Abstract
Systems, methods, and devices are disclosed for enabling a mobile device with limited RF capability to obtain accurate directions for finding an object or asset via a multiple-antenna locator device. The mobile device generates a request to the locator device to obtain directions to find the asset. A request can also be made to obtain the mobile device's own location from the multiple-antenna locator device which has an antenna array and is in a fixed location that has good RF visibility. The locator device identifies the target asset and receives an RF signal from it using the antenna array. The signal is detected at each antenna and phase samples are recorded. The phase sample data is used in angle-related functions, such as angle of arrival and angle of departure algorithms to calculate the direction of the asset.
