Dead Zone

Overview

Objectives/Goals My project explores what substances affect cell phone signals the most. It also considers which cell phone carriers can resist different substances better than others Methods/Materials The first thing that I did was get all the substances that I was going to test and three different phones, each with a different carriers: Verizon, T-mobile, and AT&T. I bought bricks, drywall, plywood, and solid wood. I made a miniature house out of all of these substances and put all three cell phones inside them one at a time. After I finished testing everything, I got all three cell phones and put them extremely close to a microwave to test electrical interference. I recorded all of these things in my notebook and then added them into Microsoft Excel to make a table. Results In the findings of this experiment, the substances that affected Verizon#s bars the most were bricks. For AT&T it was the electricity that affected the number of bars the most. The substance that affected the reception the most for T-mobile was also electricity. Conclusions/Discussion In conclusion, the substances that affected the signals most were the bricks, and electricity. This was the case for all three carriers that I tested#Verizon, T-mobile, and AT&T. Drywall caused the next level of interference. Following that, came the solid wood and plywood. In general, AT&T had the strongest reception with all of the barriers.
