Abstract
Embodiments described herein provide improvements to the accuracy of location estimates. In one embodiment, an apparatus stores a first plurality of RF signal strength values that are mapped to known locations, and stores a second plurality of RF signal strength values that are not mapped to known locations. The apparatus estimates locations where the second plurality of RF signal strength values was measured based on the first plurality of RF signal strength values and their corresponding known locations, calculates an uncertainty for the estimated locations, and identifies an estimated location having a highest uncertainty. The apparatus directs a measurement device to measure an RF signal strength value at a known location that corresponds with the estimated location, and adds the RF signal strength value to the first plurality of RF signal strength values to reduce an uncertainty in subsequent estimates of locations within the broadcast area.
