Metric name: Global throughput.

Metric description: Traffic going through the system over time (global throughput efficiency).

Metric measured property: Averaged over time.

Metric scale: bps.

Metric source: Global measure of traffic going through the system. Successful use of spectrum resources dynamically should increase the wireless network's capacity to accommodate higher traffic in bps.

Note: This metric is system dependent. Some systems, such as cellular systems, link this traffic demand to revenue making. The metric is not only interested in getting insight into achieving higher throughput, but the higher number of users that increases revenues. Some users' rates can be lowered but the service continues in order to accommodate more users as long as the service agreement is met.
