摘要： Methods, apparatus and systems for wireless motion monitoring to ensure security are described. In one example, a described system comprises: a transmitter configured for transmitting a first wireless signal through a wireless multipath channel of a venue; a receiver configured for receiving a second wireless signal through the wireless multipath channel; and a processor. The second wireless signal differs from the first wireless signal due to the wireless multipath channel and a motion of an object in the venue. The processor is configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal; computing a spatial-temporal information (STI) based on the TSCI; monitoring the motion of the object based on the TSCI and the STI; performing a task based on the monitoring; and generating a response based on the task.

The accessory comprises at least one physical attachment feature attaching the accessory to at least one of: a first wireless device in the wireless monitoring system or a second wireless device in the wireless monitoring system. The first wireless device is configured for transmitting a first wireless signal through a wireless multipath channel of a venue. The second wireless device is configured for receiving a second wireless signal through the wireless multipath channel. The second wireless signal differs from the first wireless signal due to the wireless multipath channel that is impacted by a motion of an object in the venue. The wireless monitoring system comprises a processor configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, and monitoring the motion of the object in the venue based on the TSCI.
