The much anticipated (by me) war driving mode has been added to RF Signal Tracker. I have wanted to do something in the Wi-Fi area for some time now. It only made sense to add this to the engineering app (which already collects signal data). The trick was conceptual -- how to display hotspots which do not have a LAT/LON associated with them? I finally came to the (brilliant?) conclusion that I should just show the mobile's location and the strongest signal for that hotspot. This way I can show multiple Wi-Fi hotspots in a semi-orderly manner -- walking around an apartment complex will reveal numerous hotspots literally occupying the same latitude and longitude. I also added a way of filtering the list of collected hotspots by their security setting (in case you want to find an open one).
