Information requiremens:
LoRa
For a LoRa unit to connect to the internet it requires a gateway. The closest gateway to Ålesund is currently in Molde.
The price of a new gateway would probably be in the vicinity of 1100 kr. The range of the LoRa gateway will be dependent on positioning, line of sight, antenna performance and bitrate.
