Dynamic Frequency Selection and IEEE 802.11h Transmit Power Control


Dynamic Frequency Selection (DFS) is the process of detecting radar signals that must be protected against 802.11a interference, and upon detection switching the 802.11a operating frequency to one that is not interfering with the radar systems. Transmit Power Control (TPC) is used to adapt the transmission power based on regulatory requirements and range information.
