Every new innovation in connected devices promises exciting possibilities for the future, but it also means greater demand for spectrum, a critical and limited resource used both by the public and private sectors.

NTIA is committed to ensuring that the government’s use of this valuable resource is as efficient and effective as possible. But what does it mean to be an efficient user of spectrum? And how can future systems make better use of spectrum? NTIA’s research laboratory, the Institute for Telecommunications Sciences (ITS), digs into these questions in a new report providing a thorough survey of the history of spectrum efficiency. ITS reviewed more than 50 years of studies examining domestic and international spectrum efficiency to hone insights for future research.

The report found broad consensus on fundamental spectrum efficiency metrics, which consider increasing productive spectrum use and reducing spectrum blocking. Studies also agreed that spectrum efficiency metrics are most appropriate for comparing similar spectrum dependent systems or for optimizing the deployment of similar systems within a frequency band.

Based on the research, ITS makes a number of recommendations addressing spectrum sharing, and suggestions for how best to focus future spectrum efficiency studies to enable the United States to maximize spectrum opportunities.
