Wireless Interface Configuration
Configuring the Radio
Configuring the Radio Channel and Other Basic Settings
The access point uses the configured radio channel to communicate with
wireless stations. As indicated in the
“Radio Configuration Summary Table” on page 6-6
,
the access point’s channel settings and radio mode have a configuration
relationship to enhance the performance of the access point.
The channel spectrum depends on the country of operation, the MHz or GHz
bands desired, and specific country regulations. The country of operation
might also enable specific features; for example, a European community or
EFTA requires a radar detection feature for use in a 5 GHz band. Once the
country is configured, this feature is automatically enabled on the access
point.
N o t e
If you are using the worldwide product (J8987A), you must set the country
code, using the CLI, before you can configure the radio settings. See
“Setting
the Country Code” on page 6-4
. Use the write mem command to save the setting.
Web: Configuring Basic Radio Settings
The Network Setup – Radio screen, shown in Figure 6-2, configures basic
settings for the access point’s radio operation. For the Advanced Settings, see
“Web: Configuring Advanced Radio Settings” on page 6-14
.
The Web interface enables you to modify these parameters:
■ Max Tx Power: The maximum power in dBm that the current radio mode
supports. (The default is
0
.)
■ Tx Power Reduction:
Adjusts the power of the radio signals transmitted
from the access point (radio attenuation). This control should be used to
reduce the AP radio cell size, or compensate for higher gain external
antennas. If set to 0 dBm, the radio is operating at maximum power.
(Default is
0
). For the configuration of Transmit Power, see
“Web: Setting the
Tx Power Reduction” on page 6-23
.
■ Channel: The radio channel that the access point uses to communicate
with wireless stations. The range of channels and the default channel are
determined by the radio mode and country of operation. Linked to auto
channel select (ACS). When ACS is enabled, it displays channel settings.
When ACS is disabled, the channel options are dimmed and the radio
channel is set automatically. (The default is variable, depending on the
radio mode and access point model)
