Since it Data is present where light is present, we can use the lights above the seats in the plane as hotspot. [ 12 ] 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 signals which affect the medical equipment. For example, OTs (Operation theatres) do not allow

Blind Indoor Navigation System Indoor navigation is convenient for everyone, and it is especially indispensable for the visually impaired. We proposed such a navigation system for the visually impaired as shown in Figure 10. 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. [ 17 ] Figure 10: Indoor Navigation system for Blind people. 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 interferen ce which appears in RF communications. Li-Fi can also be used in petroleum or chemical plants where other frequencies could be hazardous. [ 15 ] 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. [ 16 ] 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.

Some of these are: I. pureLiFi™ Company PureLiFi, the home of Li-Fi, is recognised as the leader in the field the usage of the visible light spectrum instead of radio frequencies to enable wireless data communication. PureLiFi provides high-speed wireless access that offers substantially greater security, safety and data densities than Wi-Fi along with inherent properties that eliminate unwanted external network intrusion. In addition, the integration of illumination and

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
