LABEL DESCRIPTION
Hide / Show Click this to hide or show the Advanced Settings in this window.
Advanced Settings
Create New Object Select an item from this menu to create a new object of that type. Any objects created
in this way are automatically linked to this radio profile.
General Settings
Activate Select this option to make this profile active.
Profile Name Enter up to 31 alphanumeric characters to be used as this profile's name. Spaces and
underscores are allowed.
802.11 Band Select the wireless band which this radio profile should use.
2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients.
Mode If you set 802.11 Band to 2.4G, you can select from the following:
•
•
Channel Select the wireless channel which this radio profile should use.
It is recommended that you choose the channel least in use by other APs in the region
where this profile will be implemented. This will reduce the amount of interference
between wireless clients and the AP to which this profile is assigned.
Advanced Settings
Channel Width Select the channel bandwidth you want to use for your wireless network.
Select Auto to allow the NWA to adjust the channel bandwidth depending on network
conditions.
Select 20 MHz if you want to lessen radio interference with other wireless devices in
your neighborhood.
Guard Interval Set the guard interval for this radio profile to either short or long.
The guard interval is the gap introduced between data transmission from users in order
to reduce interference. Reducing the interval increases data transfer rates but also
increases interference. Increasing the interval reduces data transfer rates but also
reduces interference.
Enable A-MPDU Select this to enable A-MPDU aggregation.
Aggregation
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with
their 802.11n headers and wraps them in a 802.11n MAC header. This method is useful
for increasing bandwidth throughput in environments that are prone to high error
rates.
Enable A-MSDU Select this to enable A-MSDU aggregation.
Aggregation
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of
their 802.11n headers and wraps the header-less payload in a single 802.11n MAC
header. This method is useful for increasing bandwidth throughput. It is also more
efficient than A-MPDU except in environments that are prone to high error rates.
Chapter 9 AP Profile
b/g: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the NWA. The NWA adjusts the transmission rate automatically
according to the wireless standard supported by the wireless devices.
b/g/n: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the NWA. The transmission rate of your NWA might be
reduced.
