In addition, ATPC (Automatic Transmit Power Control) is a feature to automatically adapt transmit power when the quality

of the link is more than sufficient to maintain a good communication with reduced transmit power. This feature is required

for FCC DFS. It works by monitoring the quality of the link and reducing the output power of the radio by up to 6 dB when

good link quality can still be achieved. When link quality reduces, the output power is automatically increased up to the

original power level to maintain a good link. For a full discussion of DFS, see Dynamic Frequency Selection/Radar

Detection (DFS/RD).
