Velmenni, a startup dealing with communication technologies, has used this concept to create Li-Fi — a Wi-Fi network that uses light as the medium to transfer data between the router and the device. So, how can you increase your Wi-Fi network’s speed, given that the current medium of data transfer is electromagnetic waves? It’s simple — use a faster medium, which in this case is light.For using a Li-Fi network, mobile devices to need to use an adapter that can understand light signals. However, Deepak Solanki, CEO of Velmenni, says that the system will be able to provide network speeds of up to 100Gbps. Therefore, next time when you are flying on an Airbus aircraft, enjoy the in-flight illumination while streaming your movies faster.A tech car park lighting factory startup has come up with Li-Fi, which uses light as a medium to transmit data to and fro from a device. This blinking of light happens in a few nanoseconds, which means that the human eye won’t see the room light flickering while using the Internet.
Li-Fi replaces the radio waves with light. Although Li-Fi has a potential to make the Internet more accessible through Wi-Fi-like networks, the biggest benefit will be available to the aviation industry — Airbus is looking to implement Li-Fi connectivity in their aircraft, reducing the bulk of wiring required for passenger entertainment systems. However, increasing the bandwidth of the connection between the tower and the device is good for those who are ready to shell out a substantial amount of fees for it; what about those who want to experience faster Internet speeds on a lower budget? The most economically possible answer is using a Wi-Fi network. Presently, the prototype adapter is bulky, which the company says will shrink in the coming days. Li-Fi uses light signals to send information digitally — switching the lights ON and OFF, representing the binary codes of 1 and 0.(With inputs from Australian Business Traveller)(Also published on Deccan Chronicle)end-ofTags: wi-fi, internet, connection.For using a Li-Fi network, mobile devices to need to use an adapter that can understand light signals. Light as a medium is already used in fibre optics — only this time, it is used wirelessly to send and receive data between devices.
With every advancing year, we have been looking at faster Internet speeds across the globe.Currently, Li-Fi can achieve network speeds of up to 1Gbps right now.However, Wi-Fi routers are limited in speed, which slows down the experience when multiple devices are connected. As for the router, “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,” Professor Harald Haas from the University of Edinburgh, said during a TED talk.The concept is easy to understand — the present Wi-Fi routers use radio waves for sending and receiving information. The technology is currently under development with Airbus. We have only grown used to LTE network speeds and 5G technology is already looming on the horizon, waiting to fasten up the Internet with speeds up to 5Gbps. Harald is one of the key persons behind Li-Fi.
