New Li-Fi technology is 100 times faster than Wi-Fi

High-speed data using visible light communication

New alternative technology
A new technology called Li-Fi (Light Fidelity) promises connections up to 100 times faster than Wi-Fi. According to researchers, the new alternative technology transmits high-speed data using visible light communication, which would reach speeds of 1 Gbps, which is about 100 times faster than a standard WiFi.

Created in 2011, the transmission via Li-Fi is made using LED lights, which flicker on and off so fast that it is completely imperceptible to the human eye. Li-Fi could, ofr example, allow users to download an HD movie in a few seconds.

“We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology,” Deepak Solanki, CEO of Estonian tech company, Velmenni.

“Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light. We are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the Internet in their office space.”However, Velmenni was not the only company interested in bringing Li-Fi to the real world. Other names, such as Oledcomm and pureLiFi by the creator of technology Harald Haas, are also working to commercialize the technology. As Li-Fi is based on light, it cannot go through walls and would have a more limited range than Wi-Fi – which also means greater security.
