The available options are:

Basic Rate - Sets 3 modulation thresholds for the sent ACK frames depending
on the modulation of the received frame:

Modulation Level 1 - Sends all ACK frames in modulation 1.
The default setting is Basic Rate.
4.2.6.5.7 Average SNR Memory Factor
This parameter is not supported in the current release. The Average SNR Memory
Factor defines the weight of history (value of last calculated average SNR) in the
formula used for calculating the current average SNR for data frames received
from SUs. This average SNR is used by the ATPC algorithm in the AU and is also
included in the Adaptive Modulation Algorithm information messages transmitted
by the AU and the SU. The higher the value of this parameter, the higher is the
weight of history in the formula.
Available values: -1 to 32. -1 is for no weight for history, meaning that average
SNR equals the last measured SNR.
Default value: 5.
4.2.6.5.8 Number of HW Retries
The Number of HW Retries parameter defines the maximum number of times that
an unacknowledged packet is retransmitted. When the Adaptive Modulation
Algorithm is disabled, a frame will be dropped when the number of unsuccessful
retransmissions reaches this value. For details on the effect of this parameter
when the Adaptive Modulation Algorithm is enabled, refer to
Section 4.2.6.5.10 .
The available values range is from 1 to 14.
The default value is 10.
4.2.6.5.9 Burst Mode
Burst mode provides an increased throughput by reducing the overhead
associated with transmissions in the wireless medium. In a burst transmission
