Abstract
An analyzer can obtain data regarding signal characteristics in each of multiple communication channels within an access network. The analyzer can use that data to create signatures corresponding to each of the multiple channels. Based on similarities between signatures, the analyzer may then identify clusters of signatures associated with devices that share channels or portions of channels.
