Abstract
A radio frequency scanner system for mobile network testing includes at least one switchable directional antenna assembly, a radio frequency receiver, and a processing circuit. The antenna assembly includes several directional antennas oriented in different directions. The radio frequency receiver is configured to process the radio frequency signal received by the antenna assembly, thereby converting the at least one radio frequency signal to a baseband signal. The processing circuit is configured to process at least two baseband signals associated with two different directional antennas in order to determine an angle of arrival (AoA) of the at least one radio frequency signal with respect to the at least one antenna assembly. The processing circuit is configured to estimate a geographic location of a base station emitting the at least one radio frequency signal based on the angle of arrival of the at least one radio frequency signal.
