NOISE AND IMPAIRMENT LOCALIZATION

Various techniques include detecting noise resulting from data network impairments and analyzing the noise to determine a likely source and location of the data network impairments. The analysis is used to generate noise reports that instruct network technicians how to check network devices for network impairments. The instructions can be provided on portable electronic devices that are further configured to receive data characterizing any impairments identified at the network devices. The data generated by the network technicians can be used to improve the ability of the techniques to correctly identify the source of data network impairments.
