Methods, systems, computer-readable media, and apparatuses for using a smart meter as a reliable crowd-sourcing agent are presented. In some embodiments, a smart meter installed at a location may observe one or more wireless signals at the location. Subsequently, the smart meter may provide, to at least one signal almanac server, information that identifies the location and describes one or more detected properties of the one or more observed wireless signals. In at least one arrangement, the information provided to the at least one signal almanac server may be configured to be used by the at least one signal almanac server in providing position assistance information to one or more mobile devices located in a vicinity of the location.
