Standards Organizations
The Association of Public-Safety Communications Officials International, Inc. - APCO International - is the world's oldest and largest not-for-profit professional organization dedicated to the enhancement of public safety communications. ARCON's involvement with APCO has been through APCO Project 25, an industry-wide effort to set the recommended voluntary standards of uniform digital two-way radio technology for public safety organizations. It (P25) is the standard for interoperable digital two-way wireless communications products and systems. This standard has been developed under state, local and federal government guidance and Telecommunications Industry Association (TIA) governance, P25 is gaining worldwide
acceptance for public safety, security, public service, and commercial
applications. The published P25 standards suite is administered by the
TIA in their Mobile and Personal Private Radio Standards Committee
(TR-8). Equipment that demonstrates compliance with P25 is able to meet a
set of minimum requirements to fit the needs of public safety. These
include the ability to interoperate with other P25 equipment, for example
so that users on different systems can talk via direct radio contact. At a
minimum, a P25 radio system must provide interoperability with these two
mandatory P25 Standard interface components: While under contract to Rome Laboratory (USAF) in 1992, the Digital Speech Processing group at ARCON provided host laboratory, test laboratory and analysis capabilities to the initial APCO-25 Speech Coder Selection effort. This effort also included the collection of acoustic noise recordings from environments typical of the APCO-25 application. These environments included firefighter, police and emergency medical situations. This material was incorporated into the selection process. This effort resulted in the selection of the IMBE coder as an APCO-25 Standard. ARCON later worked with TIA TR-8 - APCO25 to provide for the distribution of these materials to interested parties. The European Telecommunications Standards Institute (ETSI) ETSI is an independent, non-profit organization, whose mission is to produce telecommunications standards for today and for the future. ETSI is officially responsible for the standardization of Information and Communication Technologies within Europe. The GSM wireless telephone network within Europe is an example of ETSI's ability to bring together diverse commercial interests in the standardization process, The Digital Speech Processing group at ARCON has worked closely with the ETSI STC SMG11 committee on the standardization of voice coders for the GSM system. In the summer of 1998 ARCON received a request to provide the Host Laboratory function for the initial Adaptive Multi Rate (AMR) coder selection effort. ARCON has continued its involvement with ETSI and has provided Host Lab services for the AMR characterization effort, the AMR Wide Band coder selection and the AMR Noise Suppression selection.
3GPP The original scope of 3GPP was to produce globally applicable Technical Specifications and Technical Reports for a 3rd Generation Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes). The scope was subsequently amended to include the maintenance and development of the Global System for Mobile communication (GSM) Technical Specifications and Technical Reports including evolved radio access technologies (e.g. General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE)). The 3GPP standardization committees took over much of the responsibilities of the groups within ESTI in which ARCON was active. The 3GPP working group that ARCON has remained active in is the Technical Specification Group - Services & Systems Aspects - Working Group 4 Coders (TSG SA WG4). ARCON's Digital Speech Processing group was directly involved in 3GPP's characterization of the ETSI Adaptive Multi Rate (AMR) narrow band coder acting as Host Laboratory, one of the Test Laboratories and as the Global Analysis Laboratory. ARCON also provided Host and Test Lab functions for the AMR Wide Band extension characterization project for 3GPP. In 2003 ARCON performed a communicability test for 3GPP on the AMR coder under VoIP conditions.
Telecommunications Industry
Association (TIA) The Telecommunications Industry Association (TIA) is the leading U.S. non-profit trade association serving the communications and information technology industry, with proven strengths in market development, trade shows, domestic and international advocacy, standards development and enabling e-business. Through its worldwide activities, the association facilitates business development opportunities and a competitive market environment. TIA provides a market-focused forum for its member companies, which manufacture or supply the products and services used in global communications. ARCON's involvement with TIA has been through two Standards committees, TR-45 and TR-8 -APCO25. Within TR-45 ARCON has worked with two subcommittees TR45.3 and TR-45.5, TR-45 Mobile and Personal Communications Systems Standards, provides performance, compatibility, inter-operability, and service standards for mobile and personal communications systems. These standards pertain to, but are not restricted to, service information, wireless terminal equipment, wireless base station equipment, wireless switching office equipment, ancillary apparatus, auxiliary applications, inter-network and inter-system operations and interfaces. Subcommittee TR-45.3 Time Division Digital Technology - Mobile and Personal Communications Standards, is assigned the authority to develop performance, compatibility, and inter-operability standards for equipment that makes use of Time Division Multiple Access (TDMA) technology for radio access in a system that supports any combination of international, public, non-public, or residential mobile and personal communications. These standards pertain to service definition, wireless mobile station equipment, wireless base station equipment, ancillary apparatus, as covered by applicable Parts of the Federal Communications Commission (FCC) Rules. The scope of subcommittee TR-45.5 Spread Spectrum Digital Technology - Mobile and Personal Communications Standards is the consideration of Spread Spectrum Digital Technologies and the development of such wireless standards within, and in concert with the scope of the TR-45 Committee. It has the authority to develop performance, compatibility and interoperability standards for Spread Spectrum Digital wireless access systems that support any combination of international, public, non-public, or residential mobile and personal communications. These standards apply to service definition, mobile and portable station equipment, base station equipment, ancillary apparatus, as covered by applicable Parts of the FCC Rules. |

International
Telecommunication Union Standardization Sector ITU-T The International Telecommunications Union (ITU) is international organization within the United Nations System where governments and the private sector coordinate global telecom networks and services. The ITU Telecommunication Standardization Sector (ITU-T) is one of the three Sectors of the ITU. Its mission is to ensure an efficient and on-time production of high quality standards (Recommendations) covering all fields of telecommunications. The Digital Speech Processing group at ARCON was worked closely with two of the Standards groups within the ITU-T, SG16 Multimedia services, systems and terminals and SG12 End-to-end transmission performance of networks and terminals. ARCON provides Listening Lab, Host Lab, and Global Analysis services to the ITU-T in qualification, selection and validation test efforts of digital speech processing algorithms. |
