I have way too much time to spare, so I came up with this fun little project. What i want to do is use my phone or laptop to incrementally collect data on WiFi strength at my location at that time, using GPS (longitude and latitude), and once I have enough data, (I'm fine if it takes like several months, I'm still in high school, and I'll be walking around in classrooms anyways.) I'll plot all the data in Mathematica so that there's a somewhat continuous graph of WiFi strength throughout the entire school. My question is this: what sorts of things should I learn in order to make this process more automated/simple. I'm open learning new languages or learning how to make Android apps. Currently, I only know how to program in Mathematica. Perhaps I could make an android app that runs in the background and have as many friends download it as possible?
