The TSB-88.x Series

The TSB-88.x series of bulletins provides guidance on the following areas:

• Establishment of standardized methodology for modeling and simulating various and different bandwidth-efficient technologies operating in a post “Refarming” environment or in new frequency band allocations;

• Recommended databases and propagation models that are available for improved results from modeling and simulation;

• Establishment of a standardized methodology for empirically confirming the performance of various and different bandwidth-efficient systems operating in a post “Refarming” environment or in new frequency band allocations, and;

• Combining the modeling, simulation and empirical performance verification methods into a unified family of data sets or procedures which can be employed by frequency coordinators, systems engineers, system operators or software developers;

The purpose of these documents is to define and advance a standardized methodology to analyze compatibility of different technologies from a technologyneutral viewpoint. They provide recommended technical parameters and procedures from which automated design and spectrum management tools can be developed to analyze proposed configurations that can temporarily exist during a “rebanding” migration process as well as for longer term solutions involving different technologies.

As wireless communications systems evolve, it becomes increasingly complex to determine compatibility between different types of modulation, different channel bandwidths, different operational protocols, different operational geographic areas, and application usage.

Thus, spectrum managers, system designers and system maintainers have a common interest in utilizing the most accurate and repeatable modeling and simulation capabilities to determine likely system performance. With increasing spectrum allocation complexity, both in terms of modulation techniques offered, channel bandwidths available and in the number of entities involved in wireless communications systems, a standardized approach and methodology is needed for the modeling and simulation of these systems, in all frequency bands of interest.

In addition, after deployment, validation or acceptance testing is often an issue subject to much debate and uncertainty. Long after a system is in place and optimized, future interference dispute resolution demands application of an industry accepted and standardized methodology for assessing system performance and interference.
