摘要： In a general aspect, a filter time aligns time varying RF-motion data. In some aspects, a method includes loading a first set of input signals (SISs) into an interference buffer over a first time period. The first SISs is based on a first set of wireless signals received by a wireless communication device (WCD) after being transmitted through a space. The method includes using the first SISs to determine an interference level. The method includes: in response to determining the interference level is below a threshold, executing a motion detection process in a second, subsequent time period over which a second SISs is loaded into the interference buffer. The motion detection process, using a subset of the first SISs, detects motion of an object in the space. The second SISs are based on a second set of wireless signals received by the WCD after being transmitted through the space.

摘要： In some aspects, a wireless-signal source locator system includes wireless sensor devices distributed at distinct locations over a geographic region. The wireless sensor devices are configured to passively monitor wireless communication network signals in the geographic region. Each wireless sensor device is configured to receive a source signal wirelessly transmitted by a source (e.g., a mobile device, etc.) and a reference signal (e.g., from a synchronization source). The wireless sensor devices can generate arrival-time data based on the source signal and the reference signal. The wireless-signal source locator system further includes a data analysis system configured to receive the arrival-time data from the wireless sensor devices and to identify a location of the source based on analyzing the arrival-time data generated by three or more of the wireless sensor devices.

摘要： In some aspects, a wireless-spectrum analysis technique includes obtaining, at a computer system, a simulated spatial distribution of a wireless signal parameter (e.g., spectral power). The simulated spatial distribution is based on a computer-simulation of wireless signal propagation in a geographic region. A measured spatial distribution of the wireless signal parameter is obtained at the computer system. The measured spatial distribution is based on measurements performed by wireless sensor devices in the geographic region. Each of the wireless sensor devices is configured to provide local parameter measurements based on wireless signals detected by the wireless sensor device. The simulated spatial distribution is compared with the measured spatial distribution. In some instances, the simulated spatial distribution geographic region is modified based on the comparison.

摘要： Systems and methods for time domain channel representation information for Wi-Fi sensing. Wi-Fi sensing systems include sensing devices and remote devices configured to communicate through radio-frequency signals. Initially, a sensing device receives a channel representation information configuration representative of channel state information in time domain. The sensing device then receives a sensing transmission and generates a sensing measurement based on the sensing transmission. Thereafter, the sensing device generates a time domain representation of the sensing measurement and selects one or more time domain pulses indicative of the time domain representation based on the channel representation information configuration. The sensing device communicates the one or more time domain pulses to a sensing algorithm manager for use in determining motion or movement.

摘要： A method includes receiving a ground-truth motion indication from a measurement device. The ground-truth motion indication is a time series of locations and a corresponding indication of a motion state at each location of the time series of locations. The method also includes receiving a time series of detected motion states based on wireless signals communicated through a space over a time period by a wireless communication network comprising a plurality of wireless communication devices. The detected motion states for a time interval within the time series are compared to the ground-truth motion indication for the time interval within the time series to generate a time series of consistency scores. The consistency scores are processed to produce an aggregate motion-detection capability score at each location. The method also includes providing, for display as a graphical representation of motion-detection capability within the space, the aggregate motion-detection capability at each location.

摘要： Systems and methods for accommodating flexibility in sensing transmissions are provided. Wi-Fi sensing systems include sensing devices and remote devices configured to communicate through radio-frequency signals.
