Introduction LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. We reviewed and executed two projects that we had aimed would display the technology in its essence and most simple form. Also, LiFi is said to increase bandwidth by 100 times what we have today with WiFi. Using the fact that data is nothing more than just fluctuations of current in logical 0’s and 1’s, Li-Fi uses these two states to send data. Wi-Fi or Wireless Fidelity has been the standard of convenient data communication more than three decades. This makes our waves taller and higher energetic since frequency is related to the energy of the wave and this further causes the waves to be more readily absorbed by air molecules. He spends a lot of time watching movies, and an awful lot more time discussing them. We used this simple experiment to demonstrate the application of such technologies in self driving cars of the future and how through the headlights of existing cars we could control vehicles in traffic and transmit data. However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission. This is expected of radio signals and to explain this phenomenon in very general terms we must recall a standard formula of electromagnetic waves: V= f (lambda). How Do Different Types Of Telescopes Work? Abstract: This paper attempts to clarify the difference between visible light communication (VLC) and light-fidelity (LiFi). It’s simpler than it looks. Knowing the fact that audio transmitted through such cables are nothing more than current fluctuations that were modulated and demodulated by sources and speakers respectively we decided to exploit this fact by attaching an led to the source aux cable and a solar panel, a photoresistor that could receive such fluctuations, to the receiver cable and demonstrated how analog signals can be transmitted through Li-Fi. LiFi might not only give 5G a data speed run for its money, but could actually be the answer to many of the questions posed at the fifth-generation wireless technology. In this LiFi technology, Visible Light (LED bulb light) is used in Digital Information Transmission. This is a trend that we can be assured will continue as our routers expand to newer frequency ranges and this is not sustainable.

This incredible feat is only possible because a LiFi connection can transmit data at the rate of 224 gigabytes per second! Since the speed(V) of all electromagnetic waves remain the same in the same medium, the wavelength of the wave must decrease proportionally to compensate for the increase in the frequency of the wave so V ( the speed) can remain the same. The first car was completely controlled by a remote control and had proprietary software -that was coded from scratch- that would modulate an LED according to the signal it had receive. How is that possible? That means no Internet while lying in your bed at night. What Is The Fibonacci Sequence? However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission.
