Abstract: A method comprising obtaining, via a test system, data from one or more tests of a mobile network having at least one antenna, wherein the data includes a stream of RF samples captured over-the-air or from a Common Public Radio Interface (CPRI) or enhanced CPRI (eCPRI) link; processing the data to detect peaks; performing an analysis of any detected peaks to identify any issues on the mobile network, the analysis including determining a relative power of the detected peaks; and causing display of a user interface that includes a reporting of any the relative power. Determining a relative power includes obtaining a baseline of a subset of the data and comparing an absolute power of the peak to the baseline.

Abstract: An interference detection method and system and for providing information about at least one interference in I/Q data obtained over-the-air or detected on a link between a radio equipment controller (REC) and at least one radio equipment (RE). The method includes noise filtering a set of the FFTs into an averaged FFT, filtering the averaged FFT with a high-pass filter to remove low frequency components, applying a power threshold on the high-pass filtered FFT to select at least one candidate peak having a power greater than the power threshold; outputting information about the at least one candidate peak, which is a potential interference. The interference detection method further includes multi-lane processing and power shift compensation.

Abstract: In order to improve the analysis of the RF interferences, there is provided a peak selection assistance method for finding a local peak in an RF spectrum trace. The method provides a window on the spectrum trace display, which can be configured and/or moved by a user from user interaction on said user interface. When the window is defined, the method finds the highest peak within the window and optionally adds a marker on it. The method therefore snaps to the highest peak within the window. This improves the way of precisely detecting the maximum amplitude and the center frequency for any local peak on the spectrum.
