Dynamic Spectrum Management
Seong Taek Chung · 2007
Abstract Dynamic spectrum management (DSM) dramatically improves the speed of Digital Subscriber Line (DSL) services. When the highest level of coordination is available, up to 500 Mbps can be realized for a single twister pair. With the medium or low level of coordination, the data rate can still be significantly improved over current data rate. In practice, the level of attainable coordination varies depending on each service provider’s situation: deployment scenario, government regulation, etc. This chapter provides a guideline for each service provider so that 500 Mbps per user becomes viable in the near future.
