 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
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 received data frames. This average SNR is used by the ATPC algorithm in
the BU and is also included in the Adaptive Modulation algorithm information
messages transmitted by the BU and the RB. 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 4.2.6.5.9.
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
