7.3.4 LoRa Radio Card (US)
Gateways that operate in the US region should have a 500-kHz channel. In Figure 26 , the allowed placement
of these channels displays larger and blue.
If a 500-kHz channel is not configured, the interface displays a warning.

7.3.5 LoRa Radio Card (EU)
There are three mandatory channels for gateways that operate in the EU region. These channels are 868.1,
868.3, and 868.5.
The EU region bands have different duty cycles. This is indicated with a grey background box and label in
Figure 27 . A higher duty cycle allows higher throughput.
The EU region specifies keep out areas in the allowed frequencies. These are highlighted in red on the
illustration. The interface displays a warning if a channel lies in a keep-out area.
