Project Ronja

A couple of days ago while visiting some wireless forums I came across this link: Quote from the website

What is Ronja?

Ronja (Reasonable Optical Near Joint Access) is an Free Technology (like Free Software) project of optical point-to-point data link. The design is released under the GNU General Public License: you get all the necessary documentation and construction guides free. The construction costs are minimal; it’s probably the cheapest wireless system ever. The operation is reliable and immune to interference.

So someone can create cheap point-to-point links just with optical technology. The materials needed (not the tools) cost less than 100E to create a receiver and a transmitter. What’s really shocking is the speed of these links..10Mbit Full Duplex with simple led lamps. It might be possible to change the led and the circuit to gain in distance and/or in speed. And that’s what me and some friends from the university will try to do. Unfortunately I have no idea to help with electronics…so my only contribution in the beggining will be ideas and money.

I hope we finish this sometime because it’s both interesting as a project and usefull. Wireless noise inside cities is steadily raising…it wouldn’t be bad to replace some backbone links with a couple of these…if they work as expected. And why shouldn’t they….a lot of ppl use them alredy.
