- Examples
-
Since Li-Fi uses just the light, it can be used safely in aircrafts^([sic]) and hospitals that are prone to interference from radio waves.
The beauty of Li-Fi is that it uses existing infrastructure, avoiding the need for thousands of radio masts, as the current spectrum requires.

The vision is that a Li-Fi wireless network would complement existing heterogeneous RF wireless networks, and would provide significant spectrum relief by allowing cellular and wireless fidelity (Wi-Fi) systems to off-load a significant portion of wireless data traffic.
