rate at which multicast packets are sent, should be
configured in such a way that the multicasts can be
received by all subscribers located in the wireless cell. The
data rate for multicasts is set to a fixed value and therefore
depends on the properties of the wireless cell and its
clients. In the case of very small cells with clients whose
radios support at least 11 Mbps, it can be set to Fixed 11
Mbps. In the case of large cells or cells with older clients
which support merely 1 or 2 Mbps, a slower rate of Fixed 1
Mbps or Fixed 2 Mbps is recommended.
• RTS Threshold
This setting is only relevant if the BAT 11b-AC is to be
operated in ad-hoc mode. RTS means Request To Send and
is the threshold value from which on an RTS signal will be
sent into the wireless cell. For this value, the default
setting 2347 should be used. You should use slightly
minor values only if an irregular data flow is observed. The
smaller the value, the more bandwidth will be lost for RTS
signals. As a result, the data rate of the wireless cell will
decrease.
• Load Balancing
This setting refers to wireless networks with several
access points. Per default, load balancing is active. In this
case, the beacons of the access point transmit information
on the logged-on clients and the cell utilization of the
access point in regular intervals. A client can compare this
information to the load balancing information of other
access points within reach and decide independently
whether roaming to a weaker access point with less data
traffic makes sense.
• Microwave Robustness
In environments with strong interferences caused by other
devices using the 2.4 GHz band, the data rate may be
affected. Although the activation of microwave robustness
reduces the net throughput in an interference-free
environment, it may increase the throughput in an
