  11. Static Spectrum Management is Limited in Its Ability to Improve Spectrum Utilization Efficiencies Future Allocation & Utilization • Fixed Spectrum Assignments Lead to Inefficient Spectrum Utilization • Opportunities Exist in Time, Frequency, and Geography • RF Spectrum Allocated by Policy • Allocations, Assignments, and Incumbents Vary by Country Heavy Use Heavy Use Sparse Use Medium Use • Observations Show Bands of Local Heavy and Sparse Activity • Temporal Usage Characteristics Vary by Band & Service • Potential for Usage Dependent on Incumbent Service & Equipment Richard Paine, Boeing
