Objective

This task will establish the Pilot installation in Africa

  • solar-cell driven Wifi access point
  • link to "tower" containing local content
  • installation report
Category:Task


Deliverables in T1.2 Pilot installation Kjeller

Add Deliverable


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. 90 deg sector antenna for Wifi distribution

Health spot installations

[[File:Health_spot_installation.png|250px|right|Health Spot at Kjeller - with good help from Øyvind and Maghsoud]

  • 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

Charge indicator despite the light rain
  • 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
