Indeed, but I was just questioning if the 'rules' covered power to the

With most things RF and goverment rules its radiated power that counts,
that way it covers antennas with gain.... crafty blighters !!

I suppose a problem with that could be 'how' that signal is radiated and
how 'close' to the upper tested limits the manufacturers sail?

ie, One make / model of WiFi kit is 'known' to work better (afa range lets
say) than may others? Or have more options that may help propagation.

Ignoring the risk to humans from microwaves, I think what should be
important to those who set the rules is what proportion of signal get's
out past my boundries. Ie, if I lived in a Faraday cage I could (should be
able to) use whatever power I like ;-)

So, if I want to get a signal down to my workshop I should be allowed to
do whatever re the (max) power available (I'm talking antenna here) as
long as the rf that actually makes it out of my house is below the
permitted maximum?

I know the above is pretty unworkable in the real world but you get the
idea ...

Thats why most things come with very ineffecient antennas and are ltd to
low power. Even Faraday cages can leak!!
