RONJA-Wireless Internet via Visible Light Link

[LaughingCheese]

Thought this was pretty cool. Bookmarked it a while ago and recently rediscovered it:

It uses two high powered light sources as transmitter and receiver.

It has a range of about 1km and can get speeds equivalent to wired Ethernet at 10Mbps.

That's wayyyy better than my wifi !

Although the AP I connect to is on the other side of the next room behind a wall.


What's even cooler is that the device is totally open source, meaning anyone can build with it, tinker with it, etc.


Would be interesting to see what kind of speeds a laser could get, since this device can be interfered with by weather, though I'd think a laser would be affected too.
