Crowd sensing using radio frequency sensing from multiple wireless nodes
Techniques are provided for obtaining environmental information using radio frequency sensing by one or more wireless devices. An example method of crowd sensing and/or environmental detection using radio frequency sensing with one or more wireless devices includes providing radio frequency sensing assistance data to one or more wireless devices, receiving radio frequency sensing reports from the one or more wireless devices, determining one or more environmental characteristics based on the radio frequency sensing reports. Environmental characteristics can include a location or movement of one or more target objects, or attributes of one or more target objects (e.g., one or many people, vehicles, animals, drones or other target objects), or any combinations thereof. This may assist with monitoring of a crowd or road traffic and/or with identifying and tracking a particular person or vehicle.
