Abstract
A method for determining a geospatial location of a client in signal communication with a wireless array is provided. A magnetometer is used to provide geospatial orientation information relating to an orientation of a wireless array relative to the surface of the Earth. The geospatial orientation of the wireless array is determined based on the geospatial orientation information provided by the magnetometer. A transceiver in the wireless array that the client is in signal communication with is identified. The geospatial orientation of the transceiver that the client is in signal communication with is identified based on the geospatial orientation of the wireless array and the position of the transceiver in the wireless array. A geospatial direction of the client relative to the wireless array is calculated based on the geospatial orientation of the transceiver the client is in signal communication with and is used to identify a geospatial sector in which the client is located.
