I Think I Figured Out My Wireless Issues — I Am Living in a Damn Faraday Cage

Posted by on | August 26, 2017 | Comments Off

I have always had a couple of frustrations in my house.   First, we get awful, almost non-existent cell service from both Verizon and AT&T, despite living right in the middle of the city.  I always chalked this up to be on the outskirts of an area of town that until recently did not allow the construction of cell towers.

The other problem I have is trying to get a wireless signal through my house.  While the house sort of sprawls, it is U shaped with distances such that it should not be impossible to send signals from one side of the U to the other.   But it always has been hard, thus my investment in a commercial grade wifi system.

The other day I was watching a contractor cut a hole in the outer wall of my house, which is covered in stucco.  I hadn’t really thought much about the home’s construction — it has some cinder block but mostly is just wood frame.  But watching the construction I had an epiphany.  The stucco was put on in the old way, over chicken wire.   I hadn’t thought of this because none of the new stucco I have ever seen going on is done this way any more.   It turns out my whole house is covered in a big net of chicken wire.  Worse, I saw they had removed the stucco around one of the hose bibs and the chicken wire was wrapped around the metal piping, the same piping our house uses as a ground.  My whole house turns out to be covered in grounded chicken wire — I’m living in a Faraday cage!

Obviously since the wire does not cover every surface (windows, roof, etc) and was not carefully constructed to be a Faraday cage, the effect is not perfect.  But I took some measurements.  Wifi signal strengths in the 2.4Ghz range dropped by about 7-10 db when passing through an interior wall but dropped between 20 and 30 db through my exterior walls.

So at least I have some idea, finally, of what might be going on.
