| Faraday cage... Yea, most people see a home as just walls, doors, windows, roof, but within those walls are electrical power wiring, which unless shielded in conduit emit an EM field about a foot or more in diameter, screws, nails, phone cables, and some folks like me have aluminum siding, and then there's the extremely frustrating prospect of having a house built too close to a rich iron ore deposit, which can block even over-the-air broadcast signals for tv let alone a weak indoor system like wifi. Add to that all of the interference caused by appliances and other devices, and you might begin to see why cell & wifi might not work so well indoors, even without plaster (which can block radio by itself depending on the type) & lath walls in some locations.
