Future allocation utilization

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
