Hi Jack,
There are two popular off the shelf systems currently sold in New Zealand.
Trango is one, Motorola Canopy is the other. Both are available in
.9/2.4/5.3/5.8GHz frequency bands, and both have unique advantages and
drawbacks. You could also go down the path of Mikrotik or StarOS, or other
of the myriad wireless ethernet based systems. You might find these less
expensive in terms of hardware, and you might find them more expensive in
terms of administration.
Whatever you choose, please assume that you'll be sharing spectrum with
other users, and plan accordingly.
Here is some unsolicited planning advice for the new WISP. (Attention! This
advice is not from any company I may work with/work for/own shares in/go
drinking with, etc., read on at your own risk, and may peace and harmony be
with you.)
Both Trango Fox and Motorola Canopy subscriber units can be purchased with
small parabolic reflectors. This tightens the subscriber beam width from
30-60 degrees (by default spraying unwanted radio everywhere) down to 9-10
degrees. Please use these reflectors, and remember to turn the subscriber
unit radio power down accordingly. Your network will run better, and your
neighbors' networks will run better.
With any system you choose, use external base station antennas. Buy a good
quality sector antenna (slotted waveguide made from drain pipe does not
qualify) and ensure you have it physically tilted down. If your most distant
customer is 10km away, please make sure you're not pointing your antenna
where someone 30km away is going to hear your noise. This will benefit you
too - your AP will be hearing your subscriber units and not SUs from the
next town over.
Good luck.
Cheers,
Jon

Hi all,
Currently planning on setting up a community wireless project
in South Taranaki.
Range is looking to be up to 10km from the AP's.
At the moment I'm looking at using Trango Radio Units [1] and
was after thoughts/comments on this choice...
Cheers,
Jack
