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?
After explaining how there are several components that make WiFi, you can see how naming a single inventor would be difficult. First, let's take a look at the history of the 802.11 standard (radio frequency) used for broadcasting a WiFi signal. Secondly, we have to look at the electronic equipment involved in sending and receiving a WiFi signal.
