    摘要： A system and method for locating a signal source are disclosed. The method utilizes signals S n received during respective time intervals {”t n } from the signal source by a number n of receivers {Rc n }, and data about the change {”R n } of the receivers' positions {R n }. The method includes processing the signals S n from each of the receivers to determine the phase ”¸ n accumulated in the signal S n during a respective time interval ”t n . Based on the determined accumulated phases {”¸ n }, the accumulated phases differences ””¸ mn (differential phase) between the signals, S m and S n , that are received by two or more pairs {m,n} of the receivers are determined. Then, the location of the signal source is determined such that it satisfies that the changes in the positions of the respective {n,m} receivers relative to that location correspond to the differential phases ””¸ nm between the signals received by the respective receivers.

    摘要： A wireless device detection computer device for determining the location of wireless device is provided. The WDD computer device includes a processor in communication with a memory. The processor is configured to receive a plurality of status messages from a plurality of anchor points. Each status message of the plurality of status messages includes a received signal strength associated with a first wireless signal received at the corresponding anchor point from a first wireless device. The processor is also configured to determine a plurality of subsets of the plurality of anchor points, determine a potential location of the first wireless device for each of the plurality of subsets, generate a clustering of the plurality of potential locations, select a first group of the plurality of subsets based on the clustering, and calculate a final location of the first wireless device.

    摘要： Embodiments of the invention address how trilateration processes, used to obtain a location of a mobile computing device, are affected by physical placement and sub-optimal selection of peer devices (PDs). Embodiments of the invention describe processes for selecting nearest PDs over further PDs, as received signal strength indicator (RSSI) measurements are more reliable—i.e., said “nearest PDs” provide more accurate distance measurements while improving the probability of finding more intersection points. Embodiments of the invention selectively utilize abnormal location poll data when executing location determination processes. Embodiments of the invention further enhance trilateration processes by utilizing dampening values for calculated location poll data.

    摘要： A method of selecting the positioning method(s) used to respond to given positioning requests uses historical performance data reflecting the actual performance yielded by one or more of the positioning methods that are generally available for selection. As a non-limiting example, a positioning node maintains or otherwise has access to historical data reflecting the QoS obtained for at least some of the positioning methods supported by the node. Correspondingly, the node compares the QoS requirements associated with an incoming positioning request to the historical performance data, to identify the positioning method(s) that appear to best satisfy the requirements. The positioning node therefore selects the “best” method(s) for responding to a positioning request, not based on “generic” performance characteristics of those methods, but rather based on observed real-world performance of those methods, as applicable to the particular operating environment (radio environment) in which the positioning methods are carried out.
