Abstract
Systems and methods for using radio frequency signals and sensors to monitor environments (e.g., indoor environments) are disclosed herein. In one embodiment, a system for providing a wireless asymmetric network comprises a hub having one or more processing units and at least one antenna for transmitting and receiving radio frequency (RF) communications in the wireless asymmetric network and a plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional RF communications with the hub in the wireless asymmetric network. The one or more processing units of the hub are configured to execute instructions to determine at least one of motion and occupancy within the wireless asymmetric network based on a power level of the RF communications.
