Why region matters
A device configured for the wrong regional frequency plan may not communicate with the network. Gateways and devices must support the same band, such as EU868, US915, AU915, AS923, IN865, KR920, or another local plan.
Regional parameters also affect channels, transmit power, receive windows, maximum payload size, and sometimes duty-cycle or listen-before-talk behavior.
Treat the frequency plan as part of provisioning. Device model, firmware region, gateway channel plan, network server configuration, and local radio rules all need to match.
Duty cycle in plain language
Duty cycle limits how long a device can occupy a channel over time. It prevents one device from talking too often and making the shared radio spectrum unusable for everyone else.
For beginners, the practical rule is simple: keep LoRaWAN payloads small, avoid unnecessary confirmed messages, and do not send too frequently.
