Mode
The Mode defines the Physical Layer (
PHY ) standard being used by
the radio.
Note
With a two-radio access point, different modes may be available
depending on whether radio one or radio two is selected in the
Radio field above.
Atheros Turbo 5 GHz is IEEE 802.11a Turbo mode.
Atheros Turbo 2.4 GHz is IEEE 802.11g Turbo mode.
Super AG
Enabling Super AG provides better performance by increasing radio
throughput for a radio mode (IEEE 802.11b, g, a, and so on). Keep in
mind that, with Super AG enabled, the access point transmissions will
consume more bandwidth. To enable Super AG click
Enabled . To
disable Super AG click Disabled .
Channel
The channel defines the portion of the radio spectrum that the radio
uses for transmitting and receiving. The range of channels and the
default channel are determined by the Mode of the radio interface.
For most Modes, the default is Auto. Auto is the recommended mode
because it automatically detects the best channel choices based on
signal strength, traffic loads, and so on.
Channels operate in a specific frequency range. The available
frequencies depend upon the country, as shown in Table 5
.
