WAP43DC FAT Web Manual Chapter 4 Advance Configuration
Radio Select Radio 1or Radio 2 to specify which radio to configure. The rest of
the settings on this tab apply to the radio you select in this field. Be sure
to configure settings for both radios.
Status
(On/Off) Specify whether you want the radio on or off by clicking On or Off.
If you turn off a radio, the AP sends disassociation frames to all the
wireless clients it is currently supporting so that the radio can be
gracefully shutdown and the clients can start the association process
with other available APs.
Mode The Mode defines the Physical Layer (PHY) standard the radio uses
Note: The modes available depend on the country code setting.
Select one of the following modes for each radio interface:
IEEE 802.11a-Only 802.11a clients can connect to the AP.
IEEE 802.11b/g-802.11b and 802.11g clients can connect to the AP.
IEEE 802.11a/n-802.11a clients and 802.11n clients operating in the 5-
GHz frequency can connect to the AP.
IEEE 802.11b/g/n (default)-802.11b, 802.11g, and 802.11n clients
operating in the 2.4-GHz frequency can connect to the AP.
5 GHz IEEE 802.11n-Only 802.11n clients operating in the 5-GHz
frequency can connect to the AP.
2.4 GHz IEEE 802.11n-Only 802.11n clients operating in the 2.4-GHz
frequency can connect to the AP.
Channel Select the Channel.
The range of available channels is determined by the mode of the radio
interface and the country code setting. If you select Auto for the channel
setting, the AP scans available channels and selects a channel where
no traffic is detected.
The channel defines the portion of the radio spectrum the radio uses for
transmitting and receiving. Each mode offers a number of channels,
depending on how the spectrum is licensed by national and
transnational authorities such as the Federal Communications
Commission (FCC) or the International Telecommunication Union (ITU-
R).
Note: When automatic channel assignment is enabled on the Channel
Management page for Clustering, the channel policy for the radio is
automatically set to static mode, and the Auto option is not available for
the Channel field. This allows the automatic channel feature to set the
channels for the radios in the cluster.
Channel
Bandwidth
(802.11n
modes only) The 802.11n specification allows a 40-MHz-wide channel in addition to
the legacy 20-MHz channel available with other modes. The 40-MHz
channel enables higher data rates but leaves fewer channels available
for use by other 2.4 GHz and 5 GHz devices.
Set the field to 20-MHz to restrict the use of the channel bandwidth to a
20-MHz channel.
Primary
Channel
(802.11n
modes only) This setting can be changed only when the channel bandwidth is set to
40 MHz. A 40-MHz channel can be considered to consist of two 20-MHz
channels that are contiguous in the frequency domain. These two 20-
MHz channels are often referred to as the Primary and Secondary
channels. The Primary Channel is used for 802.11n clients that support
only a 20-MHz channel bandwidth and for legacy clients.
Select one of the following options:
Upper-Set the Primary Channel as the upper 20-MHz channel in the 40-
MHz band.
Lower-Set the Primary Channel as the lower 20-MHz channel in the 40-
MHz band.
