Abstract
A method and system of adjusting a radio frequency (RF) broadcast signal power level in a crowd-sourced mobile device localization system in a pedestrian area. The method is executed in the processor of a server computing device and comprises localizing a first and at least a second mobile devices to establish respective first and at least second estimated positions within the pedestrian area in accordance with fingerprint data of the pedestrian area, the first and the at least a second mobile devices broadcasting a respective localization data packet that includes the respective first and at least a second estimated positions at a first and an at least a second broadcast power levels respectively, determining a respective confidence level indicative of a degree of accuracy for the first and the at least a second estimated positions, and when the respective confidence level for at least one of the first estimated position and the at least a second estimated position is one of above and below a threshold confidence level, perform at least one of lowering and increasing at least one of the first broadcast power level and the at least a second broadcast power level.
