    摘要： Multiple methods for determining a location of a STA operating on a mesh wireless network are described herein. A STA finder is used to monitor changes in received signal strength at each access point of a group of access points operating the mesh wireless network. The changes in received signal strength are then utilized to determine a location of STAs operating on the mesh wireless network. Methods for identifying poor performance areas on the mesh wireless network using the position information and then providing recommendations for improving the performance of the mesh wireless network are also described herein.

    摘要： A system and method for ranging secured by feedback of one or more channel metrics. The method may include: receiving, by a first modem, a first training signal, from a second modem; generating, by the first modem, a first estimate of a channel metric, based on the first training signal; receiving, by the first modem, from the second modem, a second estimate of the channel metric; determining, by the first modem, that the first estimate of the channel metric and the second estimate of the channel metric do not meet a similarity criterion; and denying, by the first modem, access to a resource.

    摘要： An information output method includes: obtaining travel information relating to travel of a mobile object capable of autonomously traveling and being subjected to at least one of remote operation or remote monitoring; obtaining location information relating to a remoting-required location where at least one of remote operation or remote monitoring is required; determining whether mobile objects will be located in one or more remoting-required locations at the same timing, based on the travel information and the location information; generating control information for controlling at least one mobile object, among the mobile objects, to prevent the mobile objects from being located in the one or more remoting-required locations at the same timing, when the mobile objects are determined to be located in the one or more remoting-required locations at the same timing; and outputting the control information.

    摘要： A method for activating a vehicle function, by an activation device including a transceiver to communicate with “hands-free” access equipment. The transceiver is equipped with a gyroscope and a magnetometer and two receiving antennas that have a coefficient of electromagnetic coupling between them that is below a threshold. The method includes the following steps for at least two consecutive footsteps: transmission of a signal comprising data of the gyroscope and the magnetometer of the “hands-free” equipment to the vehicle; comparison of the data with representative values of the gyroscope and the magnetometer of the transceiver; determination of a first direction of the user; determination of a second direction of the user based on an estimation of a first angle of arrival of the signal towards the transceiver; comparison of the first direction and the second direction; activation of the vehicle function on the basis of the result of the comparison.

    摘要： A disclosed method includes receiving a time-of-arrival range filter configuration and a reference signal physical transmission time from a network node at a reference signal physical reception time. The time-of-arrival range filter configuration includes at least one of a time-of-arrival filter status, a time-of-arrival filter distance range, and a time-of-arrival configuration. A time difference between the reference signal physical reception time and the reference signal physical transmission time is determined, and a distance to the network node based on the time difference is calculated. Whether the distance is within the time-of-arrival filter distance range is determined, and the time-of-arrival filter status is determined. Based on the time-of-arrival filter status, actions are performed in accordance with the time-of-arrival configuration applicable for the distance.

    摘要： An apparatus or an add-on module for a, in particular mobile, device, is disclosed. In an embodiment, the device to be localized or the add-on module uses a measuring unit to measure, via suitable sensors, a local electromagnetic field distribution generated by a given infrastructure. An instantaneous position of the add-on module or of the device equipped therewith is then determined by comparing the measured field distribution with a specified map. In order to facilitate tracking of the add-on module or of the device, the measured field distribution and/or the determined position can be sent via a wireless data connection to a server unit.

    摘要： A receiver includes a first discrete Fourier transform (DFT) block to perform a first single tone DFT on a positive tone associated with a sounding sequence. A second DFT block performs a second single tone DFT on a negative tone associated with the sounding sequence. A DFT coefficient generation block generates first DFT coefficients based on a nominal frequency of the positive tone and an estimated frequency offset between a transmitter frequency and a receiver frequency. The DFT coefficient generation block generates second DFT coefficients based on a nominal frequency of the negative tone and the estimated frequency offset. Multipliers in the DFT blocks multiply I and Q values of the sounding sequence with the coefficients. Accumulators in the DFT blocks accumulate multiplier outputs. An arctan function receives averaged accumulated values from the first and second DFT blocks and supplies first and second phase values used to calculate fractional timing.
