Telecommunications Industry Association (TIA) Updates Wireless Communications Systems Performance Standard

FCC "Spectrum Refarming" Created Need for New Methodology to Address Compatibility, System Performance and Interference

Arlington, Va. - The Telecommunications Industry Association (TIA), the leader in advocacy, standards development, business development and intelligence for the information and communications technology (ICT) industries, has published TIA Bulletin TSB-88.1-C, Wireless Communications Systems Performance in Noise-Limited Situations, Part 1: Recommended Methods for Technology-Independent Performance Modeling. TSB-88.1-C supersedes TSB-88-B (including addendum TSB-88-B1).

The FCC's "spectrum refarming" of existing frequency bands, the proposed 800 MHz band reorganizations and new allocations in the 700 MHz band, along with increasing reports of interference, dictated that TIA update the standard for performance modeling with the effects of single or multiple potential distortion sources for public-safety and other land mobile communications systems.

Limited to frequencies below 1 GHz, TSB-88.1-C defines methodology for assessing and addressing compatibility issues, system performance and interference, including:

• Performance parameters
• Co-channel and off-channel users
• Internal and external noise sources
• Equipment non-linearity
• Transmission path geometry and transmission loss modeling
• Delay spread and differential signal phase
• Over-the-air and network protocols and
• Performance verification

The standard TSB-88.1-C provides a recommended best practice reference for developers and suppliers of land mobile communications system design, modeling, simulation and spectrum management software and automated tools.

TSB-88.1-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. To obtain copies of the document, contact IHS International at 800.854.7179 or visit http://global.ihs.com.
