Abstract
A system and method for determine the spatial position of a network device is disclosed. A locator device having an antenna array is used to perform an AoX calculation to find the direction to the network device. The AoX calculation utilizes a plurality of the antennas in the antenna array. The locator device also performs a high accuracy distance measurement (HADM). In certain embodiments, only one antenna in the antenna array is used for the HADM calculation. Using the direction and the distance to the network device, the locator is able to determine the spatial position of the network device. In some embodiments, the antenna array may a rotational symmetry array having a plurality of outer antenna elements and one central antenna element.
