In some implementations, a first device may obtain first channel state information (CSI) of a second device. The first device may determine that a variance of the first CSI exceeds a variance threshold. The first device may determine that a motion event has occurred based on determining that the variance, of the first CSI, exceeds the variance threshold. The first device may determine a location of the motion event based on the first CSI and second CSI of a third device. The first device may adjust an operation of one or more devices associated with the location based on determining the motion event.

Systems and methods for detecting motion events based on channel state information

A device may receive radio frequency (RF) transmissions from access points provided in a zone, and may calculate channel state information (CSI) for the access points based on the RF transmissions. The device may identify CSI phases that satisfy a phase threshold to eliminate surrounding movement in the zone and to focus on an entry location of the zone, and may perform a short-time Fourier transform of the CSI phases to generate a frequency versus time graph. The device may perform a spectrogram analysis of the frequency versus time graph or may process the frequency versus time graph, with a machine learning model, to determine a quantity of people in the zone and a start and stop times associated with entries and exits of the people to and from the zone. The device may perform actions based on the quantity of people and the start and stop times.

Systems and methods for detecting motion in a zone

One or more computing devices, systems, and/or methods for calibrating barometric sensors and/or determining altitudes of devices are provided. In an example, a device is determined to be outdoors. In response to determining that the device is outdoors, a calibration process associated with a barometric sensor of the device is performed. The calibration process includes performing one or more barometric measurements using the barometric sensor to determine one or more barometric pressure measures, determining one or more locations of the device, wherein the one or more locations are associated with the one or more barometric measurements, and determining a barometric offset based upon the one or more barometric pressure measures and one or more reference values. An adjusted barometric pressure and/or an altitude of the device is determined based upon a first barometric pressure measure and the barometric offset.

Barometric sensor calibration and altitude determination

A method, a device, and a non-transitory storage medium are described in which an inter-networked content service is provided. The inter-networked content service may allow an end device to receive content from a set top box when the end device is not connected to a local area network of the set top box. The inter-networked content service may provide for push notification messaging between the end device and the set top box to obtain network address, status, and port information in support of a content session.

Content delivery to over the top device from customer premises equipment using notifications and dynamic port assignment

A first device may discover, using a short-range wireless communication protocol, an authentication service advertised by a second device, and may establish, with the second device, a connection using the short-range wireless communication protocol. The first device may display, after establishing the connection with the second device, a first identifier, and may provide to the second device a confirmation request including the first identifier to permit the second device to determine whether a second identifier, input by a user into the second device, matches the first identifier. The first device may receive, from the second device, encrypted credentials to authenticate the user to access a service based on the second device determining whether the second identifier matches the first identifier. The first device may decrypt the encrypted credentials to obtain credentials, and may authenticate, using the credentials, the user to access the service.
