This figure depicts the Zigbee network as a long horizontal rectangle divided into segments. The first segment (moving left to right) is a small light blue segment labeled "Beacon." The second segment is a longer gray segment labeled "Contention slots." This segment is further divided into eight time slots. The next segment is also a longer gray segment, labeled "Guaranteed slots." This segment, too, is divided into eight time slots. The next segment is a light blue segment of indeterminate length, labeled "Inactive period." And the last segment is a small light blue segment that is unlabeled but looks identical to the beacon segment. The frame itself, from the beacon to the end of the inactive period, is labeled "Super frame."
