Li-Fi might not need line of sight, some experiments were thrown around showing a 70 Mbps transmission rate with light reflected off walls and other surfaces.

Li-Fi might not need line of sight, some experiments were thrown around showing a 70 Mbps transmission rate with light reflected off walls and other surfaces. Which, obviously, is a large step back from the 224 Gbps claims for direct line of sight communications, but could still be interesting to e.g. replace ZigBee in IoT devices.
