To say its a Sham, may be a little harsh. OS8 does a better job at the issue however essentially if a PrismAC radio sees activity on the DFS channel you are on that is not part of its session list, it runs away and goes to another channel.
I think its physically impossible for these class of radio systems to actually detect the difference between Radar and just Signal on that band. I have had these discussions with UBNT, as well as others who use other radio products and I think false detect is a common problem on all platforms, not just UBNT. The FAA really threw a fit about this issue and the FCC made this a very strict certification requirement and so this is all that can be done. Even AF5 has this issue. We are going to start running a script that checks the radio ever 10 mins and if the freq has changed its going to change it back. I guess if there is a war going on between dfs logic and our logic, this may not work. I also wonder if the channel list can be limited. I don't see it in the UI. Perhaps UBNT folks listening can lend a hand here. *Alex Phillips* CEO and General Manager RBNS.net HighSpeedLink.net *WISPA.org Board of Directors ** (2011-2017)* *WISPA President (2015-2017)* *540-908-3993* On Thu, Oct 20, 2016 at 2:37 PM, James Craig via Ubnt_users < [email protected]> wrote: > Hi Guys, > > airMAX radios should only jump to another channel if a RADAR hit is > detected.
