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.

The current health of the backbone is monitored here (internet)

Active Sites

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.

Cooperation

This link is provided in cooperation with Matt.

San Bruno Mountain

Fish Ranch / ORCA

Status: Equipment installed. Appears 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.

Plans

Current plans for a site visit in August 2022. The goal is to replace one of the AREDN nodes at the site (the NSM5) with a more powerful radio, as well as complete the work to bring up the link to Fish Ranch. We will also investigate adding a link to CCCC.

CCCC

Status: Proposed

Black Mountain

Status: Proposed

Fire Station 8

Status: Proposed

CCCC

General

Plans

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

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.

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.

San Bruno Mountain

Status: Proposed

Mount Diablo

Slides detailing the configuration can be found here and here.

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.

Needed Sites

East Bay

The most southerly backbone site is in the Oakland Hills. There is a need for a number of high sites stretching down the East Bay to Fremont and Milpitas.

Peninsula

The most southerly backbone site is San Bruno Mountain. There is a need for high sites stretching down though Burlington, Mountain View and Palo Alto.

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.
