and 1064), enabling to select the DFS detection algorithm if DFS should be
enabled.
The available options are ETSI and FCC.
The default is ETSI.
4.2.6.2.5.4 Show Frequency Definitions
Upon selecting the Show Frequency Definitions, the selected frequencies in each
of the available Sub Bands and the current operating frequency will be displayed.
4.2.6.2.6 Best BU Parameters (RB)
In certain applications multiple BUs may be used to provide redundancy for high
availability. An RB that can communicate with more than one BU using the same
ESSID may become associated with the first BU it "finds", not necessarily the best
choice in terms of quality of communication.
The need to create best throughput conditions for the RB led to the creation of the
Best BU feature, to enable an RB to connect to the best BU in its neighborhood.
When the Best BU feature is used, each of the BUs is given a quality mark based
on the level at which it is received by the RB. The RB scans for a configured
number of cycles, gathering information from all the BUs with which it can
communicate. At the end of the scanning period, the RB reaches a Best BU
decision according to the information gathered. The BU with the highest quality
mark is selected as the Best BU, and the RB will immediately attempt to associate
with it. The quality mark given to each BU depends on the level at which it is
received by the RB.
The Best BU selection mechanism can be overridden by defining a specific BU as
the preferred BU.
The Best BU Parameters menu includes the following options:
4.2.6.2.6.1 Best BU Support
The Best BU Support option enables or disables the Best BU selection feature.
The default is Disable.
4.2.6.2.6.2 Number Of Scanning Attempts
When the Best BU option is enabled, the RB gathers information on neighboring
free BUs for approximately 2 seconds on each of the scanned frequencies. The
NOTE
If the Best BU feature is not used, the RB associates with the first free BU it finds whose ESSID or
Operator ESSID is identical to its own ESSID.
