LiFi is a wireless technology which uses a light-emitting diodes (LEDs) for the transmission of data. Lifi is a technology which is used for transmission of data through illumination by taking the fibre out of fibre optics by sending data through a LED light bulb. The varies in intensity faster than human eye can fallow. Lifi is a very cheap and fast wireless communication system which is optical version of the WiFi.
How LiFi Works:
Operational Procedure is very simple, If the led is Activated, you can send a digit number ‘1’, if its disabled you transmit a ‘0’. The LED’s can be easily switched OFF and ON very quickly, which gives nice opportunities for sending the information.
Hence all that us required is some light emitting diodes and a controller that code data into those LED’s. Then we have to just vary the position at which the LED’s flicker depending upon the data we want to encode. Thus every light source works as a hub for data transmission.
LiFi stands for Light Fidelity and it is implemented to use LED light sensors(in the form of bulbs) similar to those presently use in many energy-conscious homes and offices. Although, Light fidelity sensors or bulbs are outfitted with a chip that emittes the light undetectable for optical data transmission. LiFi information is transmitted by the LED sensors and received by a light-sensitive cell called photoreceptor.
LiFi’s early developmental models were capable of 150 megabits-per-second (Mbps). Some official kits activating that speed have been released. In the lab, with stronger LEDs and different technology, researchers have enabled 10 gigabits-per-second (Gbps), which is faster than 802.11ad.
Benefits of LiFi:
1). LiFi is having High speed than Wi-Fi.
2). 10 thousand times the frequency spectrum of radio.
3). security is more, because the data cannot be intercepted without a clear line of sight.
4). Prevents piggybacking.
5). Eliminates neighbouring network disturbances.
6). Unimpeded by radio interference.
7). It is possible to send more than 10gbps, theoretically allowing a High-definition film to be downloaded in 30 sec.
8). mostly powered by the LED’s, so cost is efficient.
9). Transmission of data is easy and fast.
Smart Urban communication:
Create your LiFi in 3 steps:
It is very easy to create the Light fidelity technology in 3 steps.
1). Install the LED lighting that fits to you.
2). Add our Lifi key to your mobile devices.
3). Download LiFi application on your Play store Apps portal or contact us to develop your own customized application.
