certainly it has distance advantages and point to multipoint advatages and possibly cost advatages as well.

however wifi also has it's disadvatages. For a start the 11mbs (for which you need a _good_ signal) give a throughput nearer 5mbs in reality.

interferance issues are another disadvantage

As far your link goes - I am sure they were not operating within the UK legal limits of 100mw EIRP. You just can not get that sort of range within 100mw EIRP - at least as I understand it.

For me affordable (read - build your own) free space optics complement wifi / wireless and wired options for community / self built networks and as such I welcome the ronja project.

Now all I have to do is find someone willing to build me one
