1W is good for 3 or 4km in perfect conditions, I'm guessing most WISPs need to cover larger areas than this. The max output power at 5.8Ghz also appears to have been reduced - it is now max. 4W (good for about 5 or 6km). So presumably much of the gear WISPs have been using won't be allowed anymore e.g. Trango's with dishes, etc. This might be good news for WISPs operating small metro networks, but it is bad news for anyone covering large rural areas. Basically, operating a reasonable size WISP has just got a lot more expensive.
Cheers,

No, the 4W/200W PTP maximum power hasn't changed as far as I'm aware. http://www.rsm.govt.nz/licensing/frl/information.html still shows 4W and 200W max on 5.8Ghz. 5.4Ghz not on that page yet it seems. The whole point of opening 5.4Ghz is for lower power short range communications, in crowded metro centres where currently there is a lot of contention for 2.4Ghz and 5.8Ghz spectrum. More mini POPs, covering shorter distances. This is not going to help in the instances of needing to cover 6-10KM and further ranges, for which 5.8Ghz/2.4Ghz is still much more suited. Cheers, Blair
