Abstract
A radio frequency signal mediator configured indoors passively receives signals from a user wireless device and determines layer two radio access network measurement data from the signals. At least one other radio frequency signal mediator in the same space also passively receives signals from the user wireless device and determines layer two radio access network measurement data from the signals. The radio frequency signal mediators send the data to a location determining device that determines a location for the user device based on the at least two sets of data and send the location data to a location server.
