1.Life with Li-Fi
The dramatic growth
in the usage of LEDs for lighting provides the opportunity to incorporate Li-Fi
technology into a plethora of LED environments, for instance any lighting
devices like car lights, ceiling lights and street lamps are used as a hotspot
which helps us to lower cost architecture for a hotspot.
This
technology is particularly suitable for many popular internet applications; you
can download movies, games and music in just a few minutes with the help of
Li-Fi.
Due to its advantages, Li-Fi has a lot of Life applications. Here we will talk about some important applications of it.
a.Underwater
Communications
b.Traffic Management
Li-Fi can help in
managing the traffic in a better manner and the accident numbers can be
decreased. Traffic lights can communicate to the car and with each other to
manage the traffic in the street.
Traffic light can play the role of the
sender of the data to provide information to the car on the status of the road
or about the situation of other cars.Also cars can communicate with each other and prevent accidents by exchanging information.
For example, LED car lights can alert drivers when other vehicles are too
close.
c.
Airways
We
have to switch off mobiles in aircrafts to prevent overlapping of mobile phone
signals with navigation and control signals used by aircraft. Li-Fi can be
safely used on planes because it doesn't interfere with RF(Radio Frequency). Since it Data is
present where light is present, we can use the lights above the seats in the
plane as hotspot.
d.
Medical Applications
One
of the most important features of Li-Fi is that it could be used in hospitals
and medical settings that require the lack of RF(Radio Frequency) signals which affect the
medical equipment. For example, OTs (Operation theatres) do not allow using
Wi-Fi due to radiation concerns because usage of Wi-Fi blocks the signals for
monitoring equipments. So, it may be dangerous to the patient's health.
e.Blind
Indoor Navigation System
Indoor navigation is convenient for
everyone, and it is especially indispensable for the visually impaired.LED lights emit visible light with location data and an embedded system or
smartphone with a visible light receiver which receives the data. The embedded
system or smartphone calculates the optimal path to a designation and speaks to
the visually impaired through a headphone.
f.In
Sensitive Areas or in Hazardous Environments
Li-Fi provides a safe
communication in environments such as mines and petrochemical plants, because
it doesn't cause electromagnetic interference which appears in RF(Radio Frequency) communications.Li-Fi can also be used in petroleum or chemical plants where
other frequencies could be hazardous.For example,power
plants like nuclear power plants require grid integrity and monitoring of the
station temperature that need fast, inter-connected data systems. Wi-Fi and
many other radiation types are bad for sensitive areas surrounding the power
plants. Li-Fi could offer safe,abundant connectivity for all areas of these
sensitive locations.
Moreover this technology
also enables us to control plants and their growth without direct presence.
g.Disaster
Management
Li-Fi
can be used as a powerful means of communication at times of disaster such as
earthquake or hurricanes, for example places like subway stations and tunnels
which are common dead zones for most emergency communications, don't pose
obstruction for Li-Fi, so it can be used there, as emergency communication.NEXT COMING:::SYSTEMS OF LI-FI
