correct antenna ID ensures that the access point's radio transmissions
are within regulatory power limits for the country of operation. (Default:
Default Antenna)
Antenna Control Method—Selects the use of both fixed antennas operating
in diversity mode or a single antenna. (Default: Diversity)
•
•
•
Antenna Location—Selects the mounting location of the antenna in use;
either Indoor or Outdoor. Selecting the correct location ensures that the
access point only uses radio channels that are permitted in the country of
operation. (Default: Indoor)
MIC Mode—The Michael Integrity Check (MIC) is part of the Temporal Key
Integrity Protocol (TKIP) encryption used in Wi-Fi Protected Access (WPA)
security. The MIC calculation is performed in the access point for each
transmitted packet and this can impact throughput and performance. The
access point supports a choice of software or hardware MIC calculation.
The performance of the access point can be improved by selecting the best
method for the specific deployment. (Default: Software)
•
•
Super A—The Atheros proprietary Super A performance enhancements are
supported by the access point. These enhancements include bursting,
compression, and fast frames. Maximum throughput ranges between 40 to
60 Mb/s for connections to Atheros-compatible clients. (Default: Disabled)

Note: The Antenna ID must be selected in conjunction with the Antenna
Control Method to configure proper use of any of the antenna options.
Diversity: The radio uses both antennas in a diversity system. Select
this method when the Antenna ID is set to Default Antenna to use the
access point's integrated antennas.
Right: The radio only uses the antenna on the right side (the side closest
to the access point LEDs). Select this method when using an optional
external antenna that is connected to the right antenna connector.
Left: The radio only uses the antenna on the left side (the side farthest
from the access point LEDs). Select this method when using an optional
external antenna that is connected to the left antenna connector.
Hardware: Provides best performance when the number of supported
clients is less than 27.
Software: Provides the best performance for a large number of clients
on one radio interface. Throughput can be reduced when both 802.11a
and 802.11b/g interfaces are supporting a high number of clients
simultaneously.
