摘要： Improvements associated with determining a location of a station device are described. According to one improvement, a method is performed by a network device. The method includes receiving a response packet from a station device, multiple times, as received signals by switching between a plurality of antennas of the network device during reception of each occurrence of the response packet. The received signals are converted to corrupted orthogonal samples. The response packet is received from the station device a final time as a final response packet via a single antenna of the plurality of antennas. Ideal orthogonal samples are re-generated based at least in part on the final response packet. Signal phase information, embedded in the corrupted and ideal orthogonal samples, is converted into estimated locations of the station device.

摘要： Embodiments of systems and methods for geo-location of a computing resource are generally described herein. In some embodiments, a first computing device determines a geographical location of the first device. The first device accesses an identifier of a second computing device and associates the location with the second device. The first device transmits a notification of the location being associated with the second device to the second device. In response to receiving the notification, the second device periodically transmits a message to the first device. The second device may detect a disconnection of a wired connection coupling the second device with an external system. In response to the detection, the second device ceases the periodic transmission of the message. The first device dissociates the location from the second device based on an elapsed time period since reception of a most recent one of the messages exceeding a predetermined time period.

摘要： A method and system for reading RFID tags in a high-density environment using a directional scanning antenna system is provided. The directional scanning antenna system consists of transmit and receive antennas having highly directional antenna patterns which work together to read and locate the tags. In operation both types of antennas are stepped in a circular fashion with respect to each other wherein the transmit antenna's antenna pattern pauses during rotation while the receive antenna pattern sweeps across the radiating antenna's path produced by the transmit antenna such that the antenna patterns produced from each isolate and determine the location of the tags.
