Introduction:
LoRaWANTM | RadioShuttle |
Concentrator required | No concentrator required, the station uses regular LoRa module |
Network subscription fees (If use MQTT server) | No monthly fees |
One large radio cell | Many small independent radio cells |
Busy network in a radiu of many kilometers | Small networks with no interference |
Single point of failure (Concentrator) | Automatic transmitting power adjustment – longer battery life |
High latency, larger spreading factor, e.g. SF11 (1320 ms) | Low latency, small spreading factor, e.g. SF7 (120 ms) |
