This talk relates our experiences in 2.4 GHz wireless AP mapping, giving a broad sweep through various motivations, implementations, analyses, and applications. This includes practical description of software, hardware, antennae, and other devices that we have found useful to interact with and measure wireless devices. We employ a very hands-on philosophy in our work and the talk. Given the current explosion in wireless deployment, formal research in this area has come to be important. This talk will attempt to illustrate some of our directions.
