Performance - Alvarion BreezeNET PRO.11 Series User Manual

3.5.2 Performance

The Performance menu determines the unit performance:
Dwell Time (AP Only) – The time spent on a radio channel before hopping to
the next channel in the sequence.
RTS Threshold – Minimum packet size to require an RTS. For packets with a
size below RTS Threshold value, an RTS is not sent and the packet is
transmitted directly to the WLAN.
Max Multicast Rate – Multicast and Broadcast transmissions are not
acknowledged, therefore the chance of error increases. By default, the unit will
always transmit broadcasts, multicasts and control frames in the minimum
possible rate, 1Mbps.
Power Save Support – If you enable Power Save Support on one of the
WLAN stations (SA-PCR only), you must also configure the AP unit. Power
Save Support is influenced by two parameters:
DTIM Period – Determines at which interval the AP will send its broadcast
traffic to all the stations in the cell, both stations that are in power save mode
and to stations that are not in power save mode (normal mode). When stations
that are in power save mode "wake up" to receive broadcast frames, they can
also poll the AP for the unicast frames if there are any stored in the AP's
buffer. Default value is 4 beacons (approximately every 1 second).
IP Stack – By default this parameter is disabled, to check connectivity. Any
changes to this parameter will be returned to the default value whenever the
unit resets.
Acknowledge Delay – Enlarges the range of system but can only be enabled
for links above 20kms. It must be enabled on both sides. The values are Long
or Regular (default) and can be configured by an Installer or Technician.

Using the Local Terminal for Unit Setup and Management
DTIM interval on the AP side – Determines at which interval the AP
will send its broadcast traffic (default 4 beacons).
Listen interval on the SA-PCR side – Determines when the station will
"wake up" to listen to unicast packets which are destined to it (default
value: 4 beacons).
