Telecommunications Industry Association (TIA) Updates Bulletin on Best Practices for Wireless Systems Performance

Methodology for Verification of Acceptance Testing Updated

Arlington, Va. – The Telecommunications Industry Association (TIA), the leader in advocacy, standards development, business development and intelligence for the information and communications technology (ICT) industry, has updated bulletin TSB-88.3-C, Wireless Communications Systems Performance in Noise and Interference-Limited Situations, Part 3: Performance Verification.

TIA issued TSB-88.3-C to help wireless companies meet compatibility needs, addressing the increasing spectrum allocation complexity, such as the FCC’s “spectrum refarming” of frequency bands, as well as various and new entities involved in a wireless communications system.

The update provides guidance in establishing standardized methodology of modeling the various interference mechanisms to support frequency coordinators in determining the best assignments for the available pool of frequencies and to validate and quantify the performance and compatibility of wireless communications systems that have varying modulations, geographic operating areas and applications. This empirical validation and quantification is integral to proofof- performance and acceptance testing, as well as to quantify the actual interference environment, versus simulated predictions in interference-limited systems.

TSB-88.3-C specifies conformance testing to determine whether a wireless communications system meets a user’s expectation of design reliability over the service area. It is anticipated that the document will serve as a recommended best practices reference for developers and suppliers of land mobile communications system design, modeling, simulation and spectrum management software, and automated tools.

TSB-88.3-C was formulated under the cognizance of the TIA TR-8: Mobile and Personal Private Radio Standards Engineering Committee's TR-8.18 Subcommittee on Wireless Systems Compatibility.

About TIA 
Currently in its 84th year, the Telecommunications Industry Association (TIA) represents the global information and communications technology (ICT) industry through standards development, advocacy, business opportunities, market intelligence and world-wide environmental regulatory analysis. TIA enhances the business environment for thousands of companies and individuals whose focus is broadband development and deployment (including wireless and landline infrastructure and services), information technology (IT) for commercial or residential application, Internet Protocol (IP) hardware, software and content solutions, and the convergence of voice, video and data (“triple play”) applications and evolution.

TIA co-owns NXTcomm, the tradeshow serving the ICT industry; is accredited by the American National Standards Institute (ANSI); serves as the secretariat for the Third Generation Partnership Project 2 (3GPP2); holds Board of Director positions on the International Telecommunication Union (ITU) TELECOM and USITO Boards; and hosts the USA pavilions in ITU trade fairs worldwide.

More than 1,100 subject matter experts and other industry leaders participate in TIA’s 70+ standards committees and TIA has produced more than 1,150 standards documents. From mobile and personal communications systems to fiber optics and cabling infrastructure, from vehicular telematics and terrestrial mobile multimedia to healthcare ICT, TIA’s engineering committees work to formulate positions and prepare international standards and reports for use by industry and government. TIA is accredited by the American National Standards Institute (ANSI).

In government affairs and international trade, hundreds of experts are at the table helping to advance and advocate initiatives on behalf of the industry – projects such as advancing global broadband deployment across wireline, wireless and cable platforms; advocating advanced spectrum management; encouraging policies to enable information access for persons with disabilities; seeking allocation of additional spectrum to advance wireless services and public safety; facilitating market opportunities by promoting full, fair and open trade and competition in international markets; and ensuring that the U.S. communications sector continues to be a leader in advanced research.

On the environmental front, TIA’s EIATRACK subscription-based web service, on the Web at www.eiatrack.com, enables companies to determine up-to-date information on environmental compliance of their products in various regions around the world.

TIA’s Board of Directors includes senior-level executives from ACS, ADC, ADTRAN, Alcatel- Lucent, ANDA Networks, ArrayComm, AttivaCorp, Avaya, Bechtel Communications, Inc., Cam Communications, Cisco Systems, Corning Incorporated, Ericsson, Inc., Graybar, Harris Stratex, Henkels & McCoy, Intel Corporation, LGE, Microsoft, Motorola, Nortel, OneChip Photonics Inc., Panasonic Computer Solutions Co., Qualcomm, Research In Motion, Sumitomo Electric Lightwave Corporation, Tellabs, Tyco Electronics, Ulticom, Inc., Verari Systems, Westell Technologies, Inc. and Zebra Technologies Corporation. Advisors to the Board include FAL Associates, ILS Technology, Orca Systems and Telcordia Technologies.

TIA membership enhances the ability of companies to prepare for the future of communications. TIA brings people and businesses together by helping the industry overcome technical and political barriers to communications. Visit www.tiaonline.org for details.
