ProSafe Premium 3 x 3 Dual-Band Wireless-N Access Point WNDAP620
Beacon Interval (100–1000) Enter the interval between 100 ms and 1000 ms for each beacon
transmission, which allows the wireless access point to synchronize
the wireless network. The default setting is 100.
Aggregation Length (1024–65535)
Note: This setting does not apply
to the 80
2.11a mode.
Enter the maximum length of aggreg
ated MAC protocol data unit
(A-MPDU) packets. Larger aggregation lengths could lead to better
network performance. Aggregation is a mechanism used to achieve
higher throughput. The default setting is 65535.
AMPDU
Note: This setting does not apply
to the 80
2.11b/bg modes and the
802.11a mode.
Select the Enable rad
io button to allow the aggregation of several MAC
frames into a single large frame to achieve higher throughput. Enabling
the aggregated MAC protocol data unit (A-MPDU) could lead to better
network performance. By default, the Enable radio button is selected.
RIFS Transmission
Note: This setting does not apply
to the 80
2.11b/bg modes and the
802.11a mode.
Select the En
able radio button to allow transmission of successive
frames at different transmit powers. Enabling reduced interframe space
(RIFS) could lead to better network performance. By default, the
Disable radio button is selected.
DTIM Interval (1–255) Enter the delivery traffic indication message (DTIM) interval, also
referred
to as the data beacon rate, which indicates the beacon
delivery traffic indication message period in multiples of beacon
intervals. This value needs to be between 1 and 255. The default
setting is 3.
Preamble Type
Note: This setting does not apply
to the 80
2.11a/na modes.
Select one of the following radio buttons to specify the preamble type:
• Long. A long transmit preamble might provide a more reliable
connection or a slightly longer range. A short transmit preamble
gives better performance.
• Auto. Th
e Auto setting enables the wireless access point to handle
both long and short preambles. The default setting is Auto.
Antenna
Note: This setting does not apply
to the 80
2.11a/na modes.
Select one of the following radio buttons to
specify the antenna:
• In
ternal. Enables the internal antenna. This is the default setting.
• External.
Enables an optional external antenna or antennas.
802.11d
Note: This setting does not apply
to the 802.11a/na modes.
Select this check box to enable support for additional regulatory
domains that are not in the current standard; support includes the
addition of a country information element to beacons, probe requests,
and probe responses. This check box is selected by default.
Client Isolation From the drop-down list, select
one of the following options:
• Enable. Co
mmunication between wireless clients that are
associated to different virtual access points (VAPs) is blocked.
• Disab
le. Communication between wireless clients that are
associated to different VAPs is allowed. This is the default setting.
Max. Wireless Clients Enter the maximum number of wireless clients that can simultaneously
conn
ect to the wireless access point at one time. The default setting is
128 clients.
