b. If first transmission trial has failed, the frame will be
retransmitted at the same rate up to the maximum number of
retransmission attempts defined by the Number of HW Retries
parameter.
c. If the frame was not acknowledged and the Software Retry
Support option is disabled, the frame will be dropped. If the
Software Retry Option is enabled, the frame will be moved to the
end of the queue. All other frames in the queue that are intended
to the same destination will be moved as well, to preserve the
original order. This process is referred to as a Software Retry.
d. The frame will be retransmitted at the rate selected by the
algorithm for the new retrials sequence. Each retrial sequence
comprises a number of attempts defined by the Number of HW
Retries.
e. The process will be repeated up to a maximum number of
Software Retries defined by the Number of SW Retries parameter.
The Multi-Rate Parameters menu includes the following parameters:
Multi-Rate Support
The Multi Rate Support option enables or disables the Multi-Rate decision
algorithm. When enabled, the algorithm supports decrease/increase of
transmission rates between the lowest possible data rate which is 6 Mbps
to the current value of the Maximum Data Rate parameter. If the
Maximum Data Rate is set at 6 Mbps which is the lowest possible data
rate, the Multi Rate Support has no effect.
The default selection is Enable.
Software Retry Support
The Software Retry Support option enables or disables the software retry
mechanism in the Multi Rate algorithm. When enabled, the algorithm
supports decrease/increase of transmission rates between the lowest
possible data rate which is 6 Mbps to the current value of the Maximum
Data Rate parameter. If the Maximum Data Rate is set at 6 Mbps which is
the lowest possible data rate, the Multi Rate Support has no effect.
The default selection is Enable.
Number of SW Retries
The Number of SW Retries parameter enables defines maximum number of
times to use the software retrial mechanism when the Software Retry
Support option is enabled.
