Devices, methods and instructions encoded on computer readable media are provided herein for estimation of the available bandwidth in a frequency channel shared by a first access point and at least one neighboring access point. In one example, an impact value that represents the impact of traffic associated with the neighboring access point on the first access point is calculated. Based on the impact value, a first utilization metric associated with the first access point is generated. The first utilization metric represents the bandwidth available on the frequency channel in the presence of the traffic associated with the neighboring access point.
