1. A resource allocation system for allocating wireless resources to each of the Base Station/Access Points (BS/APs) of a Radio Access Network (RAN) situated in a campus location of a wireless Enterprise Network (EN), comprising:
a path loss estimation unit for providing path loss data associated with the BS/APs in the campus location;
a network graph construction unit for constructing a network graph of the RAN responsive to the path loss data;
a domain proxy for determining available channels and a maximum power available for each of the available channels;
a Self Organizing Network (SON) unit including
a channel assignment unit for assigning the channels to the BS/APs responsive to the network graph;
a Physical Cell Identifier (PCI) allocation unit for determining PCI allocation for each assigned channel responsive to the network graph; and
a power assignment unit for assigning power to each of the BS/APs responsive to the network graph in an iterative process that incrementally reduces the power and observes the effect on the resulting throughput Cumulative Distribution Function (CDF);
wherein the RAN resource allocation system further comprises an Automatic Configuration Server (ACS) for implementing the channel assignments, PCI allocations, and power assignments.
