Defense Spectrum Summit
DSO EST PROGRAM
• Emerging spectrum technologies directly affect
the manner in which the spectrum is accessed,
used, occupied, or managed; they comprise of
technologies that are being developed, or
existing but not yet implemented
• Program Goals
– Identify the opportunities and risks in the early stage of
spectrum technology development
– Influence and lead technology development to maximize
DoD spectrum utilization
– Ensure spectrum policies to accommodate the use of
technology to meet DoD mission requirements
– Outreaching to strategic partners to address hindrance
to DoD current and future spectrum access
Assured Spectrum Access When and Where Needed

EST Perspective on Spectrum
Demand
Spectrum Challenges
• The growing demand for spectrum from the commercial
sectors is accelerating
• Future wireless/mobile systems (4G) will provide ubiquitous
high speed data communications using the most cost
efficient access technologies
• Encroachment on DoD spectrum is expected to exacerbate
On-going Efforts
• EST’s technology tracking and assessment effort allows
DoD to better anticipate any positive and negative impacts
on DoD spectrum access
• EST is collaborating with various organizations to address
challenges.

EST Perspectives on
Standardization
• DoD is a major user of commercial technologies and products
• Industry standards are critical to ensure the success of any
mobile technology
• The large number of standards as well as the requirements for
interoperability and seamless mobility will demand the future
radio devices to
– Support multiple air interfaces
– Support seamless handoff among different systems
– Provide high quality consumer applications such as video, digital
camera, web-browsing, etc.
• The industry believes that functional integration is the answer for
the mobile devices in the near-term. However, wide adoption of
SDR technologies (particularly by commercial mobile devices)
won’t happen in the near-term
• Given the importance of SDR in DoD systems, EST has taken a
leading role to promote SDR related technologies and has
investigated policy implications concerning the certification of
SDR and CR devices.
• EST participates in standard organizations including ITU-R, IEEE,
SDR Forum, WiMAX Forum, etc.

EST Perspective on Technology
Convergence
• IP is the catalyst that enables the convergence of
different services on a common transport
platform
• Convergence of fixed and mobile services is
taking place
• Convergence of wireless communications
technologies using OFDM, MIMO, and Beam
Forming Antennas
• Convergence of radio system implementation
– Multi-radio for commercial devices
– SDR for DoD systems
• EST is investigating policy and regulatory
implications of these technologies

EST Perspective on Dynamic
Spectrum Access (DSA)
• DSA will enable the transformation of the current spectrum
management (command and control) to a more flexible accessing
model
• Significant regulatory challenges remain in the areas of
– Spectrum sharing
– Waveform and device certification
– Policy verification and enforcement
– Security
• Technology maturity
– Sensor design
– Machine readable policy language
– Scalability
– Performance, cost, form factor
• Recognizing DSA’s implications to DoD, the DISA EST program is
– Monitoring the DSA technologies and collaborating with the XG
program on policy and regulatory issues
– Participating in the IEEE P1900 Standard Committee to advance
standardization of the DSA technology
– Tracking SDR related technologies and investigating policy
implications concerning the certification of SDR and cognitive radio
devices
– Participating in ITU-R, NTIA SDR WG

EST STRATEGY FOR DSA
TECHNOLOGIES
• Start with military-to-military applications
• Establish regulatory framework both nationally and
internationally to address DSA technologies
– ITU-R, ITU-T Working Group
– NTIA
• Outreach to regulatory bodies to promote DSA concept
• Gain acceptance of DSA concept
– NTIA in Certification process
– Spectrum regulators in ITU and other administrations
• Promote database and tools as part of a real-time SM
infrastructure
• Defense Spectrum Management Architecture (DSMA) “To
Be” View to include DSA capabilities and associated
transition strategy
• Encourage Acquisition Community to inject DSA
technologies into future procurement

EST Program On-Going Activities
• Lead Critical Technology Policy and Outreach Initiatives
– Lead DoD WiMAX WG to mitigate potential interference with DoD
Radar Systems in the 3400-3700 MHz band
– Develop candidate regulations and policies to accommodate
technology (collaborating with NTIA and leveraging FCC rulemaking)
• EST Workshops
– Provide insight into emerging technology and to guide development of
policies
– Forum for making recommendations on DOD spectrum policy and
investments in R&D spectrum-dependent technologies and systems
– 2nd Workshop will be held in April 2007
• Technology Trend Analysis
– Project technology evolution over the short, mid, and long terms
– Assist DoD programs to formulate spectrum technology strategies
• Continue Proactive Technology/policy Impact Assessments
– WiMax, UWB, Smart Antennas, Packet Protocols, Spectrum Access
Protocols, Cognitive Radio (DARPA XG), Advanced Radar, Mesh
Networks, Ad Hoc Network, SDR, Presidential Initiatives – WLG-E, etc.
