You cannot always count on windows being a good portal to
the outside, wireless word.  Most new'ish windows these days
use "Low E" glass.  Low E glass is essentially standard clear 
glass with a microscopic, transparent, metallic coating on its 
surface that is better at reflecting heat than the glass itself.
The coating used in low E glass tends to be that of a 
low-emissivity metal, such as silver.

Add to that the Faraday effect that a stucco siding presents,
and you'll understand why it can be frustrating to use a 
cell phone inside my home.

And then there are the metal roofs adding to the mix with
GPS devices....
