  1. TIA 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 OMG and especially 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. Highlight of Current Activities – ETSI • See http://www.etsi.org/WebSite/technologies/Radio.aspx • ETSI TC ERM deals with radio technology standards • ERM WG RM is responsible for cooperation with the ERChttp://portal.etsi.org/portal/server.pt/community/ERM/306?tbId=305 • In 2010-2011, ERM RM made progress on several work items • TR102 137: “Use of radio frequency” • MI/ERM-RM-025: “Overview of alignment of ETSI standards with ERC Rec. 74-01” • DTR/ERM-RM-265: “Definition of radio parameters” • DTR/ERM-RM-266: “Approach to the validation of TC ERM deliverables (standards)” • MI/ERM-RM-267: “Usage of Quasi-peak detectors” • DTR/ERM-RM-268 (TR 103 028): “Relative Measurement Uncertainties (RMUs); Usage and effect of mathematical operations on them”

  4. Highlight of Current Activities – IEEE • IEEE 802.22-2011 (standard for WRAN using TV white spaces) was adopted in July 2011 • IEEE 802.16h (improved coexistence of 802.16-based networks in unlicensed bands) was published in June 2010 as an amendment to IEEE 802.16-2009 • IEEE 802.19 WG approved its operations manual in July 2011 • DYSPAN-1900.7 – White Space Radio has organized to specify IEEE P1900.7 for MAC sublayer(s) and PHY layer(s) of white space dynamic spectrum access radio systems

  5. Highlight of Current Activities – ITU-R • As of September 2011, various WPs in ITU-R have made progress on cognitive radio items • WP1B • CPM text on WRC-12 agenda item 1.19 • Draft WRC Resolution [A119-B2] for WRC-12 agenda item 1.19 • Responses are requested for the next WP1B meeting (proposed for June 2012) and subsequent meetings • WP5A • Working document towards a draft new Report ITU-R M.[LMS.CRS1] (Doc. 5A/TEMP/306) • Working document towards a draft new Report ITU-R M.[LMS.CRS2] (Doc. 5A/TEMP/309) • WP5D • Preliminary draft new Report ITU-R M.[IMT.CRS] (Doc. 5D/TEMP/542)

  6. Highlight of Current Activities – OMG • Object Management Group (OMG) Software-Based Communication (SBC) Domain Task Force (DTF) develops and promotes specifications for SDR devices, through activities including • Promotion of UML and model-driven technology • Development of specifications to improve interoperability of software-defined components • Promotion of software radio specifications • SBC DTF and the Wireless Innovation Forum – supported by several companies – are working on a commercial standard based on the SCA • OMG’s website (http://sbc.omg.org/) has shown little activity in this area in the last year

  7. Highlight of Current Activities – Wireless Innovation Forum (1) • See: www.wirelessinnovation.org • 107 organizational members • Activity since GSC-15 http://www.wirelessinnovation.org/events_calendar • 67th WInnForum Meeting, Schaumburg, IL, U.S.A., Sep. 13-15, 2010 • 68th WInnForum Meeting, San Diego, CA, U.S.A., Mar. 14-17, 2011 • 69th WInnForum Meeting, Brussels, June 20-22, 2011 • 70th WInnForum Meeting, Montreal, Sep. 12-15, 2011 • SDR’11-WInnComm will be held Nov. 29-Dec. 2 in Washington, D.C. • SDR’11-WInnComm – Europe will be held June 25-28, 2012, in Brussels

  8. Highlight of Current Activities – Wireless Innovation Forum (2) • Publications since GSC-16 • Dec. 2, 2010, WINNF-09-P-0012-V1.0.0: “Quantifying the Benefits of Cognitive Radio” • Sep. 14, 2011, WINNF-09-P-0006: “White Paper on SDR Technologies for the International Tactical Radio Market” • Oct. 2, 2011, Document WINNF-11-P-0014: “Top 10 Most Wanted Wireless Innovations”

  9. Highlight of Current Activities – Wireless Innovation Forum (3) • Selected Highlights of Work from the 67th-70th General Meetings (1) • Cognitive Radio Work Group is working on two projects: “Cognitive Radio Information Services Project (CRISP)” and “Information Process Architecture” • Public Safety SIG will continue to promote results from "Cognitive Radio Technology Survey for Public Safety Applications" • International Tactical Radio SIG is developing a report called “Business Models for New Entrants in SDR Tactical Radio Market”

  10. Highlight of Current Activities – Wireless Innovation Forum (4) • Selected Highlights of Work from the 67th-70th General Meetings (2) • DSA/White Space Database Interoperability Work Group plans to work on two documents: ”Database Synchronization Guidelines” and “Device Interoperability Specifications” • TD-LTE in White Space Task Group is working on a report called “TD-LTE in White Space” • Security Work Group is continuing work on a specification called "Security Requirements and Profiles Case Studies“ • Several work groups are focusing on aspects of software communications architecture for SDR (APIs, test and certification, implementation, etc.)

  11. 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

  12. 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.
