* @brief Default LoRaWAN channels
*
* @note It is possible to use a single channel, e.g., when using a single or
* dual channel gateway, by defining the macro `GNRC_LORAWAN_SINGLE_CHANNEL`
* during compilation, which specifies the single channel frequency to be used.
* For example:
* ```
* CFLAGS='-DGNRC_LORAWAN_SINGLE_CHANNEL=868100000UL'
* ```
