HYPOTHESIS I hypothesize that all of the materials listed in the previous slide will decrease WiFi signal strengths, but the glass will have the least effect. Glass will have the least effect on the WiFi signal because it allows the low frequency light to pass through. I think that the metal door will have the greatest effect on the signal because it does not let as much light energy through. What materials reflect signals? What materials absorb signals?
Worst Signal Loss: Concrete. Concrete, with and without metal reinforcement, is one of the worst building materials for wireless signals to pass through, but masonry block and bricks can also be serious barriers for Wi-Fi. Least Signal Loss: Plywood and Drywall. Plywood and drywall come close to zero signal loss in tests. By the Numbers
