Li-Fi innovation : What is it and how does it work?

Li-Fi Has Just Been Tested in The Real World, And It's 100 Times Faster Than Wi-Fi

What is LI-FI?

Li-Fi (or light fidelity) is an innovation for remote correspondence between gadgets utilizing light to transmit data. In its present state just LED lights can be utilized for the transmission of visible light.

Li-Fi utilizes basic light transmitting diodes, lights to empower data exchange, boasting speeds of up to 224 gigabits for each second

Difference betwn WI-FI and LI-FI

the innovation is like Wi-Fi. The difference is that Wi-Fi uses radio frequency to transmit data. Utilizing light to transmit data permits Li-Fi to offer a few favorable circumstances like working crosswise over higher transfer speed, working in regions vulnerable to electromagnetic obstruction  and offering higher transmission speeds. The innovation is currently being produced by a few associations over the globe.

It is anticipated that future home and building computerization will be exceedingly reliant on the Li-Fi innovation for being secure and quick. As the light can't infiltrate through dividers, the signal can't be hacked from a remote area.

Rather than radio recurrence waves utilized by Wi-Fi, lights can't enter through dividers and entryways. This influences it more to secure and makes it simpler to control who can interface with your network. As long as transparent  materials like windows are covered, access to a Li-Fi channel is restricted to gadgets inside the room

These are some  companies and organisations that are developing this technology:

pureLiFi  - Lucibel  - VLNComm - OLEDComm - ByteLight

Professor Harald Haas, Chair of Mobile Communications said:

"All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission,... "In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fis deployed worldwide for a cleaner, greener, and even brighter future."
