Fred,Correct me if I'm wrong, but I am under the impression that 3.55 - 3.62 GHz (70 MHz) will be allocated to (7) 10 MHz PAL licenses, which will be auctioned per census tract. 3.62 - 3.70 GHz (80 MHz) will be allocated to GAA (General Authorized Access) with carve-outs for Incumbent Users such as the Satellite Earth Station Protection Zones and possibly Naval Radar entering an area.
Not quite. The band will not be divided like that, and PALs will not be assigned specific frequencies like PCS. A PAL grants the right to create a PAL Protection Area (PPA) within the owned census tracts. The SAS assigns the PAL channel. A PA licensee who claims multiple PALs in a location will be assigned contiguous channels if possible, but they can be any of the 10 from 3550-3650. (3650 up is all GAA, after incumbents are protected.) First they protect satellites, and those can go as low as 3600. Plus any radar, of course, when/where it pops up in the coastal zone. So if radar reduces the availability of channels, PAL can be shifted away and thus bump GAA.
Given how PALs work, a CBSD may be PAL in one census tract and GAA in another. A PPA goes down to the -96 dBm contour but only gets protection from noise above -80 dBm, so within its PPA it could have a -16 dBm SNR.
A PA licensee could even try putting on a lot of stuff GAA and then only invoke the PAL on sectors where it seems needed. Having one PAL could be handy for that reason, and in rural areas it might be affordable.
And to Josh's comment, I do still have about 30 license holders looking for a buyer. Contact me off list at [email protected] if interested.

We would be using it for a handful of backhauls to get off of crowded 5GHz space. However, I'm not sure if this is a smart move (buying a 3.65 license) and wanted some insight from those who have much more knowledge on where the FCC is going with this and what the likely value of a 3.65 license will be both today and next year (?) when the licenses are potentially opened back up. It looks like these licenses, at least in my area, are selling between $500 and $2000. It sounds like $1,000 tends to be about the sweet spot for the few that have sold around here.Existing 3.65 licenses all expire on the same date in 2020, *except* a few from late 2010- early 2013 that can expire as late as 2023. They allow you to add new radios under that license, but they are not protected (from other types of CBRS users) as "incumbent" under the now-operative Part 96 CBRS rules. Registration of devices that will qualify as "incumbent" closed in 2015. So you can operate new gear, but will have the same status as GAA (licensed-by-rule) users once CBRS gear has gone through the whole process to make the new band usable. There will be no Priority Access Licenses operating above 3.65; PAL is limited to 3.55 to 3.65. Of course 3.65 is still subject to satellite restrictions, if you're in one of the Protection Zones. Satellites are Incumbent, so on CBRS, they will get protection, and both GAA and PAL channels will be assigned around them. However, unlike today's 150km zones, CBRS will use the Spectrum Authorization System to compute the required protection. That will certainly mean less than 150 km. You can look in the FCC's ULS to see if anyone else is registered nearby. 3.65 is subject to a "sandbox clause", wherein users have to play nice with one another. It's unlikely that well-focused backhauls will run into a problem there, but you should know who's around.
