Depends on your modulation technique. You should be able to get up to dialup and maybe even ISDN speeds out of the gear at the least [snip][/QUOTE]
Well, that's just out of my league. I'm a NAS and network fan, but my background is law, not electronics, so I'm going to take your word on it... hehe
Still, it does seem an awful lot of work to setup on the hardware level. WiFi, though "heavy-duty", seems easier, since it basically involves modifying router firmware, which is only really needed for extra-long links, anything under 10Km should be fine (but again, that's from a non-tech perspective).
I think it boils down to the application. Disasters need portability, community links not so much.
The biggest problem with this setup is you've got to modify the routers or the network stack in the R-Pi's to even have a chance of it working- combined with those HUGE dishes.[/QUOTE]
As I said above, only extra-long links require firmware hacks. Other than that, you only really need AP-to-AP bridging support, which is not that uncommon.
Ronja does need a manual Full Duplex link, though, which might be hard to achieve with standard networking switches...
Ronja's would be nice for some configurations. Won't argue it. I think, however, they never got the 100Mbit model done. Not wholly sure why unless it just didn't prove out to work as well as planned and they had to re-think things- and then never got back to it for personal life reasons.
A few years back, before the site redesign, the Ronja creator clearly stated his goal was to get a dirt-cheap design and final product, using the least expensive materials available (the lenses used are from standard magnifying glasses, just to name one example).
While there is always the chance the "personal life reasons" is true, I think there might be a chance the laser design was just too expensive to achieve, either because of PCB, components, or something else, and so it was scrapped.
I do think there is still a small reference on the Donors page to the laser component, only thing is the whole site seems to have been abandoned...
Anyway, idea exchange is very interesting. It has been a while since I've done this...
