every
thing, it seems want to use wireless data but
the capacity is drying up.
 So what can carry this excess demand in the
future .

10. Li Fi technology is still in its infancy .However
some areas where it seems perfectly applicable
are:-
TRAFFIC LIGHTS
 Traffic lights can communicate to the car and with each
other.
Cars having LED-based headlights, LED-based back lights,
cars can communicate with each other and prevent accidents
by exchanging information.

11. Visible Light is more safe than RF, hence it can be used in
places where RF can't be used such as petrochemical plants
, airplanes etc.
 There are millions of street lamps deployed around the
world.
Each of these street lamps could be a free access point.

12.  ON OCEAN BEDS
Li-Fi can even work underwater were Wi-Fi fails completely,
thereby throwing open endless opportunities for
military/navigation operations.

13. It is possible to achieve more than 10Gbps,
theoretically allowing a high definition film
to be downloaded in 30 sec.
 Mostly powered by LEDs, so it is cost efficient.
 Transmission of data is fast and easy.
 It’s main advantage is it’s bandwidth.
It is 10,000 times than the radio waves

14. Presence of light is essential.
There should be line of sight.
Works better with fluorescent light
and LEDs but very low efficiency with bulbs

15. POTENTIAL APPLICATION OF
LI-FI
INTRINSICALLY SAFE
ENCIRVOisiNblMe LEigNhTt Sis more safe than RF, hence it can be used in
places where RF can't be used such as petrochemical plants
, airplanes etc.
 PUBLIC INTERNET HOTSPOTS
There are millions of street lamps
deployed around the world.
Each of these street lamps could be a free
access point

16. POTENTIAL APPLICATION OF
LI-FI
Li Fi technology is still in its infancy .However some
areas where it seems perfectly applicable are:-
TRAFFIC LIGHTS
 Traffic lights can communicate to the car and with each
other.
Cars have LED-based headlights, LED-based cack lights,
and cars can communicate with each other and prevent
accidents in by exchanging information.

17. POTENTIAL APPLICATION OF
LI-FI
 ON OCEAN BEDS
Edge can even wok underwater were Wi-Fi fails completely,
thereby throwing open endless opportunities for
military/navigation operations.

18. The possibilities are numerous and
can be explored further. If this
technology can be put into practical
use , every bulb can be used
something like a Wi-Fi hotspots to
transmit wireless data.
