Abstract: Systems and methods for using radio frequency signals and sensors to monitor environments (e.g., indoor building and adjacent outdoor 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 determine localization of the plurality of sensor nodes within the wireless asymmetric network, to monitor loading zones and adjacent regions within a building based on receiving information from at least two sensor nodes, and to determine for each loading zone whether a vehicle currently occupies the loading zone.

Abstract: Systems and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, a method comprises initiating calibration, with processing logic, of at least one component of RF circuitry having a transmit chain and a receive chain of a first wireless node by generating a first loopback calibration signal and passing this first loopback calibration signal through the transmit chain and the receive chain of the first wireless node. The method further includes measuring a first transmit time delay for passing the first loopback calibration signal through the transmit chain and also measuring a first receive time delay for passing the first loopback calibration signal through the receive chain of the first wireless node.

Abstract: Systems and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, an asynchronous system includes a first wireless node having a wireless device with one or more processing units and RF circuitry for transmitting and receiving communications in the wireless network architecture including a first RF signal having a first packet. The system also includes a second wireless node having a wireless device with a transmitter and a receiver to enable bi-directional communications with the first wireless node in the wireless network architecture including a second RF signal with a second packet. The first wireless node determines a time of flight estimate for localization based on a time estimate of round trip time of the first and second packets and a time estimate that is based on channel sense information of the first and second wireless nodes.

Abstract: Systems and methods for implementing power management features while providing a wireless asymmetric network are disclosed herein. In one embodiment, a system includes a hub having a wireless control device that is configured to control communications and power consumption in the wireless asymmetric network architecture and sensor nodes each having at least one sensor and a wireless device with a transmitter and a receiver to enable bi-directional communications with the wireless control device of the hub. The wireless control device is configured to determine a scheduled timing of operating each sensor node during a first time period that is close in time with respect to a transmit window of the transmitter and during a second time period that is close in time with respect to a receive window of the receiver for each wireless device to reduce power consumption of the wireless devices of the sensor nodes.

In one example, a system for localization of nodes in a wireless network architecture comprises a plurality of wireless anchor nodes each having a known location and a wireless device with one or more processing units and RF circuitry for transmitting and receiving communications in the wireless network architecture and a wireless node having a wireless device with a transmitter and a receiver to enable bi-directional communications with the plurality of wireless anchor nodes in the wireless network architecture. One or more processing units of at least one of the plurality of wireless anchor nodes are configured to execute instructions to determine a set of possible ranges between each anchor node and the wireless node having an unknown location and to perform a triangulation algorithm that iterates through possible locations of the wireless node to minimize error.
