Abstract

Systems, apparatuses, and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, a 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. A second wireless node having a wireless device with a transmitter and a receiver enables 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 round trip time estimate of the first and second packets, to determine channel state information (CSI) of the first and second wireless nodes, and to calibrate hardware to determine hardware delays of the first and second wireless nodes.
