 Associated BU MAC Address (the MAC address of the selected BU)
4.2.6.2.7 Scanning Mode (RB only)
The Scanning Mode parameter defines whether the RB will use Passive or Active
scanning when searching for a BU.
In passive scanning, the RB "listens" to the wireless media for approximately two
seconds at each frequency, searching for beacons. The disassociation period,
which is the time from the moment the link was lost until the RB decides that it
should start searching for another BU, is approximately seven seconds.
In some situations when there is a high probability that RB might need to roam
among different BUs, the use of active scanning enables to significantly reduce
the link establishment time. This is achieved by using shorter dwell periods,
transmitting a Probe Request at each frequency. This reduces the time spent at
each frequency as well as the disassociation period.
When DFS is supported by the Country Code being used by the RB, Scanning
Mode is forced to Passive.
The default selection is Passive.
4.2.6.2.8 Power Control Parameters
The Automatic Transmit Power Control (ATPC) algorithm simplifies the
installation process and ensures optimal performance while minimizing
interference to other units. This is achieved by automatically adjusting the power
level transmitted by the RB according to the actual level at which it is received by
the BU. To support proper operation of the system with optimal performance and
minimum interference between neighboring systems, the ATPC algorithm should
be enabled in both BU and RB.
The algorithm is controlled by the BU that calculates for each received frame the
average SNR at which it receives transmissions from the RB. The average
calculation takes into account the previous calculated average, thus reducing the
