[AusNOG] AirFibre

[Paul Wallace]

That's probably right ... I know of one test that took place in Silicon Valley over 32kms @ 80GHz

80GHz is great for connecting full duplex Gb services (and even 2Gbs these days heading up to 10Gbs soon as well) but only up to 5kms in Qld & NSW weather.

To be fair that vendor was trying to win a theoretical argument that 80GHz doesn't completely dissipate over that distance.

They reported that it formed a link & operated at feel speed which is quite amazing when you consider the 80GHz wavelength is only 3.75mm long!

Remember that the US rules for operation in their similar band are less restrictive than ours but still low.

Bear in mind there's a chance that in theory you could actually successfully form a link at 13kms, ... on the basis that 24GHz does not completely dissipate over that distance, however rain would cause serious failures.

I always assumed that these kind distances existed in only very contrived situations (between two mountains in Death Valley etc), for marketing purposes only. Bit like peak throughput figures for routers.
