Best to go with steel studs -- it's found in all modern commercial buildings where I live. Use steel joists between floors and a metal roof and you've got yourself a building full of tenants who have great wifi, but terrible 4g cellular. https://www.scafco.com/wp-content/uploads/2017/09/iphone-bac...

Interesting, thanks for the reply. I was thinking the rebar and metal straps might act to block signals, but I guess not.
