1. The Frequency coding is identical to the NewChannelReq MAC command defined in the
2. Class A.
3. Frequency is a 24bits unsigned integer. The actual beacon channel frequency in Hz is 100
4. x frequ. This allows defining the beacon channel anywhere between 100 MHz to 1.67 GHz
5. by 100 Hz step. The end-device has to check that the frequency is actually allowed by its
6. radio hardware and return an error otherwise.
7. A valid non-zero Frequency will force the device to listen to the beacon on a fixed frequency
8. channel even if the default behavior specifies a frequency hopping beacon (i.e US ISM
9. band).
10. A value of 0 instructs the end-device to use the default beacon frequency plan as defined in

25 the ―Beacon physical layer‖ section. Where applicable the device resumes frequency
