A person can put a lot of metal materials in a house nowadays: metal studs, metal lathe, metal roofing, metal beams. How far can you go before you begin to interfere with using a cell phone inside the house or using a wireless telephone or receiving the internet from your wireless router?

It will vary...from house to house and room to room.

It will vary depending on your location with respect to the surrounding towers.

My house is typical '60s stick built. I have two identical clocks that are supposed to sync with WWV....I can place either one of them in our kitchen...they sync fine with the National Bureau of Standards. I place either one of them in our master bedroom..sometimes they do....sometimes they don't. It is dependent the metal outside your home too.

The house I just bought has steel siding and my cell phone reception is significantly impaired inside the house and I feel its due to the siding. Outside I get pretty good service but I have 2 sweet spots inside the house, besides for those spots usage is pretty much impossible without going crazy. I'm looking at some cell extenders(similar to a wifi access point) to hopefully boost my signal inside the house.

I don't think there's any hope of predicting it. I was in a faraday-cage shielded room a few weeks ago (a room that housed an MRI machine, actually), and my cell phone still worked :confused:. Last week, I was in a magnetically-shielded room (doubled Mu-metal walls) for a different kind of medical scanner, and with the door open, my phone worked. But the number of flat, open spaces without coverage...

A house I owned in California had foil covered insulation in all of the walls, the ability to use rf equipment indoors was not very good.
