WLAN
Below is an example of how sequence and fragment number incrementation works within the PathWave Signal Generation for WLAN application. In this example, a 12-frame transmission with three sequences of four frames each will be set up.
Configure the parameters as shown below:
This configuration will cause the Sequence Control field of the MAC header to act as shown below:
Notice that the sequence number increments and the fragment number wraps to zero every four frames.
If you set the to OFF for this example, the sequence number will not increment, and the fragment number will increment to B hex (11 decimal). If you set to OFF and the number of frames is greater than 16, the fragment number will increment to F hex (15 decimal) and wrap to zero.
You can set the initial sequence and fragment numbers by editing the Sequence Control setting of the MAC header. The sequence number can be set from zero to its upper limit of FFF hex (4095 decimal). The fragment number can be set from zero to its upper limit of F hex (15 decimal). The sequence and fragment numbers always wrap to zero, regardless of the initial settings.
