LiFi – The Future after Wifi

WHAT IS LiFi? Light Fidelity or LiFi is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds. LiFi uses common household LED light bulbs to enable data transfer, boasting speeds of up to 224 gigabits per second.LiFi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves while LiFi runs on visible light. As we now know, Li-Fi is a Visible Light Communications (VLC) system. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into ‘stream-able’ content. HOW...
