Site Details

Proposal

The following installation at Sunol Ridge is being evaluated (as of 17th, Dec 2022):

• A point-to-point backbone link connecting the site to San Carlos.
• A 120° sector running AREDN pointing towards Livermore.
• A 120° sector running AREDN pointing towards Fremont.
• A PoE switch and hAP AC2 to power and manage the installation.
• Battery backup in case of power loss.

Configuration

Sunol Ridge hosts an Edge Router X SFP and an EdgePower 24V 72W, an airFiber 5XHD, a hAP AC2 and various other AREDN nodes.

Power

Power is provided on site. A backup generator is also included. However, we include our own backup power using an EdgePower 24V 72W and two 24Ah LiFePO4 batteries. The batteries are mounted on a 2U shelf mounted towards the bottom of the equipment rack and provide ~1 day of backup power. The rack already contains other batteries for separate equipment so this is compromise between space, weight, and runtime.

Commercial Neighbors

Etheric Networks, Inc. shared tenancy at Sunol Ridge. They license (WQUA557 WRJT283) spectrum in the 5.96 GHz (60 MHz), 6.09 GHz (30 MHz), 6.21 GHz (60 MHz) and 10.8 GHz range. Unlike many microwave tenants, the licensed band overlaps with the WiFi 6E spectrum which must defer to their use. Care must be taken when running a backbone link through this site, although we are unlikely to be run links in similar directions.
