Example Improvements of Dynamic Spectrum Management ( 089 )

This information-only contribution defines some potential dynamic spectrum-management methods and provides examples of potential improvements in their use. This contribution is not meant to provide sample text or methods for dynamic spectrum management, but rather to motivate study. This contribution investigates two types of spectrum management: static and dynamic. Dynamic spectrum management allows spectrum to be allocated as needed, rather than a static spectrum management that necessarily bases itself on worst-case analysis, and thus dynamic spectrum always performs better. This contribution shows realistic situations in which the level of improvement for dynamic spectrum management is large. Both linelevel and packet unbundling are considered with dynamic spectrum management. __________________________________________________________________________________ NOTICE This contribution has been prepared to assist Standards Committee T1 Telecommunications.
