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?
The performance of a Wi-Fi wireless network connection depends in part on signal strength. Between a computer and wireless access point, the signal strength in each direction determines the data rate available on that connection.Answer: To determine the signal strength of your Wi-Fi connection at any point in time, use one or more of the following methods:1  Operating system utilities-Microsoft Windows (and other network operating systems) contain a built in utility to monitor wireless network connection status. Wi-Fi locator devices-Resembling a keychain, a Wi-Fi locator device is designed to detect signal strength of nearby wireless access points. 2  Most Wi-Fi locators use a set of between four and six LEDs to indicate signal strength in units of bars similar to the Microsoft Windows utility.
