When a frame is identified as an eligible candidate for concatenation, it is marked
accordingly and will be processed according to the following:
If there is no concatenated frame designated to the same destination unit in
the queue:
» If the hardware queue is empty - the frame is transmitted immediately.
» Otherwise (the queue is not empty) - the frame is inserted to the queue as a
concatenated frame.
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).
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).
Concatenation Option The Concatenation Option enables or disables the concatenation
mechanism.
Maximum Concatenated
Frame Size (bytes)
The Maximum Concatenated Frame Size parameter defines the
maximum size (in bytes) for a concatenated frame.
The range is:
256 to 2200 bytes for BreezeACCESS units with HW revision A or
B and BreezeNET B B-14/28 units
256 to 4032 bytes for BreezeACCESS units with HW revision C or
higher and BreezeNET B B-10/100 units
