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 one or more processing units of the first wireless node are configured to execute instructions to determine a coarse time of flight estimate of the first and second packets and a fine time estimate of the time of flight using channel information of the first and second wireless nodes.

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.
