摘要： Embodiments of the invention include a method for creating probe requests. The method is used when positioning is required. A short probe request is constructed with SSID set to GPS SSID_NAME. Another method continues after a short probe response is received. It is determined if a SSID of the probe response matches the SSID of the short probe request. If it does send an ACK.

摘要： In the case of the process for secure access to a determined space, it is provided that after activation of the wearable object, a first coded signal is transmitted from the access or unlocking device, this first coded signal is received in the object and a coded response signal is transmitted with synchronisation to the device after a defined time of transmission. A processing of the coded response signal converted in the processing unit of the device is conducted in order to check the defined time delay and the response code of the wearable object and to determine the flight times of the signals between the device and the wearable object. The distance separating the wearable object and the access or unlocking device is thus calculated to authorise access to the determined space if the calculated distance is below a determined threshold after recognition of the wearable object.

摘要： Methods for determining a range rate of a backscatter transponder and readers implementing the methods are described. The reader transmits a continuous wave signal and receives a modulated reflected response signal from the transponder, mixes the modulated reflected response signal with the carrier frequency to produce a downconverted signal, bandpass filters the downconverted signal to pass a bandpass filtered signal containing at least the modulation frequency, applies a non-linear amplitude transfer function to produce a modulation-suppressed signal, and measures the frequency of the modulation-suppressed signal and determines the range rate from the measured frequency.

摘要： Systems, apparatuses, and methods estimate the distance between a player and a ball by transmitting a chirp (sweep signal) to a radio tag located on the ball. During the chirp, the frequency of the transmitted signal is changed in a predetermined fashion. The radio tag doubles the transmitted frequency and returns the processed signal to a transceiver typically located on the player. The currently transmitted frequency is then compared with the received frequency to obtain a difference frequency from which an apparatus may estimate the distance. The apparatus may simultaneously receive the processed signal from the radio tag while transmitting the sweep signal.

摘要： A measurement agent for measuring a distance from the agent to a tag may include a transmitter and receiver for transmitting and receiving radio wave signals. The agent is arranged for changing the agent transmitter from a particular state wherein the agent transmitter transmits a particular radio wave interrogation signal towards a further state determined by the agent wherein the agent transmitter transmits a further radio wave interrogation signal when a signal behavior of a received radio wave response signal changes. Further, the measurement agent includes a counter for determining a time period between transmittance of a first radio wave interrogation signal and receipt of a radio wave response signal having a predetermined signal behavior. The agent also includes a processor for computing a distance between the agent and the tag, based on the determined time period and a multiple number of radio wave interrogation signals.

摘要： An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.
