The map I have created was based off of a Google Earth satelite screen shot of the "Lone Mountain" building on the University of San Francisco campus. I selected that particular area partially because it is close to my home, and I am a tranfer student and attended USF last year.

It is not apparent from the screen shot, but the middle bottom (where most of the blue and green clusters are) there is a staircase going up to the main building of roughly 200 brutal stairs. I also found it somewhat amusing watching students juggling a cell phone, a cigarette, a soda, all while hiking up the mountain (literally). As a result, most students stop in convenient areas (benches, fountains, basically any seating) to catch their breath and finish their phone conversation. Thus came forth the basis for my investigation- which of these areas have service, and which dead zones should be avoided? I then decided to include alternate routes for those like myself who will do anything to avoid the stairs, including the "back way" for students entering on Anza Street rather than Turk.

I did not mark each level of service recieved on my cell phone, and opted only to show the low service (between 1 and 2 bars) and dead zones (no bars). I had made a previous map with every level of bars on it, but I do not think students will change their location when it is toggling between 4 and 5 bars- what's the difference, as long as the voice on the other end is audible? With the marking of dead zones, it will be easier to avoid them, instead of basing your phone conversation on your every step (.. can you hear me now?)

I also later noted that the change in altitude could have had an effect on my results, as it appears that service decreases as the altitude increases (Turk St has an elevation of 348 ft, the main Lone Mountain building has an elevation of 406 ft).
