Doing a Google search, I think this is the most recent revision of the 5 GHz rules. It modified a previous order that would move from 15.247 to 15.407 for the entire band, which would have been very bad for us. Basically the use of antenna gain for PTP links would have been outlawed unless you employed expensive filtering. Out of band emissions would have been limited based on radiated power including antenna gain, not conducted power.
