DoD Spectrum Challenges
OPERATIONAL Net-centric operations, more joint
operations

• Net-Centric Warfare
• Higher bandwidths
• Greater mobility
• Greater agility
• Higher tempo

TECHNICAL Four decades of rapid wireless
technology development.

Ideas

• INDUSTRY/GOVERNMENT PARTNERSHIP
• Develop and reward new ideas/approaches for
  emerging technologies
• Address efficient spectrum utilization and
  waveform developments
• Minimize interference in selected frequency bands
  (Multi-band?)
• Extensive Testing
• Impact of new technologies
• Mitigate spectrum support issues prove spectrum
  efficiencies
• Still meet operational needs.
• Coordination and Decision
• Rethink current environment
• Different government entities (Spectrum Centers,
  DISA, FAA, etc)
