Deliverables in T1.2 Pilot installation Kjeller
Expected outcome
Year 1:
- Pilot installation (M06)
- Suggestion for installation (M08)
Pilot installation at Kjeller
Infrastructure
The pilot at Kjeller involves the equipment at the health spot and the communication equipment at the tower.
Health spot installations
- 2 Solar panels (53 x 35 cm each, max 6W (350 mA max), Biltema 31631= 2 x 389 NOK)
- 1 controller (Biltema 31635 - 189 NOK)
- 1 Battery 12V 18AH (Biltema 80413 - 499 NOK)
- Cables and connectors (Clas Ohlson 36-3902- 69 NOK)
- USB connector (Clas Ohlson 38-7050 349 NOK )
- (not used: PoE injector, ~90 NOK)
- Receive antenna with local beam (Witelcom)
The total costs are 1900 NOK, roughly 210 € (+Witelcom receive antenna + construction work + box )
- Light: (LED-spotlight? 36-5024 199 kr) - or Campinglampe 24955 89,90 kr)
- needed: splitter for 2 solar panels
Communication equipment
- 90 deg sector antenna (Witelcom)
- Mikrotik router board RG 1100Ah (ca 400 €) - alternative? - need to consider power consumption and the robustness. Other Mikrotik devices?
Experiences from pilot installation
- The power consumption from the wireless link is roughly 200-250 mA
- Each solar panels deliver in cloudy conditions roughly 110 mA
- Thus, two panels delivering 220 mA (in cloudy conditions, even light rain) is sufficient for operation
- Antenna pointing was not a problem, but we had a challenge in configurability
