Which would be the most authoritative source?    IET or BBC?   and guess where the BBC points to!

What is easier for the public to understand though.

Link wars!  This is a new one!

Range 10m (free air).

So probably only useful within the same room as the access point.

Shame its way behind consumer DSL and fibre speeds though but not if you are a corporate or ISP.

Wavelength is only about 600 microns, so a parabolic dish is an obvious candidate for point to point links, eg an "office" at the other end of a garden.

The article doesn't mention the radiation pattern of their source so accurate answers aren't possible, but some rough estimates and back of envelope calculations indicate a ballpark range of 300 metres or so with a 30cm dish, which is a lot further than Cat5 ethernet will give you

True. But it helps for things like wireless TVs, Screens etc. At those speeds, you could even start offering wireless PCI cards etc. No "plug and play" just "drop it off on the desk and play"
