Abstract: The invention provides a novel method for preparing a wireless environment for location determination of a wireless mobile unit, and for location determination of a wireless mobile unit. In preparing the physical environment, the invention utilizes novel techniques, including novel techniques to place transmitters, the removal of outlying data in the creation of reference RF fingerprints, and algorithms to obtain accurate reference RF fingerprints. In determining the location of a wireless mobile unit, the invention utilizes novel techniques, including novel techniques to select transmitters, the removal of outlying data in the creation of reference RF fingerprints, and algorithms to obtain accurate reference RF fingerprints.

Abstract: A system is provided for delivery of services to at least one mobile device adapted to communicate in a wireless manner including a plurality of communication/detection devices. Each of the communication/detection devices is adapted to detect the presence of the mobile device when the mobile device is within the range thereof. Each communication/detection device is adapted to communicate information between the mobile device and the communication/detection device when the mobile device is within the range thereof. The system includes at least one multiplexer in communication with at least one of the communication/detection devices and at least one server including content stored thereon to provide at least one service to the client program on mobile device. The server is in communication with the multiplexer. The service to be provided to the mobile device depends on which one of the plurality of communication/detection devices is in communication with the mobile device.

Abstract: In one aspect, a software application for location determination of a mobile device connected to at least one network is provided. The software application comprises a first input to receive first location information indicative of a first possible location of the mobile device, the first location information obtained from a first source and determined based, at least in part, on signals exchanged over a first wireless connection of the at least one network, a second input to receive second location information indicative of a second possible location of the mobile device, the second location information obtained from a second source and determined based, at least in part, on signals exchanged over a second connection of the at least one network, and a location synthesizer coupled to the first input and the second input, the location synthesizer adapted to determine a synthesized location of the mobile device based, at least in part, on the first location information and the second location information.

Abstract: In on aspect, a dual mode radio frequency identification (RFID) tag adapted to facilitate location determination in a network is provided. The RFID tag comprises a transceiver adapted to wirelessly exchange information with the network, and a controller coupled to the transceiver, the controller configurable to operate the RFID tag in one of a plurality of modes, wherein, in a first mode of the plurality of modes, the controller is configured to transmit a chirp to the network via the transceiver to be used by at least one network component to determine a location of the RFID tag, and wherein, in a second mode of the plurality of modes, the controller is adapted to process information received from the network via the transceiver to compute a location of the RFID tag.

Abstract: A system for delivery of services to at least one client program on a mobile device adapted to communicate in a wireless manner including a plurality of communication/detection devices. Each of the communication/detection devices has a known range and is adapted to detect the presence of the mobile device when the mobile device is within the range thereof. Each communication/detection device is also adapted to communicate information between the mobile device and the communication/detection device when the mobile device is within the range thereof. The system further includes at least one multiplexer in communication with at least one of the communication/detection devices and at least one server including content stored thereon to provide at least one service to the client program on mobile device. The server is in communication with the multiplexer.

Abstract: In general, the present invention provides in one aspect thereof a device for proximity-based communication between the device and at least a second device.
