OTOH such a weak RF link leads to inconsistent operation. A link that
used to work nicely might quit out of the blue one day just because
someone hung a large white board. The professional ones are aluminum-backed.

Out here the houses that were insulated "extra good" also have
insulation inside some interior walls. This is aluminum backed as well.
For example, I can see the cell tower from here and the signal strength
indicator on the cell phone pegs at the max when in the living room.
Walk into the room next to the garage just a few steps away there is one
wee flickering bar remaining and after a while ... "Not in Service Area".
