The sequence control field in the 802.11 data frame indicates how packets will be subdivided for fragmentation. This field includes a fragmentation sequence number and a duration ID, which together indicate how the packet should be split into smaller fragments. The preamble header is used for synchronization and the frame check sequence is a checksum for error detection. The duration field in the data frame does not determine how packets are divided, but rather specifies how long the transmitting station will use the medium for the transmission of the entire packet.
