BreezeACCESS Version 4.3 Operations and Administration
Manual Revision: 4.0
its MAC address, it will associate with it and terminate the
scanning process. If the preferred AU is not found, the SU will
associate with an AU according to the decision reached using
the best AU algorithm.
Valid values: MAC address string
The default value for the Preferred AU MAC Address is
00-00-00-00-00-00 (12 zeros), meaning that there is no
preferred AU.
 Show Best AU Parameters and Data – Displays the applicable
information:
 Neighboring AU Data table - Displayed for each AU that the
unit can communicate with the following parameters:
 MAC Address
 Received signal strength – RSSI or dBm
 Mark – The computed quality mark for the AU.
 Full – The association load status of the AU. It is defined
as full if the number of SUs associated with the AU has
reached the maximum allowed according to the value of
the Maximum Number of Associations parameter (see
page 2-62). An AU whose associations load status is full
cannot be selected as the Best AU, even if its’ computed
mark is the highest.
 ESSID – The ESSID of the AU
In addition to the neighboring AU data table, the following
information is displayed:
 Best AU Support
 Preferred AU MAC Address
 Number of Scanning Attempts
 Associated AU MAC Address (the MAC address of the
selected AU)
 Run Time ESSID (the ESSID of the selected AU).
Power Control Parameters
The power control parameters enable to optimize the performance of the
system through controlling the transmitted power level of
BreezeACCESS units. The transmitted power level of the unit should be
decreased from the maximum level that is supported by the unit in the
following cases:
 In a Subscriber Unit that is relatively close to the Access Unit, in
order to minimize the interference to signals received by the AU from
other subscriber units as well as interference to neighboring cells.
 In an Access Unit typically the maximum supported transmit power
is used to enable maximum coverage. However, there may be a need
to decrease the transmitted power level in order to support relatively
small cells and to minimize the interference with the operation of
neighboring cells.
