SYSTEMS AND METHODS FOR DETERMINING A TIMING OFFSET OF EMITTER ANTENNAS IN A WIRELESS NETWORK
Systems and methods for determining a timing offset of a plurality of emitter antennas in a wireless network. The methods include deploying a network synchronization calibration unit at a location within receiving range of a plurality of direct path reference signals transmitted by the plurality of emitter antennas. The synchronization calibration unit receives the plurality of direct path reference signals and one or more reflected reference signals, which are then separated from one another to identify the direct path reference signals when a signal strength of one direct path reference signal is less than a signal strength of a reflected reference signal. A set of data is collected from the reflected reference signals that is indicative of the timing offset and that set of data is analyzed to estimate the timing offset.
ANGLE OF ARRIVAL (AOA) POSITIONING METHOD AND SYSTEM FOR POSITIONAL FINDING AND TRACKING OBJECTS USING REDUCED ATTENUATION RF TECHNOLOGY
Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described.
