Abstract: Methods, systems, computer-readable media, and apparatuses for using a small cell as a reliable crowd-sourcing agent are presented. In some embodiments, a small cell installed at a known location may observe one or more wireless signals at the known location, wherein the small cell comprises a built-in network listen receiver for observing cellular downlink signals. Subsequently, the small cell may provide, to at least one crowdsourcing 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 at least one crowdsourcing server is a Positioning Reference Signal (PRS) configuration based on an observed LTE downlink signals. In at least one arrangement, the information provided to at least one crowdsourcing server is configured to be used by the at least one crowdsourcing server in providing position assistance information.
