Abstract
A cellular wireless communications system and method of generating reference signatures for use in geolocation are provided. The cellular wireless communications system identifies a sub-area within the coverage area of a cellular wireless communications system, the sub-area having a density of radio frequency measurements that is below a threshold value. A user of a subscriber mobile communication unit is influenced to enter the sub-area, the subscriber mobile communication unit being a subscriber to the cellular wireless communications system. The cellular wireless communications system obtains radio frequency measurements from the subscriber mobile communication unit in the sub-area, and generates reference signatures and/or location estimates from the radio frequency measurements. The reference signatures may be used to geolocate connections made by other mobile communication units within the sub-areas.
