Advanced HF Spectrum Management techniques

The HF Bandwidth continues to be an important media for beyond-line-of-sight communications. Advances in modems and protocols and the continual improvements in HF communications techniques are making HF attractive for system planners for both short and long haul communications. With the demand for HF bandwidth expected to grow, this paper describes how the latest Advanced HF Spectrum Management techniques using Dynamic Frequency Selection (DFS) have the potential to improve the efficiency with which HF bandwidth is used, limit interference and reduce frequency congestion.
