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.
Claims18
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 Radio Frequency, RF, samples captured over-the-air or from a Common Public Radio Interface, CPRI, or an 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, said analysis including determining a relative power of said detected peaks with said relative power used to assign a severity estimation, wherein said determining a relative power includes obtaining a baseline power of a subset of said data and comparing an absolute power of said peak to said baseline power;
- and
- causing display of a user interface that includes a reporting of said relative power and the severity estimation with the user interface.
A test system comprising:
- a detector comprising a receiver configured to capture a stream of RF samples over-the-air or through connection to a Common Public Radio Interface, CPRI, or enhanced CPRI, eCPRI, link;
- a processor;
- and
- memory storing instructions that, when executed, cause the processor to:
- obtain data from one or more tests of a mobile network having at least one antenna, wherein the data includes a stream of Radio Frequency, RF, samples captured over-the-air or from a Common Public Radio Interface, CPRI, or an enhanced CPRI, eCPRI, link;
- process the data to detect peaks;
- perform an analysis of any detected peaks to identify any issues on the mobile network, said analysis including determining a relative power of said detected peaks with said relative power used to assign a severity estimation, wwherein said relative power is determined by obtaining a baseline power of a subset of said data and comparing an absolute power of said peak to said baseline power;
- and
- cause display of a user interface that includes a reporting of said relative power and the severity estimation with the user interface.
A non-transitory computer-readable storage medium having computer readable code stored thereon for programming a test system to perform the steps of:
- obtaining data from one or more tests of a mobile network having at least one antenna, wherein the data includes a stream of Radio Frequency, RF, samples captured over-the-air or from a Common Public Radio Interface, CPRI, or an 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, said analysis including determining a relative power of said detected peaks with said relative power used to assign a severity estimation;
- and
- causing display of a user interface that includes a reporting of said relative power and the severity estimation with the user interface, wherein said causing display includes a ranking of spectrum interferers by antenna based on the severity estimation and includes at least one spectrum interferer having a higher absolute power than another one spectrum interferer but ranked lower based on the severity estimation due to relative power.
