#### Abstract

In this project, there were multiple objects put over a certain WiFi router at Heathwood Hall Episcopal School to test which objects had the most negative effect on WiFi strength. Those objects used were, a cardboard box, cling wrap, a water bottle with water in it, an aluminum pan, and a human body. The technique used to gather the data involved measuring WiFi router signal strength with a computer, while standing off to the side so that the person’s body did not affect the WiFi strength. For this study the independent variable was the objects that covered the WiFi router. The dependent variable was the strength of the WiFi signal. The hypothesis was, if the cardboard box was placed over the WiFi router, then the WiFi strength would decrease the most. The null hypothesis was if the cardboard box was placed over the WiFi router, then the WiFi strength wouldn’t change. The results suggest that the cling wrap had the most negative effect and the cardboard box had the least negative effect. Another big factor on the WiFi strength was the human body. When this project was first run, the person holding the objects up to the WiFi router was in the way, and this very likely caused the results of percentages in the low 40s and the normal percentage in the 60s.

In this project, there were multiple objects put over a certain WiFi router at Heathwood Hall Episcopal School to test which objects had the most negative effect on WiFi strength. Those objects used were, a cardboard box, cling wrap, a water bottle with water in it, an aluminum pan, and a human body. The technique used to gather the data involved measuring WiFi router signal strength with a computer, while standing off to the side so that the person’s body did not affect the WiFi strength. For this study the independent variable was the objects that covered the WiFi router. The dependent variable was the strength of the WiFi signal. The hypothesis was, if the cardboard box was placed over the WiFi router, then the WiFi strength would decrease the most. The null hypothesis was if the cardboard box was placed over the WiFi router, then the WiFi strength wouldn’t change. The results suggest that the cling wrap had the most negative effect and the cardboard box had the least negative effect. Another big factor on the WiFi strength was the human body.
