ITU-R Activities Impact on ITS Paul Najarian U.S. Dept. of Commerce National Telecommunications and Information Administration
INTERNATIONAL TELECOMMUNICATION UNION A Specialized Agency of the United Nations in the field of Telecommunications An intergovernmental organization, bringing together governments and industry, to regulate and coordinate the operation of global telecommunication networks and services Consists of Member States & Sector Members representing public and private companies and organizations with an interest in telecommunications
INTERNATIONAL TELECOMMUNICATION UNION Based in Geneva, Switzerland 189 Member nations; Over 650 sector members History Founded in 1865, in Paris, as the International Telegraph Union, to interconnect telegraph across international borders (among 20 countries) Held first radio conference in 1906, in Berlin Other impetus/catalyst in 1912!!! Became the International Telecommunication Union, 1 Jan. 1934 Convergence of telegraph and radiotelegraph Absorbed/Merged as a UN Agency, 15 Oct. 1947 http://www.itu.int
ITU ORGANIZATION Plenipotentiary Conference Administrative Council Secretary General Coordination Committee Radiocommunication Sector (R-Sector) Telecommunication Standardization Sector (T-Sector) Telecommunication Development Sector (D-Sector) World Conference on International Telecommunications
ITU Conduct of Work Through the World Radiocommunication Conferences (WRCs) Or A Treaty-based approach Through the Radiocommunication Assembly (RA) Via a set of Study Questions assigned to specific Study Groups
WORLD RADIOCOMMUNICATION CONFERENCES (WRCs) Revise the Radio Regulations and any associated Frequency Assignment and Allocations Allocate spectrum to general radio services Identify spectrum for specific uses such as 3G Establish spectrum use coordination methods Set international rules for radio equipment operation Address any radiocommunication matter of worldwide character
WORLD RADIOCOMMUNICATION CONFERENCES (WRCs) Develop Agenda Items and questions for study by the Radiocommunication Assembly and its Study Groups in preparation for future Radiocommunication Conferences Use a Regional approach to progress the work Held 3-4 year intervals, 140 countries, 2000+ delegates, treaty agreement Next WRC scheduled Oct. 22 Nov. 16, 2007
REGIONAL SPECTRUM MANAGEMENT FORA Inter-American Telecommunication Commission (CITEL) (35) Caribbean Telecommunications Union (15) North Atlantic Treaty Organization (46) African Telecommunications Union (ATU) (46) European Conference of Postal and Telecommunications Administrations (CEPT) (43) Arab Spectrum Management Group (22) Asia-Pacific Telecommunity (APT) (35) Each Nation has Sovereignty Over the Use of its Spectrum
RADIOCOMMUNICATION ASSEMBLY Held immediately before each WRC Assigns Study Questions to Study Groups Responds to WRCs Sets work program for Study Groups Establishes operating procedures Approves Recommendations
RADIOCOMMUNICATION STUDY GROUPS SG1 Spectrum Management SG3 Radiowave Propagation SG4 Fixed-Satellite Service SG6 - Broadcasting SG7 Space Services SG8 Mobile, Mobile-satellite, Radiodetermination, Amateur SG9 Fixed Service Special Committee On Regulatory/Procedural Matters
EXAMPLE STUDY GROUP STRUCTURE SG 8 mobile, radiodetermination, amateur and related satellite services WP 8A land mobile except IMT- 2000; amateur and amateursatellite service WP 8B maritime mobile service including GMDSS; aeronautical mobile service and radiodetermination service WP 8D all mobile-satellite services and the radiodetermination satellite service WP 8F IMT-2000 systems beyond and IMT-2000
WORLD RADIOCOMMUNICATION CONFERENCE 2007 (WRC-07) Agenda Items of interest to ITS A.I. 1.4 Identification of Frequencies for systems beyond IMT-2000 A.I. 1.9 Satellite component of A.I. 1.4 A.I. 7.2 Future Agenda Items Ship and Port Security (Maritime ITS) Unmanned Aerial Vehicles (UAVs) DSRC Harmonization (Canadian proposal)
AI 1.4: Studies on frequency-related matters for future development of IMT-2000 and systems beyond IMT-2000 The U.S. proposes NOC to the following bands in order to ensure protection of incumbent systems: 410-430 MHz 2700-2900 MHz (CITEL Proposal) 3400-4200 MHz 4400-4990 MHz ITU-R sharing studies are ongoing but so far show potential for interference to existing systems.
AI 1.4: Identification of spectrum for IMT- 2000 and systems beyond (advanced wireless technologies) Conversion to digital broadcast television technologies will improve spectral efficiency and thereby make spectrum available for other applications Unique propagation and coverage characteristics of freed up spectrum are very important especially in areas with low population densities and/or limited telecommunications infrastructure It may take time but eventually broadcast television world wide will transition to digital technologies Telecommunications equipment manufacturers and service providers need lead time and regulatory certainty to implement services in new frequency bands Timing of WRC-07 is highly advantageous start of transition to digital TV and introduction of new advanced wireless technologies U.S. proposes: allocate 698-806 MHz allocated to the Mobile Service identify 698-806 MHz for IMT use
AI 1.4: Identification of spectrum for IMT-2000 and systems beyond (WiMAX) WiMAX meets or exceeds the technical requirements for IMT-2000 Many countries plan spectrum auctions (e.g., 2.5 GHz band) soon after the WRC-07 -- WiMAX should not be excluded from these auctions It is imperative for WiMAX to be recognized as IMT- 2000 technology
AI 7.2: Future Agenda Items Consider spectrum requirements and possible additional spectrum allocations to support enhanced ship and port security Consider spectrum requirements and possible additional spectrum allocations in the aeronautical mobile and/or aeronautical mobile satellite service to support the operation of unmanned aerial vehicles (UAVs) Canadian proposal to CITEL seeks to include an effort to harmonize bands for DSRC
Proposal for ITST2008 Research Topic Factors Is there a role for UAVs in ITS? Coverage Area and mobility Replaces fixed infrastructure Rural aspects Operational costs What are the technical specifications/requirements for such system? What are the standards and regulatory considerations?
ITS Activities in WP 8A (through Study Group Structure) Study Question on Transport Information and Communication Systems (TICS) introduced by Canada in 1994 (Question 205) What are the elements of TICS that require global harmonization? What are the spectrum requirements for TICS? What are the inter-connect requirements between TICS and Land Mobile Communications Systems?
ITS Activities in WP 8A A previous Study Question was introduced in 1982, and later assigned to TICS Study Question 51 on Automatic Determination of Location and Guidance in the Land Mobile Service This Study Question was introduced by Germany, long before the emergence of the ITS industry The intent was to standardize Automatic Vehicle Location (AVL) and guidance system for Dispatch Operations
Accomplishments To Date A Step-by-Step approach ITU-R M.1310 Transport information and control systems (TICS) - Objectives and requirements (10/97) ITU-R M.1451 Transport information and control systems: functionalities (05/00) ITU-R M.1452 Transport information and control systems Low power short-range vehicular radar equipment at 60 GHz and 76 GHz (05/00) ITU-R M.1453-2 Intelligent Transport Systems - Dedicated Short Range Communications (DRSC) at 5.8 GHz (06/05)
Accomplishments To Date -cont. Handbook on ITS As Volume 4 of the Land Mobile Handbook (In Publication) The intent is to provide a complement to the ITU-R Recommendations, as well as additional information to Developing Countries
Pending Work Preliminary Draft New Recommendation on Millimeter wave applications for ITS Possibility for completion in June 2007 Preliminary Draft New Recommendation on Broadband ITS Radiocommunications in the 5.9 GHz Depends on progress in IEEE 802.11(p) Preliminary Draft New Recommendation on Vehicle Information and Communication System (VICS) Difficult to achieve global harmonization due to potential interference to Mobile Satellite Services (downlink)
For ITST2008 Let s see some papers on: Use of ITS in cargo/port security or border crossing The role of UAVs in ITS (perhaps even a system design) Thank you for your consideration
