Fixed infrastructure devices (FIDs) may be configured to work with other devices (e.g., other FIDs, mobile wireless devices, etc.) to obtain or improve location information and/or provide enhanced location based services (e.g., emergency location service, commercial location service, internal location service, lawful intercept location service, etc.) to other devices or programs. For example, a first fixed wireless device may be configured to receive information that was obtained via a geospatial system, and determine whether it is able to establish a location fix based on this information. In response to determining that it is unable to establish a location fix based on the received information, the device may establish a communication group and/or collect additional location information from devices that belong to the communication group. The device may use this information to compute a new three-dimensional location fix, and use this new fix to provide the location based service.
