[100 Times Faster Data Transfer Than Wi-Fi]

Wi-Fi has really changed the way we interact with our devices. By eliminating the need for wires, this technology provided an additional element of mobility to our electronic interactions.

However, there are still a lot of limitations in speed and range when it comes to working with Wi-Fi connections. In order to catch up with the hi-speed demands of both the users and content providers, a new technological development is need in the field of internet connections.

This development has come in the form of Li-Fi, a brilliant technology which uses actual light to transfer data at speeds which are up to 100 times faster than existing Wi-Fi devices.

Li-Fi, which was invented in 2011, by Harold Haas of the University of Edinburgh, uses visible light communication (VLC) to send data. It works like a signal lamp, flashing on and off in order to relay messages in binary code (1s and 0s), but at speeds so fast that the naked eye can’t even recognize the flashes.

This technology, when initially tested in lab-based experiments, showcased the ability to transmit data at speeds of up to 224 gigabits per second.

Real life testing for this technology, done by an Estonian start-up by the name of Velmenni, showed more modest results, in the form of 1 gigabit per second. These results are still far superior to Wi-Fi connections, which can only achieve speeds of approximately 600 megabits per second.

The great thing about this technology is, that all you need to do is place a small microchip inside regular LED bulbs to turn them into your own personal Li-Fi devices.

We hope that the research for this technology is completed ASAP, so that we can enjoy a new way of accessing the world wide web.
