Update – Reconfigurable Radio Systems

This update provides information on the current activities and progress in reconfigurable radio systems, including cognitive radio and software-defined radio. It highlights the work being done in standardization bodies such as ETSI, IEEE, and ITU-R, and discusses the challenges faced in terms of market and regulatory issues. The update also explores the need for standards, policy, and conformity assessment in order for reconfigurable radio systems to succeed.

  1. Update – Reconfigurable Radio Systems T. Russell Shields Chair, Ygomi LLC

  2. Highlight of Current Activities • Most activity about reconfigurable radio systems (RRS), including cognitive radio (CR) and software defined radio (SDR), has been conducted in ETSI, IEEE, and ITU-R. Other contributions come from groups including the Wireless Innovation Forum • Working definitions of SDR and CR were adopted in 2009 • ITU-R WP1B is the responsible group for WRC-11 AI 1.19 • ITU-R WP5A is developing a report on a definition for CRS and input for WP1B • ITU-R WP5D is giving input to WP5A on CR related to IMT/3G • Market and regulatory issues, including potential benefits and potential complications, are also being studied

  3. Current Activities – ITU-R • Website: http://www.itu.int/en/ITU-R/pages/default.aspx • Most work related to RRS is done in SG1 (Spectrum Management) and SG5 (Terrestrial Services) • Selected SG1 WP1A work • [39] Annex 11 - Studies on cognitive radio systems (CRS) in relation to Resolution ITU-R 58 within Working Parties 1A and 1B • Selected SG1 WP1B work • [42] Annex 14 - Studies on cognitive radio systems (CRS) in relation to Resolution ITU-R 58 within Working Parties 1A and 1B • [42] Annex 01 - Preliminary draft revision of Recommendation ITU-R SM.1370-1 - Design guidelines for developing automated spectrum management systems

  4. Current Activities – ITU-R • Selected SG5 WP5A work • [198] Annex 22 - Working document towards a preliminary draft new Report ITU-R [LMS.CRS2] - [Cognitive radio systems [(CRS) applications] in the land mobile service] • [198] Annex 20 - Working document towards a preliminary draft revision of Report ITU-R M.2228 - Advanced intelligent transport systems (ITS) radiocommunications

  5. Current Activities – IEEE • IEEE activities on RRS are in IEEE 802.22 Working Group on Wireless Regional Area Networks (WRAN) • http://www.ieee802.org/22/ • IEEE 802.22.2-2012, Standard for Recommended Practice for Installation and Deployment of IEEE 802.22 Systems, was published on September 28th, 2012 • Ongoing projects include • IEEE P802.22.1 Advanced Beaconing • IEEE P802.22a, Management and Control Plane Interfaces and Procedures and enhancement to the Management Information Base (MIB) – Draft 1 is available • IEEE P802.22b, Enhancements for Broadband Services and Monitoring Applications – Call for contributions released

  6. Current Activities – WIF • Website: www.wirelessinnovation.org • Activity since GSC-16 • Events in Asia, Europe, and the U.S. • Recommendations to standards-making bodies and governments • White papers on RRS technical and business developments • Information Process Architecture Volume 2: Survey of IPA Like Systems • SCA Test, Evaluation and Certification Model Realization • TD-LTE in White Space • Top 10 Most Wanted Wireless Innovations – 2013 • Business Models for New Entrants in the SDR Tactical Radio Market • Selected events later in 2013http://www.wirelessinnovation.org/events_calendar • Terabit, San Francisco, USA, 4-5 June 2013 • SDR-WInnComm-Europe 2013, 11-13 June 2013 • Wireless China Industry Summit 2013, 11-13 September 2013

  7. Strategic Direction • Provide relevant strategic direction of the PSO on the topic, including observations (positive or negative), outcomes, target timeframes, collaborations, etc., for completion that the PSO foresees on the topic. During the GSC interactive panel, please be prepared to discuss the significance and potential impact of the strategic approach that the PSO is taking on this HIS.

  8. Challenges (1) • The market is moving very fast, complicating standardization • Debate continues over the role of standards in RRS • What needs to be standardized? Will setting standards so early in RRS development hurt innovation? • Several technologies are competing for de facto standard status • Regulatory bodies need to make sure that devices will meet current and future requirements • Most interest has been on the business and technology sides, but mature policy is also necessary for RRS to succeed • A conformity assessment apparatus is necessary • Regulators also need principles for considering questions unique to RRS • Example: whether to allow software updates without requiring a device to be recertified

  9. Challenges (2) • Existing services (especially public safety) need protection from interference that might result from SDR and CRS • Some standards and/or regulatory entities might want to exclude SDR/CRS from some bands • Some countries (e.g., the U.S., Canada) have not recommended regulatory changes or changes to ITU rules before RRS can be implemented, but other countries might • On the technology side, standards are needed for components that make CR networks secure from various kinds of DoS attacks, a generalized CR-MAC, and cross-layer design • Despite all of the efforts, the real need for vehicle manufacturers is the ability to build vehicles with radios that can be updated for new protocols over the life of the vehicle.

  10. Next Steps / Actions • Identify plans for the future, path forward, etc., and/or identify next steps/actions to be taken by the PSO.
