Imagine your internet speed being at par with the speed of light. Now, you don’t need to dream about it because enthusiasts like Harald Haas have made it happen. It’s called the Li-Fi and it works 100 times faster than your existing Wi-Fi system. Li-Fi has been tried out in industrial condition and the results have been encouraging and hopefully you will be able to use this super-fast internet solution very soon. Here’s what you should know about Li-Fi.
What is Li-Fi?
Li-Fi refers to visible light communications (VLC) technology that delivers a high-speed, bi-directional networked, mobile communications in a similar manner as Wi-Fi. VLC is the use of the visible light portion of the electromagnetic spectrum to transmit information. With VLC, data is transmitted by modulating the intensity of light, which is then received by a photo-sensitive detector, and the light signal is demodulated into electronic form, as stated by pureLiFi.
Who Has Made it?
Harald Haas, a Germen-origin professor plying his trade at University of Edinburgh. He is the creator of Li-Fi and his company pureLiFi is making sure the product reaches consumers super soon.
Li-Fi vs Wi-Fi
The internet speed you’re getting now is not bad when you compare it with the situation a couple of decades back. With Li-Fi, however, the equation is set to throttle at a pace that no one could have foreseen. We have always known about the power of light, but to see the energy being used for super-fast data transfer/sharing is very exciting.
- Li-Fi is more efficient than Wi-Fi.
- The energy to access Li-Fi is easily available in the form of bulbs
- It is secured channels of speed transmission
When Can We Use It?
Li-Fi has just made its presence felt after debuting in 2011. It’s safe to say that Wi-Fi is here to stay for a long time but fortunately, Li-Fi could make its public appearance sooner than we think. The dependency on light energy restricts the use of Li-Fi to outdoors and during the daytime. But with the level of pollution escalating across the globe, Haas and Co. need to figure out measures to make sure Li-Fi is a dependable source of internet in the future.
