Claim:
1. A small cell-based method for crowdsourcing wireless signals comprising: observing, by a small cell installed at a known location, one or more wireless signals at the known location within an operating environment comprising signals from the small cell and one or more non-small cell sources, wherein the one or more wireless signals observed by the small cell comprise signals from the one or more non-small cell sources, wherein the one or more non-small cell sources comprise at least one Long Term Evolution (LTE) cell, wherein the small cell comprises a built-in network listen receiver for observing cellular downlink signals; and providing, by the small cell, to at least one crowdsourcing server, information that (1) identifies the known location, (2) describes one or more detected properties of the one or more observed wireless signals from the one or more non-small cell sources, wherein the one or more detected properties comprise an indication of a Positioning Reference Signal (PRS) sequence transmitted by the at least one LTE cell, and (3) identifies the small cell as a sender of the information, wherein the at least one crowdsourcing server determines a reliability ranking for the information.
