Satellite provision

We have two basic forms for distribution of the Basic Internet

i) Satellite Modem includes Router Board
e) Satellite Modem has an exteral Router Board

The Router Boards are preconfigured with an IP address, and thus only need to be connected to the satellite to be connected automatically to the billing centre at Kjeller.

Si5 configuration

Configuration Si1, converting the satellite link into a local Wifi link

The Si1 configuration includes

  • a satellite dish (1.2 or 1.8 m diameter)
  • a satellite modem including the router board, e.g. xxx
  • a wifi unit, transmitting the 2.4 GHz, e.g. xxx

The receive antenna can typically be set up on the ground, at a wall or whatever other place is suitable.

Si5 configuration

Configuration Si5, converting the satellite link into a local distribution to 5 or more customer equipments

The Si5 configuration includes

  • a satellite dish
  • a satellite modem including the router board, e.g. xxx
  • a distribution network, consisting of directional links from a main antenna to smaller antennas at the customer site. The link is typically operating at 5 GHz, e.g. xxx
  • a wifi unit, transmitting the 2.4 GHz, e.g. xxx

In the Si5 configuration we need to ensure free sight (no obstacles, no trees) between the main distribution antenna and the antennas at the customer site. This might require mounting the 5 GHz distribution networks on poles. Typical maximum ranges are 5-8 km for each of the distribution links.

Si20 configuration

same as Si20, but with 4 x 90 deg antennas for distribution to a total of 20 or more customer receive stations covering the whole area.
