Hello, I have a question about what exactly is DFS mode and how do I implement it. I have not found Info about this on the forums. Apparently everyone has it on dfs mode=none
Regards,

1. How often can Mikrotik DFS change channels?DFS is dynamic frequency selection. In theory, in a perfect world, it picks the best frequency automatically and uses it.
1. How often can Mikrotik DFS change channels?
2. When there is a channel change, is it coordinated with station units, or do they disassociate and scan?
3. If coordinated, how long is the outage in ms?
Which is not really OK in ETSI countries. There are more things you have to do (re-scan every 24 hours etc.)...DFS with radar detect will change the frequency only when it identify a military radar in it's frequency
What exactly is classified as a "military radar" ? How is this decision made ?DFS without radar detect will select and choose a frequency only once.
DFS with radar detect will change the frequency only when it identify a military radar in it's frequency
Ciao, che configurazioni usi per le radio, Access Point o bridge?We implemented a private civic hiperlan network in venice ancient water city.
Initially we set DFS to radar detect (to be compliant with italian regulations).
In this environment, probably with a lot of boats radar we found poor performances caused by strange DFS activity.
We found each RB using 5180 frequency.
To get best troughput we setted manually each RB to a free channel and DFS to none.
ROS was 2.9, several versione because RB buying was in different times.
No word that it also work on a Client, only on a AP. But ETSI regulation say: If the Client don't support DFS/DFS2, your max. TX-Power is 200mWatt EIRP..dfs-mode (none | radar-detect | no-radar-detect; default: none) - used for APs to dynamically
select frequency at which this AP will operate
• none - do not use DFS
• no-radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is
with the lowest amount of other networks detected
• radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with
the lowest amount of other networks detected, if no radar is detected in this channel for 60
seconds, the AP starts to operate at this channel, if radar is detected, the AP continues searching
for the next available channel which is with the lowest amount of other networks detected
dfs-mode (none | radar-detect | no-radar-detect; default: none) - used for APs to dynamically select frequency at which this AP will operate
none - do not use DFS
no-radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest amount of other networks detected
radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest amount of other networks detected, if no radar is detected in this channel for 60 seconds, the AP starts to operate at this channel, if radar is detected, the AP continues searching for the next available channel which is with the lowest amount of other networks detected
Now is set as none.dfs-mode (none | radar-detect | no-radar-detect; default: none) - used for APs to dynamically select frequency at which this AP will operate
none - do not use DFS
no-radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest amount of other networks detected
radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest amount of other networks detected, if no radar is detected in this channel for 60 seconds, the AP starts to operate at this channel, if radar is detected, the AP continues searching for the next available channel which is with the lowest amount of other networks detected
if you add some radar later, nothing will happen
