Dynamic Frequency Selection
What is Dynamic Frequency Selection (DFS)?
DFS is the process of detecting radar signals that must be protected against interference from 5.0 GHz (802.11a/h) radios, and upon detection switching the operating frequency of the 5.0 GHz (802.11a/h) radio to one that is not interfering with the radar systems. TPC is used to adapt the transmission power of a radio based on regulatory requirements and range information.
