Detailed Description

The IEEE 802.15.4 frame has a number of constant/fixed fields that can be counted to make frame construction and max payload calculations easier.

These include: 1. FCF - 2 bytes - Fixed 2. Sequence number - 1 byte - Fixed 3. Addressing fields - 4 - 20 bytes - Variable 4. Aux security header - 0 - 14 bytes - Variable 5. CRC - 2 bytes - Fixed Defines the bitfields of the frame control field (FCF).
