Detailed Description

This class supports LorawanMac instances by managing a list of the logical channels that the device is supposed to be using, and establishes their relationship with LoraSubBands.

This class also takes into account duty cycle limitations, by updating a list of LoraSubBand objects and providing methods to query whether transmission on a set channel is admissible or not.
