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.
