After Success of wireless data transmission technology Wi-Fi, scientists are coming with a new age technology Li-Fi . Li-Fi is a lot faster than what we are currently getting from Wi-Fi. In lab conditions, researchers claimed to achieve the speed of 224 Gigabits per seconds by teasing Li-Fi is capable of sending data up to 1GB per second which is 100 times quicker than average wi-fi networks
What is Li-Fi ?
Li-Fi is the transmission of data through illumination by taking the fiber out of fiber optics by sending data through a LED light bulb. This varies in intensity faster than Human Eye can follow. It is the fast cheap wireless communication system which is optical version of the Wi-Fi.
How Li-Fi Works ?
Operational procedure is very simple, if the led is on, you transmit a digital 1, if its off you transmit a 0. The LEDs can ben switched on and off very quickly, which gives nice opportunities for transmitting data. Hence all that us required is some LEDs and a controller that code data into those LEDs. We have to just vary the rate at which the LEDs flicker depending upon the data we want to encode.
Thus every light source will works as a hub for data transmission.
Advantages of Li-Fi.
- It is possible to achieve more than 10 Gbps, theoretically allowing a high-definition film to be downloaded in 30 sec.
- Mostly powered by LEDs so it is cost efficient.
- Transmission of data is fast and easy.
- Its main advantage is it’s Bandwidth is 10,000 times than the radio waves.
