"Type 7 Radar Detection" - What does it mean?

[joegreat]

Hi,

Today I found a new and interesting messages in the Syslog.log of my AC68U unit:

Mar  5 15:22:47 kernel: SKIPPED false Type 7 Radar Detection. min_pw=6 pw_delta=0 pri=9498 fm_min=1030 fm_max=0 nconsecq_pulses=4. Time from last detection = 40956, = 682min 36sec. Detected pulse index: 0
Mar  5 15:25:49 kernel: SKIPPED false Type 7 Radar Detection. min_pw=7 pw_delta=0 pri=17495 fm_min=1030 fm_max=0 nconsecq_pulses=4. Time from last detection = 183, = 3min 3sec. Detected pulse index: 0
Mar  5 15:27:19 kernel: Type 7 Radar Detection. Detected pulse index=0 fm_min=1030 fm_max=0 nconsecq_pulses=4. Time from last detection = 90, = 1min 30sec 
Mar  5 15:28:49 kernel: Type 7 Radar Detection. Detected pulse index=0 fm_min=1030 fm_max=0 nconsecq_pulses=4. Time from last detection = 90, = 1min 30sec

I guess, that this could be realated to the new DFS feature for 5GHz WLAN...

With kind regards
Joe

Yeah, it has to do with the DFS channels. It will reduce power / jump channels when it detects signals like that. That does not affect the old lower and upper 5Ghz channels.
