 If a concatenated frame designated to the same destination unit exists in the
queue:
» If the combined size of both frames is above the maximum allowed
concatenated frame size - both frames are transmitted as two separate
frames.
» Otherwise (the combined frames size is below the maximum size) - the new
frame is added to the concatenated frame. If the number of data frames in
the concatenated frame has reached the maximum allowed (applicable only
if the destination unit uses SW version 3.0 or 3.1) - the concatenated frame
will be transmitted to the wireless medium. Otherwise - the concatenated
frame remains in the queue (until the hardware queue becomes free).
The Concatenation Parameters submenu includes:
4.2.6.5.11.1 Concatenation Option
The Concatenation Option enables or disables the concatenation mechanism.
The default is Enable.
4.2.6.5.11.2 Maximum Concatenated Frame Size
The Maximum Concatenated Frame Size parameter defines the maximum size (in
bytes) for a concatenated frame.
The range is:
 256 to 2200 bytes for units with HW revision A or B
 256 to 4032 bytes for units with HW revision C or higher
The Default values are:
 2200 for units with HW revision A or B
4032 for units with HW revision C or higher
NOTE
When a frame is marked as a candidate for concatenation, it will be transmitted as a concatenated
frame. If it is not bundled with another data frame before transmission, it will be a concatenated
frame with a single data frame (Concatenated Frame Single). If it is bundled with two or more data
frames, it will be a concatenated frame with either double data frames (Concatenated Frame
Double) or more data frames (Concatenated Frame More).
