'''Notes:''' The connection to Fish Ranch is somewhat influx due to access to San Bruno Mtn. The state of the installation needs to be improved with some changes to the onwards radios (there's a NSM5 there right now which doesn't really do the job). The best information is that the radio pointing at Fish Ranch is installed and requires adjustments. It may not currently be power and/or not connected to the other AREDN nodes at the site which are powered.
 +
'''Notes:''' The connection to Fish Ranch appears active, as Fish Ranch indicates an active link on the radio. This would suggest that the San Bruno end is correctly pointed and powered, but not yet connected to the rest of the AREDN network.

Backbone Map.png

The Bay Area Backbone Project is building solid, fast, links between major high sites in the Bay Area, which in turn supports a more stable mesh network. Backbone sites are permanent locations, not dependent on amateur radio operators' homes or difficult to access places.

Fish Ranch / ORCA

San Bruno Mountain

Status: Equipment installed. Powered. Link active to San Bruno.

Connection: Non-AREDN, airFiber 5 GHz.

Notes: Dish has been checked and is power, and shows a four bar, active link status to San Bruno (re: site visit 22nd, July 2022). However the device does not connect to the UISP tool because the WAN connection to Matt Peterson's is not currently connected, Matt believes is is unplugged at his end.

San Bruno Mountain

Fish Ranch / ORCA

Status: Equipment installed. Appear powered.

Connection: airFiber 5 GHz.

Notes: The connection to Fish Ranch appears active, as Fish Ranch indicates an active link on the radio. This would suggest that the San Bruno end is correctly pointed and powered, but not yet connected to the rest of the AREDN network.

Black Mountain

Status: Proposed

Fire Station 8

Status: Proposed

CCCC

Mount Diablo

Status: Equipment installed. Active.

Connection: Non-AREDN, airFiber 3 GHz. Acts as DtD.

Notes: Connects via DtD over non-AREDN radios, so appears as wired AREDN connection, even though it isn't.

Plans: Re-evaluate the battery system and determine why it fails to provide the constant power required for all the equipment.

Richmond Field Station

Status: Equipment installed, Active.

Connection: Non-Ham, 5 Ghz AC gen2, unknown equipment.

Notes: Connects via DtD over non-AREDN radios, so appears as a wires AREDN connection, even though it isn't.

Mount Diablo

CCCC

Status: Equipment installed. Active.

Connection: Non-AREDN, airFiber 3 GHz.

Note: Connects via DtD over non-AREDN radio.

Richmond Field Station (RFS)

CCCC

Status: Equipment installed, Active.

Connection: Non-AREDN, 5 Ghz AC gen2, unknown equipment.

Notes: Connects via DtD over non-AREDN radio.

Black Mountain

San Bruno Mountain

Status: Proposed

Fire Station 8

San Bruno Mountain

Status: Proposed

Notes

DtD connected nodes

The backbone is currently being constructed using Part 15 devices acting as bridges between AREDN nodes. The AREDN nodes connect to bridges via the DtD port / VLAN 2. This essentially puts every node at every location in the Backbone on the same VLAN. Consequently, every broadcast from any node connected directly to any Backbone point will have its traffic retransmitted to every other node. This probably isn't a good thing. Additionally, today the Backbone is a tree (disconnected in place) at the moment, but one day might become a loop or a graph. This would improve redundancy. However, at that point we're introducing loops into out VLAN where broadcast traffic could cycle around continually causing a storm.

It probably makes more sense to reconfigure the Part 15 devices as the AREDN "WAN" (not really the Internet in this case) and create explicit tunnel between specific AREDN endpoints. This is similar to how the Southern California Mesh does it.
