A Deep Learning Approach for Detecting RF Spectrum Impairments and Conducting Root Cause Analysis (2022)

By Kevin Dugan, Justin Evans, Maher Harb; Comcast

In proactive network maintenance (PNM), a goal of downstream spectrum analysis is to identify customer devices with impairments in RF (Radio Frequency) spectrum. Identifying the type of impairment is useful in determining the general causation, which is leveraged to infer the geolocation of the impairment’s origin in the network. This paper describes the implementation of an automated, end-to-end solution that analyzes millions of sets of spectra and delivers PNM opportunities for the organization.
