Li Fi technology, an introduction
With the use of light radiating diodes Li-Fi technology transfers data through wireless. Li-Fi is a new exemplar for photosensitive wireless technology to provide unprecedented connectivity within a localized data centric environment. There has been a complete shift in wireless technology due to increase demand for faster and more secure and protected data transmission.
Li-Fi is such a free band which is license free that is why it is less at cost than Wi-Fi. With the use of special intonation using a distinctive signal processing technology thousands of streams of data can be transferred simultaneously at higher speed. Li- Fi is useful in aircraft because the lights present above head can be used for data transmission. It is useful in controlling traffic at traffic signals as it communicates with LED lights of cars. Where there is difficult to amateur optical fibers LI-Fi is used.
The new Li-Fi technology can be well managed very easily and it is pretty simple. At one corner you will be having a led which will be working as a light source and on the other corner a Light Sensor or a photo detector. Light Sensor detect light as soon as the LED light starts glowing and will give an output of either binary1 or binary0.
We prepared and published this seminar abstract for final year engineering students seminar research. You should do your own research additional to this information before presenting your seminar.
Hello Sneha, that is a good question. Incandescent light bulbs or fluorescent lamps do not work on that speed like LED can, this is my reading. Additionally, the way they work as compared to an LED is totally different.
