  • Patent number: 9560531
    Abstract: A method and system for joint wireless and fixed network optimization for heterogeneous cellular networks includes performing a feasibility evaluation for an x-haul network comprising at least one of a fronthaul network and a backhaul network, after determining base station locations and radio frequency (RF) parameters. The feasibility evaluation may determine, based on a network graph, which small cell locations are accessible according to actual network demand and based on cost metrics for different types of network links.
