Abstract (en)
[origin: WO2020172014A1] Systems and apparatuses for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, an asynchronous system includes first and second wireless nodes each having a wireless device with one or more processing units and RF circuitry for transmitting and receiving communications in the wireless network architecture. The system also includes a third wireless node having an unknown location and a wireless device with a transmitter and a receiver to enable communications with the first and second wireless nodes in the wireless network architecture. The one or more processing units of the first wireless node are configured to transmit instructions to a cloud based entity or execute instructions to determine a location coordinate hypothesis and a transmit time hypothesis for a transmitted communication of the third wireless node, determine an error function associated with the transmit time hypothesis for each received path j of the receiving first and second wireless nodes at the location coordinate hypothesis, and determine a probability function of the error function for each received path j of the first and second wireless nodes using statistical properties of path measurement accuracy.
