I didn't think there was a difference between 5.4 and 5.3.

5.3G to DFS
Exactly, you just answers how the FCC practically detroyed the WISP
industry overnight.
Contractually and Guaranteeing that one does not interfere with other
Colocators, is a big problem now that 5.3G forces DFS.
Also note that some Equipment manufacturers do not distinguish the
difference between support for 5.3 versus 5.4. Meaning 5.3 and 5.4 are
included in the same hoppable channels for a link.
The problem is that for Radar detection, the radios only need to hop if a
very loud signal is heard, but the radio could be forced to hop to a
channel that interferes with another colocater, and not realize its
hurting it because interference is not always symetical. Meaning because
it doesn;t interfer with you, doesn't mean you don;t interfere with it.
DFS is a very unneighborly protocol, that just cares about itself (the
radio) and the DOD (Radar).
DFS features a Radio should support are, distinguishing whether hopping
to 5.3 versus 5.4 is allowed or jsut one or the other, and exclusing
certain channels from being hoppable channel candidates, and setting
preferred channels for hopping to.

Subject: [WISPA] DFS Rules
Can anyone give me the low down on the DFS Rules.
Are there any channels in the 5.3 section that is not affected by
radar?
We have some towers that have multiple radios with channel plans
that incorporate all 5ghz spectrum from ap's to backhaul links.
To loose the 5.3 to radar dramatically affects our network because now
I have to figure out how I'm going to fit all the radios in 5.8ghz.
Has this hindered anyone else and to what extent? Any ideas to squeeze
in radios on 5.8.
I heard 5.4 will be available, is his so and when?
