  • Diagnosis of cellular network element states using radio frequency measurements
    Patent number: 9532252
    Abstract: Techniques for monitoring and diagnosing states of wireless network elements having a known impact on uplink interference are presented. In an aspect, a method includes receiving, by a system including a processor, diagnostic data for a cellular network including strength data representative of strengths of radio frequency signals, prior to demodulation, respectively received at a plurality of antennas of a base station of the cellular network over a defined duration of time and at a defined sampling rate. The method further includes, based on analyzing the strength data by the system, determining by the system, a state of a network element of the cellular network.
