1 2/9/ IEEE Standards Coordinating Committee 41 Dynamic Spectrum Access Networks Report By Joanna Guenin to IEEE-SA Standards Board 27 September 2007

2 2/9/ Presentation Outline Introduction/Update –Background –Standards Developing Subgroups –Accomplishments What is SCC41 and why do we care? –Scope –Key Drivers –Challenges and Opportunities –Next Steps

3 2/9/ Background Early 2005P1900 Standards Committee established under joint sponsorship of ComSoc and EMC. The objective of this effort is to develop standards to support new technologies for advanced spectrum management for next generation radio systems. March 2007SASB approved SCC41 in March The work of the IEEE 1900.x Working Groups continues under SCC41. April 2007Held 1st inaugural meeting in Dublin, Ireland. July 2007Held 2nd inaugural meeting in Boulder, CO. December rd Plenary to be held in Berlin, Germany. 2008Three plenaries to be held in Washington DC, Tokyo Japan, and Chicago IL.

4 2/9/ SCC41 Standards Development Subgroups P WG- Terminology and Concepts for Next Generation Radio Systems and Spectrum Management P WG- Recommended Practice for Interference and Coexistence Analysis P WG- Recommended Practice for Conformance Evaluation of Software Defined Radio (SDR) Software Modules P WG - Architectural Building Blocks Enabling Network- Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks P1900.A SG- Dependability and Evaluation of Regulatory Compliance for Radio Systems with Dynamic Spectrum Access

5 2/9/ SCC41 Officers Co-Chair: Stephen Berger, TEM Consulting Co-Chair: Joanna Guenin, Motorola Vice Chair: Kalle Konston, Alion Science Secretary: Bernie Eydt, Booz Allen Hamilton Treasurer: John Chapin, Vanu

6 2/9/ SCC41 Accomplishments Working Groups making strong progress: –P in ballot –P passed 1 st Sponsor Ballot and currently in comment resolution and recirculation –P project issue resolved and PAR submitted to change scope –P 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

7 2/9/ SCC41 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.

8 2/9/ Motivations 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

9 2/9/ Complex technology, regulatory, business, standards and legal issues need to be solved to bring the benefits of these advanced technologies to fruition 1.Regulatory FCC Proceedings on Cognitive Radio Ofcom Consultation on DySPAN European Radio Spectrum Policy Group Japans MIC 2.Technology Research Mitolas work WWRF DARPA XG EU Framework Projects: E2R Conferences and Symposiums: DySPAN, Crowncom, Cognets… 3.Standards –IEEE 802 –ETSI –SDR-FORUM –ITU-R 4.Industry Coalitions –The TVWS coalition

10 2/9/ CR – Cognitive RadioPBAR – Policy-Based Adaptive Radio RFI – Request for InformationSCR – Software Controlled Radio SDR – Software Defined RadioSR – Software Radio 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. Increasing Flexibility and Reconfigurability SCR SCR + SDR baseband (for some applications) Ideal Software Radio SCR + SDR baseband + SDR RF Hardware Radio : First SDR device approved by FCC 1995: First RFI on SDR SR SDR Increasing use of software in advanced radios CR PBAR Hardware radio includes firmware and therefore may have significant operational flexibility.

12 2/9/ Relevant 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?

13 2/9/ Relevant 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 …….

14 2/9/ Challenges & 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.

15 2/9/ Next 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!
