This is an initial plan for what is needed for a Tier 1 site. Tier 1 sites provide the backbone data ring they are assumed to only have tier 2 sites connected to them. These sites should remain running without grid power for a minimum for 48hours running at 100% duty cycle.

Provisional planning for each tier 1 sites is as follows:

3x PTP radios

1x 10port Ethernet Switch (5 port gigE, 5 port FE)

1x BeagleBone/Rasberry Pi

1x UHF Data Radio

1x VHF Data Radio

1x Battery System

1x Charging System

Core equipment takes 8-30V input voltage, to minimize line losses for POE, we have standardized on 24V main bus, with DC-DC converters providing 12 and 5V out for other equipment.

To provide 48Hours of off grid operation, a battery system providing 240Ah@24V at 80% DOD is needed.
