Just means the last channel will also have radar detection enabled.   If you want to review that spec, just google "EN 302 502".  You will find latest V2.0.8 or V2.1.1  (both have same DFS rules).

But in my opinion, this document is an unequivocal confirmation of what the current rules are.     The attached doc states the date, the authority, the specs and the limits.   The web site has outdated information.

Thanks for the information. I think this matches what I had except where
I had cut the power limits in half because I suspected TPC was required
(5250-5350, 5470-5725, and 5725-5875 MHz based on EN 301 893 and EN 302
502). Is TPC not required in these ranges?

Thanks,
Seth
