Yes But
BT has the most powerful WIFI according to their adverts, so with a helicopter (and someone hanging off it) or a drone, their most powerful signal will go for miles!!
Seriously this has been take up by SKY & Virgin with the ASA, but to no avail AFAIK, so Joe Public will blindly buy BT's stuff.
Perhaps it will all change next month when the OFCOM rules come in?
Wheeeee Flying Pig
