6SCC41 Accomplishments
- Working Groups making strong progress
- P1900.1 in ballot
- P1900.2 passed 1st Sponsor Ballot and currently
in comment resolution and recirculation - P1900.3 project issue resolved and PAR submitted
to change scope - P1900.4 drawing increasing global participation
- Mixed Entity/Individual process conflicts being
resolved - SCC41 Operating Procedures submitted to Audcom
for informal review - SCC41 website revamped and team in place to keep
information accurate and current - Competent, energetic Management team to move
SCC41 forward - Membership growing swiftly, currently at 60
- Drawing strong industry and academic interest and
participation
7SCC41 Scope
- SCC 41 sponsors standards projects in the area of
dynamic spectrum access networks and provides
coordination and information exchange between and
among standards developing activities of the
IEEE. - The scope of this SCC is to develop standards
related to dynamic spectrum access networks. The
focus is on improved use of spectrum. New
techniques and methods of dynamic spectrum access
require managing interference, coordination of
wireless technologies and include network
management and information sharing. IEEE-SA
Announcement, July 2007.
8Motivations for DySPAN
- Increasing demand for bandwidth and spectrum
- Decreasing supply of spectrum
- Incumbent service providers looking to cut cost
- New entrants looking for growth opportunities
- Governments wanting to offer broadband to the
masses
9Complex technology, regulatory, business,
standards and legal issues need to be solved to
bring the benefits of these advanced technologies
to fruition

SDR
Increasing Flexibility and Reconfigurability
SCR
Note SDR currently is practical for some
applications such as commercial wireless
basestations, but not for some wireless handsets.
Cost, power, size and weight are critical design
requirements that must be considered when
considering the use of advanced radio
technologies.

12Relevant Questions
- What are cognitive radio systems?
- What are the closely related radio technologies
(e.g. smart radio, reconfigurable radio,
policy-defined adaptive radio and their
associated control mechanisms) and their
functionalities that may be a part of cognitive
radio systems? - What are the key technical characteristics,
requirements, performance and benefits are
associated with the implementation of cognitive
radio systems? - What are the potential applications of cognitive
radio systems and their impact on spectrum
management? - What are the operational implications (including
privacy and authentication) of cognitive radio
systems? - What are the cognitive capabilities that could
facilitate coexistence with existing systems in
the mobile service and in other
radiocommunication services, such as broadcast,
mobile satellite or fixed? - What sharing techniques can be used to implement
cognitive radio systems to ensure coexistence
with other users? - How can cognitive radio systems promote the
efficient use of the radio resources?
13Relevant Standards Topics
- Certification of SDRs and CRs
- Regulatory enforcement of spectrum etiquettes
- Opportunistic secondary use of spectrum
- Interference mitigation techniques such as
Spectrum Sensing, geolocation, beacons - Cooperative Spectrum sharing/pooling
- Priority and tiered use by public safety and
primary users - Spectrum auctions, Spectrum leasing
- Dynamic spectrum allocation
- Cognitive spectrum management
- Policy based cognitive networks
- Security and Privacy
- And many more .
14Challenges Opportunities
- Challenges
- Regulations are pending but not yet in place.
- Many competing standards but also lots of gaps.
- Business cases are difficult in the beginning of
an emerging technological/regulatory environment. - Very complex technologies and unproven sciences.
- SCC41 needs strong participation from regulatory,
research and industry to create robust standards.
- Opportunities
- Cognitive Radios has the potential to
fundamentally change the spectrum allocation
paradigm. - Innovations in CR have the ability to implement
Protocols and Policies beyond traditional
Communications. - Many enabling technologies such as SDR, Policy,
are maturing and products are becoming a reality. - Global interest in CR Standards are increasing
and activities are escalating. - First set of regulations are happening standards
work feeds regulatory rules. - IEEE SCC41 is well positioned to play a leading
role in meeting the standardization requirements
in next generation radio systems.
15Next Steps for SCC41
- Create Visionary and Practical Technology Roadmap
to guide new projects - Identify, Nurture and Grow new standards projects
with industry and commercial relevance - Continue to build support infrastructure, e.g.
Regulatory - Build relationships with relevant standards and
industry organizations, e.g. Computer Society
802, SDR Forum, ETSI - Recruit industry and research experts
- Make SCC41 the place to do DySPAN standards work!
