Alvarion SW VERSION 5.1 system manual Number of HW Retries, Burst Mode Option

Menus and Parameters

Available values: -1 to 32. -1 is for no weight for history, meaning that average SNR equals the last measured SNR.

Default value: 5

4.2.6.5.6Number 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 4.2.6.5.8.

NOTE

The Number of HW Retries parameter is not applicable when the Wireless Link Prioritization Option is enabled.

The available values range is from 1 to 14.

The default value is 10.

4.2.6.5.7Burst Mode

Burst mode provides an increased throughput by reducing the overhead associated with transmissions in the wireless medium. In a burst transmission the inter-frame spacing is reduced and unicast data frames are transmitted without any contention period (burst mode is not activated on broadcasts/multicasts).

The Burst Mode is available only if Burst Mode is supported by the Sub-Band in use. For information on how to view the Sub-Bands supported by the unit and the supported parameters’ values and options, refer to section 4.2.2.4.

In AUs with HW Revision B or lower, Burst Mode cannot be activated when DFS is used. In AUs with HW Revision B or lower, the Burst Mode option will be “blocked” upon trying to enable Burst Mode when DFS is enabled. This limitation does not apply to AUs with HW Revision C.

In SUs and AUs with HW Revision B or lower, Burst Mode cannot be activated when using WEP for data encryption. In units with HW Revision B or lower, the Burst Mode option will be “blocked” upon trying to enable it when using WEP for data encryption. This limitation does not apply to units with HW Revision C.

NOTE

The Burst Mode parameters are not applicable when the Wireless Link Prioritization Option is enabled.

4.2.6.5.7.1 Burst Mode Option

The Burst Mode Option enables or disables the Burst Mode operation.
