Very important:

The researchers suggest white lasers could be used in Li-Fi, a developing technology that uses multiple colors of light to enable high-speed wireless internet access. Currently, LEDs are being used to develop Li-Fi technology, which could be 10 times faster than current radio-based Wi-Fi. Ning and his colleagues argue that Li-Fi using white lasers could be 10 to 100 times faster than LED-based Li-Fi.
