1. A method for determining a location of a mobile device based upon weighted Received Signal Strength Indication (RSSI) and Round-Trip Time (RTT) data, the method comprising:
- determining an area in which the mobile device is located;
determining a condition of an environment of the mobile device based on location data associated with the area;
weighting, with a processing unit, RSSI and RTT data based on the condition of the environment; and
calculating the location of the mobile device based on the RSSI and RTT data with the determined weighting.

Abstract
The subject matter disclosed herein relates to utilizing location information, such as maps, in location determination based on Received Signal Strength Indication (RSSI) and Round-Trip Time (RTT) data. Weighting information can be determined from and/or provided in the location information. The weighting information associated with an area in which a mobile device is located can impact how RSSI and RTT data is weighted in a calculation of the mobile device'"'"'s location.
