Abstract

A system, method, and computer program product are provided for utilizing radio access network (RAN) information and mobile backhaul (MBH) network information to assess network site performance. In operation, a system receives information associated with a radio access network. Additionally, the system receives information associated with a mobile backhaul network corresponding to the radio access network. The system correlates the information associated with the radio access network with the information associated with the mobile backhaul network to create correlated information. Further, the system calculates scores for the correlated information. Moreover, the system calculates a score for a site associated with the mobile backhaul network utilizing the scores for the correlated information.
