Well as it stands to day it will not be able to because one of the requirements is continuously looking and detecting radar signatures. In their current implementation they only look for a short period after the interface been enabled but before it start transmitting. Next time it will look is if you change the interface settings or reboot the unit. DFS requires continuously checking and honestly I am not sure that 802.11 based hardware could do this without hardware modifications. But then I'm not a hardware engineer and not perfectly well versed with all requirements with the DFS protocol. I just know there are some people that tried to use MT to get a DFS certified solution and it failed to pass the requirements with the exception when it saw radar directly after the interface was enabled. From the looks of things it really never looks for radar signatures again after it gotten its initial good to go.
Is it possible to change the functionality in MikroTik to comply with DFS2 requirements on a software level/driver level without hardware changes I do not know. Just that as it is today it is a clear no go. / Eje -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tom DeReggi Sent: Tuesday, April 21, 2009 9:19 AM To: WISPA General List Subject: Re: [WISPA] is this router overloaded?

If it were true it would means that the DFS limit was hardware or 802.11a protocol based, because software ALWAYS has the option to be changed and modified to meet a specific requirements. I agree that MT's current DFS2 support would not pass FCC certification. But I don't see why it couldn't be expanded to be certifiable.
