Just a couple of small points here.

When I use the term "broadcasting" I am not using a legal definition  
but a simple technical one.

Your mobile phones, radios and TVs would cease to function as well.

Yes, me but I was not referring to any change in the transmitters, the  
local household equipment.  What I meant was that with small changes  
in the receiver, normal household wifi can be received at great  
distances.  It may not necessarily be joined at distance but it can be  
received.  It is leaking far further than most people realise.
