Claim Text:
1. A device, comprising: positioning logic configured to receive respective positions of a plurality of access points; and monitoring logic configured to classify a respective one of the plurality of access points as being mobile or fixed according to i) a hybrid position of the device determined independent of the respective one of the plurality of access points and ii) a recorded position of the respective one of the plurality of the access points, wherein the monitoring logic is configured to classify an access point as being mobile when a difference between the hybrid position of the device and the recorded position of the access point exceeds a threshold, wherein the monitoring logic is configured to determine the threshold according to a statistical distribution of a positioning error, and wherein an access point is classified as being fixed when the access point is located at a fixed position; wherein the positioning logic is further configured to determine a position of the device according to: i) channel powers of signals received from access points of the plurality of access points classified as being fixed and ii) fixed positions of the access points classified as being fixed, and wherein the positioning logic is configured to ignore positions of access points of the plurality of access points classified as being mobile when determining the position of the device.
