Re: (slightly) offtopic- radio modems

[Tim Hurman <kano-tlug@example.com>]

If you have line of sight and not many trees/radation absorbing materials
in the way, you may be able to use wavelan (IEEE 802.11). You would
probably need a directional aerial though. If you can get them, Lucent
technology's gold cards are very nice, and they support a 128 bit (IIRC)
encryption keys.

However I would not take my word on this as I have not tried wavelan up to
this distance, pull up some spec and so the calculations before investing.
One thing that might be of help is that on some of the American wavelan
cards you can apparently bump up the power o/p.

Or for the more technically adventurous, laser transit, as used on
"Sealand"? :)
