## Abstract

A device may receive channel data associated with a channel provided between a network and a user device, and may calculate, based on the channel data, key performance indicator data that includes a plurality of key performance indicators for the channel. The device may multiply the plurality of key performance indicators by factors to generate factored key performance indicator data that includes a plurality of factored key performance indicators. The device may apply weights to the plurality of factored key performance indicators of the factored key performance indicator data to generate factored weighted key performance indicator data that includes a plurality of factored weighted key performance indicators. The device may calculate a quality indicator for the channel based on the factored weighted key performance indicator data, and may perform one or more actions based on the quality indicator for the channel.
