I wondered if there is some consensus on practical options to implement the Capital Park-Beacon Link? I've tried to sum these up into bins/options based on the thread info and what I'm aware of. Is this about right, or are there other combinations? Do any of these fit/make sense more than others? Option A: We put 24 GHz between Seattle EOC<-->Beacon, and then use the 5.8 GHz intended for the EOC link as dedicated Beacon<-->Capital Park link. (ie: a pair of UBNT Airfiber 24 radios) Option B: We continue with the Seattle EOC<-->Beacon link as currently designed, and plan a new 3 GHz UBNT link between Capital Park and Beacon. *This might screw up Bart's announced plan for a 3 Ghz Link Beacon to Haystack. Option C: We continue with the Seattle EOC<-->Beacon link as currently designed, we help Bart implement the 3GHz link Beacon to Haystack, and then re-use the current 5 GHz Beacon dish (pointing at Haystack) as a new Capital Park<--> Beacon link. (assuming we have enough 5 GHz spectrum to do that) Option D: We continue with the Seattle EOC<-->Beacon link as currently designed, and use 10 GHz Mimosa link between Capital Park and Beacon. ($$, but maybe. I think it's too far for 24 GHz.) Option E: UBNT AF24 Seattle EOC<-->Beacon, AND Mimosa 10GHz Beacon Tower<-->Capital Park *Assumes we win the lottery or otherwise find $8,000. Probably not practical, but we'd have a hack of a fast backbone and demonstrate use on 10 and 24 GHz ham bands. Best, Randy On Thu, Mar 29, 2018 at 4:38 PM, Doug Kingston <dpk@randomnotes.org> wrote:
So I like the concept in principle of connecting Capitol Park to Beacon in part to create a core of sector connectivity that is easy to maintain. I agree that 750 and end is steep for us. What other options do we have? For example... Can we reuse a PtoP 5GHz frequency with high isolation (shielding)?

Thanks Brian, I was looking at the FCC table - You're right, 3550 not 3450.

Citizens Broadband Radio Service just took away 3450-3500 from the Amateur band.
Do you have a source on this? I saw CBRS opened up 3550 to 3650 and 3650 to 3700 is the old part 90 WISP band.
3400 to 3500 is shared with mil radar, and I didn't see the USAF vacating this band.
