Abstract: Method, apparatus and systems for detecting motion of an object based on a received wireless signal include comparing a received wireless signal to an adaptive noise immunity threshold, if the received wireless signal satisfies the adaptive noise immunity threshold. The detecting motion is based at least in part on a comparison between a determined multipath amount of the received wireless signal and a reference multipath amount, and further by adjusting the adaptive noise immunity threshold from a first level to a second level prior to the comparing of the received wireless signal to the noise immunity threshold, where the second level is higher than the first level.

Abstract: This disclosure includes systems and methods for determining the location of each of a plurality of STAs of a WLAN where an AP measures the round-trip time (RTT) and the angle of arrival (AOA) to each STA from implicit packet exchange, such as data frame and ACK frame. The AP may then report the RTT and AOA measurements to each STA using a dedicated beacon information element (IE) which multicasts RTT and AOA measurements to the STAs. By employing an additional parameter, namely, angle of arrival AOA, a single AP may compute the two-dimensional location of each associated STA. Further, another beacon IE may multicast mapping of the AIDs to MAC addresses so that the associated STAs can understand such mapping for STAs in a network so that one STA may know the location of other STAs. Encryption may be employed to achieve privacy.
Abstract translation: 本公开包括用于确定WLAN的多个STA中的每一个的位置的系统和方法，其中AP从隐式分组交换测量到每个STA的往返时间（RTT）和到达角（AOA），例如 数据帧和ACK帧。 然后，AP可以使用将RTT和AOA测量多播到STA的专用信标信息元素（IE）向每个STA报告RTT和AOA测量。 通过采用附加参数，即到达角AOA，单个AP可以计算每个相关STA的二维位置。 此外，另一个信标IE可以将AID多播到MAC地址，使得相关联的STA可以理解网络中的STA的这种映射，使得一个STA可以知道其他STA的位置。 可以采用加密来实现隐私。

Abstract: A method and apparatus for broadcasting short interframe space information to aid in determining a round trip time are provided. The round trip time is used as an aid in locating nodes within a WiFi or WLAN network. The method begins with capturing a time of transmission of a frame by a transmitting station. The receiving station then captures the time of arrival of the frame just sent by the transmitting station. The receiving station replies with a received frame message and the time of departure is captured. The transmitting station then captures the time of arrival of the received frame message. The captured arrival and departure times of the frame and the received frame message allow the round trip time to be computed. The RTT may then be included as part of a network message.

Abstract: A TOA positioning system can be implemented that employs a calculated initial location of a wireless network device. For each of a plurality of reference wireless network devices, a distance between the wireless network device and the reference wireless network device is determined based, at least in part, on a round trip transit time between the wireless network device and the reference wireless network device. An initial location of the wireless network device can be calculated based, at least in part, on a location of each of the plurality of reference wireless network devices. A location of the wireless network device can be estimated based, at least in part, on the calculated initial location, the distance to each of the reference wireless network devices, and an initial distance calibration constant.

Abstract: Embodiments described herein address these and other issues by providing radio frequency (RF) sensing to determine the status of a driver or other occupant of the vehicle. RF sensing may be provided by existing radios of a vehicle, such a Wi-Fi transceiver, and may therefore provide RF sensing functionality to a vehicle with little added cost. RF sensing can be leveraged to implement safety features such as detecting an unattended child or pet in a vehicle, detecting driver alertness, and the like.
