Li-Fi will make your internet 100 times faster

A new innovation has stunned the folks around the globe. The innovation has predicted an era where wireless data communication will be done through light. Li-Fi is what we are referring too. Light Fidelity which was in tests for few months now has shown promising results in its practical application. With Li-Fi, wireless communication will be done on visible light waves rather than on radio waves.

Amazing! Is not it? The people behind this great concept has taken idea from the concept of the Signal Lamp that sends morse code between ships at sea. They has evolved the concept and made a light bulb that sends data to mobile phone within the light range. Li-Fi has also been termed as visible light communications (VLC) technology.

Nowadays, Wi-Fi networks are getting congested because of the limited spectrum of radio-waves. But with Li-Fi, this is not gonna be case at all. A visible light spectrum is 10,000 times bigger than the radio waves. This means 10,000 times more large number of people can enjoy internet in same area through Li-Fi. Also, we all know that light waves are the fastest. The demonstrations done by the team behind this technology has shown speeds of around 1 Gbps i.e. 100 times faster than average Wi-Fi data speed. In laboratory tests under controlled environment, the speed can be even upto 224 Gbps.

Li-Fi technology will not use old bulbs. Instead, it will operate on LED bulbs that have more intensity. The light detecting technology will be incorporated in smartphones. Thus, as you turn on your LED bulb and switch the toggle for Li-Fi network ON in your smartphones, the connection will establish. It’s just like how your TV remote communicates with television.

One of the other highlight of this Li-Fi technology is its security. As light remains within walls, it can help developing a concentrated network within an area. This will certainly be making the interception of such network difficult. Moreover, light waves also don’t get dispersed by wind. This characteristic promises the stability of networks under this technology.

The company behind this freaky idea is Velmanni i.e. an Estonian startup firm. They expect that Li-Fi technology can be made available to customers within three to four years. One of the major drawback of Li-Fi is that it can’t be used in sunlight or in areas where are other interfering light sources.

In the future, we can expect that both Wi-Fi and Li-Fi will be used simultaneously. While Wi-Fi will be used for normal internet, Li-Fi will be for more centered and focused connections like in offices, shops etc.
