Knowledge

LoRaWAN explained: how the network works, which frequencies apply, what RSSI and SNR mean and how to plan coverage.

  1. LoRa and LoRaWAN What the two terms stand for, what LoRaWAN is made for and how a network is built.
  2. Joining and security OTAA and ABP, the keys of a device and why a gateway cannot read your data.
  3. Frequencies in Europe and Switzerland The EU868 band, its sub-bands, the duty cycle and the channel plan of The Things Network.
  4. Spreading factor, data rate and airtime Why SF12 reaches further than SF7, what that costs in airtime and when ADR fits.
  5. The Things Network The open community network, its fair use policy, gateways and integrations.
  6. Understanding the readings RSSI, SNR, packet loss, number of gateways and distance, and how to read them together.
  7. What determines range Line of sight, height, Fresnel zone, buildings and antenna, and why a measurement on site counts.
  8. Troubleshooting: the tester shows no values Five questions in order, from the battery to the webhook.
  9. Glossary The terms around LoRaWAN, briefly explained.
