This is an initial plan for what is needed for a Tier 2 site. Tier 2 sites provide the Access Points into the data ring. Tier 2 sites contain sectors similar to a cellular tower network. These sites should remain running without grid power for a minimum for 24hours running at 100% duty cycle.
Provisional planning for each tier 1 sites is as follows:
1x PTP radios
3x PMP radios
1x 5port Ethernet Switch (1 port gigE, 4 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 24Hours of off grid operation, a battery system providing 150Ah@24V at 80% DOD is needed.
