Abstract
The present disclosure discloses a method and network device for detecting movement in a physical environment. Specifically, a network device obtains a first feedback information for a first set of wireless signals transmitted by a first device in a physical environment and received by a second device in the physical environment. Moreover, the network device obtains a second feedback information for a second set of wireless signals transmitted by the first device and received by the second device. The network device then compares the first feedback information to the second feedback information to identify a first set of one or more difference values. Based on the first set of one or more difference values, the network device determines that one or more physical entities within the physical environment have moved.
