Abstract
A WLAN positioning system for calculating the geographic location of a mobile device minimizes the amount of data retrieved from a remote access point location server by dynamically switching between public fetching operations and private fetching operations in response to one or more parameters including, for example, whether the mobile device is in motion, the data retrieval history of the mobile device, and/or the capacity and utilization of local memory provided within the mobile device.
