This presentation discusses Li-Fi technology as an alternative to Wi-Fi. Li-Fi uses visible light communication and can provide higher data transmission rates of up to 10Gbps. It has advantages over Wi-Fi such as higher security since light cannot penetrate walls, high efficiency, and availability anywhere there is a light source. Example applications discussed include underwater communications, internet access from street lamps, traffic safety/management systems, and indoor location tracking. While Li-Fi signals cannot penetrate walls and require line of sight, it could enable a cleaner, safer wireless future if more widely implemented.
