BreezeNET B 162 System Manual
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.
4.2.6.5.11 Ethernet Frame Size
This option configures the maximum Ethernet fame size to either 1600 or 2000
bytes. The 2000 bytes maximal frame size will be enabled only if it is set as such
at both ends of the link. If one of the units (BU or RB) uses 1600 bytes frames, the
link will use 1600 bytes frames as well.
The available settings are:
 1600 Bytes
 2000 Bytes
The default is 1600 bytes.
4.2.6.5.12 Concatenation Parameters
The Concatenation mechanism enables bundling several data frames into a single
frame for transmission to the wireless link. This feature improves throughput and
reduces the overhead in the wireless medium, by reducing the overhead
associated with each transmission. When concatenation is enabled, data packets
in the queue of the internal bridge can be accumulated before the concatenated
frame is transmitted to the wireless medium. Data frames can be concatenated up
to a maximum frame size of 2200 bytes for BU/RB-B14 and BU/RB-B28 units,
and 4032 bytes for BU/RB-B10 and BU/RB-B100 units.
A frame is a candidate for bundling into a concatenated frame if all the following
conditions are met:
 The frame is a data frame
 The destination is an entity behind the destination BU/RB.
 The destination unit can support the feature (uses SW version 3.0 or higher).
NOTE
If the destination unit uses SW version 3.0 (learned during the Link Capability exchange process),
the maximum number of data frames that can be concatenated is limited to two. If the destination
unit uses SW version 3.1, the maximum number of data frames that can be concatenated is limited
to eight.
