Wireless signal-strength data from the USC SAL200 building. Four 802.11b devices were placed in the environment to act as beacons, and two robots were used to gather signal strength values. The robots were localized using laser-based MCL to provided "ground truth" pose esimates. See [Howard, FSR03] for an experimental study of WiFi signal-strength-based localization.
