Chapter 4 - Operation and Administration
4.2.6.5.10.3.4RTS Duration Mode
If the RTS mechanism is enabled, when attempting to retransmit frames on lower
modulations, the RTS employed may be adjusted so that it pertains to either the
initial transmission modulation or the lower retransmission modulation. The
available options are:
Short RTS Duration: Retransmission attempts on lower modulations use the
RTS duration that applies to the initial transmission modulation.
Long RTS Duration: Retransmission attempts on lower modulations use the
RTS duration that applies to the corresponding lower retransmission
modulation.
The default value is Short RTS Duration.
4.2.6.5.10.4 Adaptive Modulation Parameters
This submenu configures parameters for the basic Adaptive Modulation
algorithm. When enabled, the algorithm supports decrease/increase of
transmission's modulation levels between the lowest possible level to the value
configured for the Maximum Modulation Level parameter. If the Maximum
Modulation Level is set at the lowest possible level, the Adaptive Modulation
algorithm has no effect.
4.2.6.5.10.4.1Minimum Interval Between Adaptive Modulation Messages
The Minimum Interval Between Adaptive Modulation Messages sets the minimum
interval between two consecutive adaptive modulation messages, carrying
information on the SNR of received signals. The messages in the AU include SNR
information on all the SUs associated with it.
The available range is from 1 to 3600 seconds.
The default is 4 seconds.
4.2.6.5.10.4.2Adaptive Modulation Decision Thresholds
Enables selection between Normal and High decision thresholds for the Adaptive
Modulation algorithm. In links with a low SNR (below 13), the Adaptive
Modulation algorithm may not stabilize on the correct modulation level when
using the standard decision thresholds. In this case the algorithm may try to use
a modulation level that is too high, resulting in a relatively large number of
dropped frames. The "High" option solves this limitation and ensures good
performance also in links with a low SNR.
The default is Normal.
