Li-Fi (Light-Fidelity) is a wireless communication system that modulates the intensity of light (usually from LEDs) to transmit data; hence light itself is the transmission medium. Lab demonstrations have achieved data rates in excess of 1 Gbps—many times faster than conventional Wi-Fi—so both statements are accurate.
