Abstract

Wireless communication link bandwidth utilization monitoring apparatus and methods are disclosed. Utilization of bandwidth on a wireless communication link is monitored to generate bandwidth utilization information. In order to provide a record of the distribution of bandwidth utilization, durations of bandwidth utilization above respective different thresholds might be determined. Such distributions could be useful for such purposes as network analysis and/or customer billing based on actual wireless bandwidth usage. Bandwidth utilization information may be collected from multiple wireless link nodes, illustratively the wireless link nodes at both ends of monitored wireless communication links, to allow total bandwidth utilization for bi-directional communications over the monitored links to be determined.
