Determining a location of a mobile user terminal

An apparatus determines whether a first mobile user terminal and a second mobile user terminal are within a relative geographic proximity of one another, in dependence on a property of intermediate network equipment of a packet-switched network to which the first and second mobile user terminals are operable to connect. The apparatus also obtains a geographic location of the second mobile user terminal and, when the first and second user terminals are within the proximity, uses the geographic location of the second mobile user terminal in estimating a geographic location of the first mobile user terminal. Proximity can be determined based on whether the terminals are connected to the same sub-network or share the same address space or connect to the same network interface address, a threshold number of hops, , transmit time or round trip time of packets or type of access technology available. Proximity may further depend on a shared authentication element such as a cryptographic key.

Locating devices based on antenna coordinates

A technique for locating devices detects wireless packets using multiple antenna units and generates antenna coordinates in an antenna coordinate system on a per-packet basis. Information about antenna coordinates are stored in entries of a data store. Packets originating from different locations produce different antenna coordinates, enabling antenna coordinates to differentiate regions in physical space. Although antenna coordinates do not directly describe physical locations, they are stable over time given a stable environment and thus allow determination as to whether a location has been visited before. Entries in the data store may store Cartesian (physical) coordinates associated with respective antenna coordinates, enabling real-time tracking of physical device locations by lookups into the data store based on antenna coordinates.
