SYSTEMS AND METHODS FOR PRECISE RADIO FREQUENCY LOCALIZATION USING TIME DIFFERENCE OF ARRIVAL

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 eachhaving 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. 本文公开了用于确定网络架构中的无线节点的位置的系统和装置。在一个示例中，异步系统包括第一无线节点和第二无线节点，每个无线节点具有带有一个或多个处理单元的无线装置以及用于在无线网络架构中发送和接收通信的RF电路。系统还包括无线节点，该无线节点具有未知位置和
