DigI:TI1.2

= Expected outcome = Year 1:
 * has result::Pilot installation (M06)
 * has result::Suggestion for installation (M08)

= Pilot installation at Kjeller = The pilot installation at Kjeller is the integration test for WP-T1 Specs Tanzania and WP-C1 Specs Congo. Example of the Health Spot information is given at http://digi.futurecompetence.net/

Infrastructure
The pilot at Kjeller involves the equipment at the health spot and the communication equipment at the tower.

Health spot installations

 * 1 IBC Solar module SoloSol 100 CS 100W
 * 1 Regulator m/display SC-D10A/1224
 * 1 Battery 12V 22AH (Biltema - 649 NOK)
 * Cables and connectors (Clas Ohlson 36-3902- 69 NOK)
 * USB connector (Clas Ohlson 38-7050 349 NOK )
 * 1 LED lamp 5W
 * (not used: PoE injector, ~90 NOK)
 * Receive antenna with local beam (Witelcom)

The update was necessary as the previously used controller had a two small hysteresis, ending up in a "jitter" on the power on/off, which turned down the hot-spot. After having updated to the bigger installation, we received stable conditions. Earlier installation:
 * 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)

The total costs are 1900 NOK, roughly 210 € (+Witelcom receive antenna + construction work)


 * Light: (LED-spotlight? 36-5024 199 kr) - or Campinglampe 24955 89,90 kr)
 * needed: splitter for 2 solar panels

Tower installation

 * Mikrotik box (RB960PGS-PB or others) -
 * function: connect to village server, divide traffic between free/local, InfoInternet and Voucher traffic
 * alternatively: install RB on village server, and perform "soft routing"
 * power consumption: 9 W, with PoE
 * 90deg sector antenna, 20 W(?)
 * backend connectivity
 * Village server
 * as USB dongle(?)
 * as ownstanding server (?)

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?
 * Alternative: RB960-PGS-PB, max 9W (but about 25% performance of RG 1100 AH)

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

Witelcom connectivity
 * SW allowing for DHCP relaying (switch off local DHCP provision)
 * (failure (20May2017): reset into old SSID mode)
 * default administrator - can't change admin username
