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.
Key assumptions check
| Nr | Assumption | Caveation | Usages |
|---|---|---|---|
| 1 | Price is a limiting factor. | Partially caveated | |
| 2 | The price of NB-IoT is lower due to lower bit rate | Not caveated |
Assessment
| Nr | Fact | Comment | Assumption | Assessment | Conclusion |
|---|---|---|---|---|---|
| 1 | The range of the LoRa gateway will be dependent on positioning, line of sight, antenna performance and bitrate. | There are no LoRa units in the vicinity of Ålesund. | It is likely that the LoRa device will have an estimated range of 7 kilometers. This means that there has to be a LoRa device within 7 kilometers for each measuring device.

| Telia network is stationary and widespread. | The price of NB-IoT is lower due to lower bit rate. | The NB-IoT is highly likely the better choice from Telia. Telia NB-IoT is likely more reliable than LoRa. | Row: 1, 2 Answers to: PIR 1, SIR 1.1, SIR 1.2 Conclusion: NB-IoT seems to be the general better solution due to reliability. LoRa could however be a good decision if the range is sufficient. |
