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 wireless node having an unknown location and a wireless device with a transmitter and a receiver to enable communications with the first and second third wireless nodes in the wireless network architecture. The first wireless node transmits a communication to the second wireless node and the wireless node having an unknown location, receives a communication with an acknowledge packet from the wireless node, and determines time difference of arrival information between the first and second wireless nodes.
