Li-Fi, invented by the University of Edinburgh’s Harald Haas. Haas was able to demonstrate that a single LED light bulb could transmit more data at a much higher speed than a cellular tower back in 2011. “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,” Haas said. “In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fis deployed worldwide for a cleaner, greener and even brighter future.”
LED light flicks on and off at such extreme speeds that it can be used to write and transmit things in binary code. Li-Fi is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi.
Velmenni CEO Deepak Solanki told IBTimes UK: “We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology.
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.”
Advantages of Li-Fi over Wi-Fi:
- Less Interference
- Higher Speeds
- Higher Security
- Low Over-head
