This experiment was designed to see how different materials interfere or block out cell phone signal. Two cell phones were used (one to call the other). Both cell phones used the same service company.
Cell 1 was the phone wrapped in material or put into different places. It did not matter that the signal wasn't full bar because the point of the experiment was to see how the materials affect the reception. The reception of Cell 2, however, did matter. Every time a test was done, it was always made sure that the signal bar was full.
The experiments took place when the weather was clear (minimal clouds, rain, fog etc) so that the weather wouldn't interfere too much with the tests. The tests were repeated three times to get a better result. The average was then calculated. The time was determined from the) time the call button (on Cell 2) was pressed to the time the first ring was heard(on cell 2). This helped determine how well or how bad the signal was.
The first test was when Cell 2 called Cell 1 without anything covering it. The times were 5.56s, 6.91s and 5.18s with the average being 5.88s. The second test was the plastic cling wrap around Cell 1. …show more content…
Out of the tests where the call went through, the test with Cell 1 in the fridge took longer than the other materials/places. This could be due to the fact that fridges also contain metal in them. This, again, proves that metal interferes with reception. Both the tests with the phone in the car and in the garage were just under 7 seconds. The test with the phone in the car took about 6.85 seconds because the outer layer of the car is made of metal, but the windows allow reception through. The test with the phone in the garages was about 6.94 seconds because the garage is a very isolated area. The building materials do allow reception in, but it may also interfere with the amount of signal going through the
