After an AP with DFS is powered on it performs a channel availability check on its main carrier frequency for 1
minute, monitoring for the radar signature without transmitting. If no radar signature is detected during this minute,
the module then proceeds to normal beacon transmit mode. If it does detect a radar signature, the frequency is
marked for a 30 minute non-occupancy period, and the module moves to its 1
st
alternate carrier frequency. The AP
continues this behavior through its 2nd alternate frequency if needed and then waits until the first frequency ends
the 30 minute non-occupancy period. While operating, if the AP detects a weather radar signature it marks the
current carrier frequency for a 30 minute non-occupancy period and moves to check the next-in-line carrier
frequency.
An SM does not begin transmission until it detects a beacon from an AP. If APs are not transmitting, SMs will be
silent.
