Method and system for server based mobile device monitoring in crowd-sourced pedestrian localization

Abstract

Methods and Systems of adjusting a radio frequency (RF) broadcast signal power level in a crowd-sourced mobile device localization system in a pedestrian area are described. In an example, a first mobile device and a second mobile device may be localized to establish a first estimated position a second estimated position, respectively. The localizing may be based on fingerprint data of the pedestrian area, wherein a localization data packet including the first estimated position broadcasted by the first mobile device at a first broadcast power level and another localization data packet including the second estimated position broadcasted by the second broadcast device at a second broadcast power level may be received. Based on a degree of accuracy of the first estimated position and/or the second estimated position, an input may be provided to increase and/or lower at least one of the first broadcast power level and the second broadcast power level, wherein broadcast power levels mobile devices are increased and lowered based on a power level budget for the crowd-sourced localization system.
