What do these things use then? IR LEDs or something? <br>
I think they would be susceptible to some interference from the Sun and
heavy
rain/fog, so not completely noise free, but at least you don't have to
share with phones and microwaves. :)<br>
<br>
You might be able to convince someone like Jaycar to set the kits up,
especially considering they're completely open source designs.<br>

... ok are they REALLY called Korunas? Sounds a bit too much like
kahunas to me.

<pre wrap="">Yeah, I like it a lot. Doing a currency conversion from Czech Korunas
to Austalian Dollars shows that one of these units could be built for
between $90 - $140.
Features:
* Point-to-point - almost impossible to eavesdrop upon (without major
effort on the part of the eavesdropper)
* No licence required - no frikken' lasers!
* Interesting project - a different and still affordable approach to
wireless networking.
Compared to 802.11b:
Advantages
* Not 2.4GHz - not susceptible to interference from users using the same
gear/spectrum, no hidden node hassles.
* True 10Mbit/s full-duplex speed
* Fairly cheap
* Easy to build for someone with basic electronics skills
Disadvantages
* Fairly short range (1.4km)
* Time consuming to build, not available pre-built or even in kit form
yet.
* Not capable of point-to-multipoint operation
* Strictly line-of-sight
I'd be interested to see if there are ways to legally increase the range
of these babies. Then they'd be a real viable option for backhaul links
on a network such as ours.

Very interesting, having a look through now and it looks like it could
be a lot of fun to build, although i'll have to get someone to make
