    Abstract: A system for location based security which includes a plurality of receivers. Each of the receivers determines times of arrival of received time varying signals. The system also includes a server in communication with the receivers and a mobile device. The server receives the times of arrival from the receivers, and times of arrival of the time varying signals determined by the mobile device. The server determines a location of the mobile device based on the times of arrival. The server may then authorize the mobile device to perform secure communication over the secure communication network when the location of the mobile device is determined to be in an authorized communication area defined based on the times of arrival received from the receivers.

    Abstract: A method and apparatus for harvesting information from a plurality of radio frequency (RF) sources. In one example, a collector device receives RF signals from the RF sources to produce the harvesting information. The collector device also determines environmental context information describing a physical environment of the collector device as the RF signals were being received, and a position of the collector device where the RF signals where received. The collector device then associates the environmental context information with the harvesting information and the position, and transmits the harvesting information and position with the associated environmental context information to a server device. The server device may then compute positioning information biased to different environmental contexts. This biased positioning information may then be utilized by other collector devices having similar environmental contexts to better estimate their respective locations.

    Abstract: A method for tracking collector devices in an indoor area associated with imaging devices and RF signal sources covering the area includes generating aspects of a plurality of coarse position tracks of the collector devices based on RF signal measurements obtained by the collector devices from the RF signal sources. Imaging devices capture image frames of the collector devices in the indoor area which are then processed in order to determine aspects of a plurality of fine position tracks of the collector devices. The server and the collector device communicate with each other and match aspects of at least one of the fine position tracks to the aspects of the coarse position track of the communicating collector device in order to determine the precise location of the collector device in the indoor area.
