Then, for the access points, the computer system may compute co-channel interference (CCI) metrics based at least in part on the information about the access points and the one or more communication-performance metrics. Moreover, the computer system may select channels and channel widths of the access points based at least in part on the CCI metrics, a graph representation of the access points and a CCI criterion, where nodes in the graph representation correspond to the access points and edges in the graph representation correspond to communication between the pairs of access points. Next, the computer system may provide, addressed to the access points, second information specifying the channels, the channel widths and/or the transmit power of the access points. ## Claims ### Claim 1 A computer system, comprising: an interface circuit configured to communicates with access points, wherein the computer system is configured to: receive, associated with the access points, information about the access points and specifying one or more communication-performance metrics associated with the shared band of frequencies;
