Maximum speed of Li-fi is tested 100Gbps and it can be upto 240 Gbps theoretically. The history and challenges of wireless communications, as outlined in previous chapters, suggest a variety of strategies that could be pursued to fulfill the vision for untethered military communications systems. Li-Fi is perfect for use in military bases. While there are, in practice, still some hurdles to overcome, the lab results are very promising and in some applications the technology has already proven the capabilities. Conclusion The benefits that you can gain from LiFi is immense. It uses the visible spectrum of light which is far better than the RF as it is prone to interference. History of Networks In the olden days, people formed a network in orderto transmit a piece of data from one place to another.

Visible light communication (VLC) eliminates the risk of some disease caused by the Radio waves due to long period exposure. Li-Fi C only function If the light source provided is continuous and uninterrupted. You can make your own amplifier circuit to improve the voice quality like shown below. So what is LiFi? As soon as you play the audio, you will see that there is frequent change in intensity of light. This will help to make underwater communication much easier. It is obvious that you need to read *a lot more* and to clarify for yourself many things, I hope you complete your mini project and learn new things and clarify the things that are not clear to you now. Audio signal *IS* an electrical signal. Every time we pressed a button on our Television remote the IR LED in the Remote pulses very fast this will be received by the Television and then decoded for the information. Wi-Fi networking faces problems of neighboring network interference or radio interference whereas Li-Fi is free from all types of interferences that could affect Wi-Fi system and are therefore more efficient for use. Solar panel is so sensitive that it can catch small intensity change and correspondingly there is change in the voltages at output of solar panel. It works on the principle of Visible Light Communication (i.e. 2. A 10K Ohm resistor and a 10μF capacitor is connected in series between pin 7 and ground to decouple the audio input signal. Introduction LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. With the advances in technology a new mode ofnetworking was developed by using the wires as amedium (wired networking). LiFi Project Demo LiFi Data Transmisison. nothing new here , a friend did this in 1980 as a school project , used a bicycle lamp as the source and a photocell as receiver.

Both the technologies LiFi and WiFi co-exist together based on their respective unique features. Li-Fi can be used in traffic lights to update drivers on weather conditions and traffic information so they can have a smooth journey on the road. As time passed the technology increased and welaunched satellites into space and thus were in … This is believed to be the next generation of internet, where Light will be used as a medium to transport data. Our aim is to provide cool & unique stuff and gadgets that you are unable to get it in a retail store or other online stores (or due to high prices) at unbeatable prices & Quality as well. quality and range can be improved by using Frequency moduclation (FM as in vhf radio) of the signal , Totally different from the "LIFI" it is pretending to be. LiFi can become a great communication method for home networks, for example, to transfer data from one computer to another, or to stream high definition movies from your home media station. Electronics lovers is a true place for the student and engineer or hobbyist to surpass within the field of electronics design. quality is not good or range . If this technology can be put into practical use, every bulb can be used something like a Wi-Fi hotspot to transmit wireless data and we will proceed toward the cleaner, greener, safer and brighter future. The technology has evolved so much that everything from our car to our refrigerator needs a connection to the internet. It cannot, therefore, function without a continuous light source. However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission. First, data is fed to the LED bulb. Here we are using Solar panel at the receiving end to sense light. 4 Conclusions and Recommendations. Reasons Why We Don’t Have One Commercially Available Yet, Sanjeev Sharma, CEO of Swaayatt Robots on How They are Building a Robust and Scalable Autonomous Driving Technology without the Use of Lidars or Radars, MPPT Solar Charge Controller using LT3562, How to Build a High Efficiency Class-D Audio Amplifier using MOSFETs, AJAX with ESP8266: Dynamic Web Page Update Without Reloading, Build a Portable Step Counter using ATtiny85 and MPU6050. Li-Fi can help in keeping up with the demand if wireless data networking. The Use if Li-Fi here is therefore very useful. The data transmission here will be very fast than RF. In 2013, the first product, the Li-1 was launched.
