Abstract
A method and apparatus for harvesting information from a plurality of radio frequency (RF) sources. In one example, a collector device receives RF signals from the RF sources to produce the harvesting information. The collector device also determines environmental context information describing a physical environment of the collector device as the RF signals were being received, and a position of the collector device where the RF signals where received. The collector device then associates the environmental context information with the harvesting information and the position, and transmits the harvesting information and position with the associated environmental context information to a server device. The server device may then compute positioning information biased to different environmental contexts. This biased positioning information may then be utilized by other collector devices having similar environmental contexts to better estimate their respective locations.
