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?
HIGH FREQUENCY SIGNAL ATTENUATION THROUGH MATERIALS M. SCUTARU 1 P. OGRU Å¢AN 1 Abstract: Due to the growth of high-frequency signal usage in recent years, limiting the coverage of these signals in the common household environment has become an issue. The paper proposes a set of simulations and measurements aiming to determine the attenuation of the GSM and Wi-Fi signals as they pass through different types of construction materials. Using MATLAB SimulinkÂ© and experimental studies using different scenarios, it was concluded that a combination of materials may be used to restrict the area of influence of the Wi-Fi signal, without affecting the GSM signal. Key words: attenuation, GSM, Wi-Fi.
