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.
