Can you point to any info on getting one?

If it's left in, we can use variants of 802.11 gear NOW, and for relatively 
cheap, as well.  Heck, whether it's in or out, it appears to be workable.  
Frankly, I could use it now.  I have no issues with distance and eirp for 2.4 
or 5.8 as it stands.  I mean, I can find ways of dealing with those 
limitations.   I can't deal with the interference nearly as well.  I found 
both UDC's and antennas that could be built to comply for 3650 NOW, and the 
idea of some interference free backhauls certainly sounds good.  Being 
required to pull them in a year or two doesn't sound catastrophic to me.

I read the last R & O quite extensively and decided that there's no real 
great advantage to 3650.  You can use 25 W ERP, but only if you use a 25 mhz 
wide channel.  The narrower the channel, the lower the erp limits.  Exactly 
how this plays out

Thus, using narrower slices of the spectrum is not encouraged. 

One other apparently odd "deficiency" is that there's no ERP distinction 
between P2P and P2MP.  You can use an omni at both ends of a P2P link without 
penalty, nor is there anything to encourage cleaner P2P use like the ISM 2.4 
and 5.8 rules. 

Personally, I think the FCC is holding out, trying to

Without rules to go by, I don't see ANYONE putting money into it.  

Any idea what kind of rules for what equipment is allowed?  What kind of 
certifications mechanism?   They hinted at "use any antenna" rules, which is 
fine, but if we're stuck with a part-15 type of "whole assembly" 
certification, we're going back to the "must buy only the big boy's 
solutions" which...may never exist, as you say.
