Who would've thought your lamp could replace your router?
Since light bounces off walls and is thus confined to individual rooms, there is less interference and higher bandwidth, and traffic is harder to intercept from outside.
Aren't radio waves and light waves the same thing? Either this is in the visible spectrum and thus annoying as hell. Or it's just marketing's way of selling the decreased indoor-range.
But, if light bounces in every obstacle, it will be confined to just a room or so... Then, I think is unreliable for the general public and will be only useful in specific situations... Which I can't think of a single one... Not getting interference with Military, Hospitals and Airplanes isn't already achieved by separating special frequencies for WiFi and Bluetooth? How that is achieved today?
It's interesting and I'd definitely like to see how this develops. What I'm worried about is interference from monitors and sunlight
