43、adband public safety network; The TSB-88 series of documents was prepared partially in response to specific requests from three particular user organizations: the Association of Public Safety Communications Officials, International (APCO), the Land Mobile Communications Council (LMCC) and the Nation

44、al Coordination Committee (NCC). In 2003, the National Public Safety Telecommunications Council (NPSTC) assumed the responsibilities of NCC.1This document, TSB-88.4, is intended to address performance modeling and the parametric values used to accomplish that modeling within the context described ab

46、 Recommended Methods for Broadband Performance Modeling 1. SCOPE 1.1. The TSB-88 Series The TSB-88 series of bulletins gives guidance on the following areas: Establishment of standardized methodology for modeling and simulating either narrowband/bandwidth efficient technologies or broadband technolo

47、gies; Establishment of a standardized methodology for empirically confirming the performance of either narrowband/bandwidth efficient systems or broadband systems; Aggregating the modeling, simulation and empirical performance verification reports into a unified “Spectrum Management Tool Kit” which

48、can be employed by frequency coordinators, systems engineers, software developers, and system operators; Recommended datasets that are available for improved results from modeling and simulation; and Providing current information for new and emerging bands. The purpose of these documents is to defin

49、e and advance a scientifically sound standardized methodology for addressing technology compatibility. This document provides formal structure and quantitative technical parameters from which automated design and spectrum management tools can be developed based on proposed configurations that can temporarily exist during a migration process or for longer term solutions for systems that have different technologies. As wireless communications systems evolve, the complexity in determining compatibility betwe
