LoRaWAN

LoRa long-range communication system, similier to WIFI but working over very long distances (up to 10km). Unlike regular wifi, LoRa is designed to send only very small amounts of data, and pretty slowly.

LoRaWAN defines the communication protocol and system architecture for network based on LoRa.

The Things Network is a global collaborative Internet of Things ecosystem that creates networks, devices and solutions using LoRaWAN.

Setting up the MKR WAN 1310 on The Things Network

Visualising Data on The Things Network

Data is stored on The Things Network for up to 7 days. The data can be exported, and it’s possible to integrate with many IOT platforms for handling live data streams.

API Reference

Terms:

OTAA: OTAA end devices are assigned a new DevAddr at establishing each new session. This allows them to move to different networks/clusters.

ABP: ABP end devices use a fixed DevAdd

AppEUI and JoinEUI are the same things
