Abstract

Novel tools and techniques might provide for implementing combined broadband and wireless self-organizing network (“SON”) for provisioning of services. In some embodiments, a computing system might receive, from one or more first sensors and one or more second sensors, first operational states of fixed broadband network nodes and second operational states of wireless network nodes, respectively. The computing system might analyze the received first and second operational states, might determine an optimal network pathway and/or an optimal network backhaul pathway, and might establish the optimal network pathway and/or the optimal network backhaul pathway, through a determined combination of fixed and wireless network nodes, thereby implementing the combined broadband and wireless self-organizing network (“SON”) for provisioning of services.
