Maximum Station Data Rate – The maximum data rate at which the access
point transmits unicast packets on the wireless interface. The maximum
transmission distance is affected by the data rate. The lower the data rate,
the longer the transmission distance. (Default: 54 Mbps)
Maximum Associated Clients – Sets the maximum number of clients that can
be associated with a VAP interface at the same time. (Range: 1-64 per VAP
interface: Default: 64)
Antenna ID – Selects the antenna to be used by the access point; either the
integrated diversity antennas (the "Default Antenna") or an optional external
antenna. The optional external antennas (if any) that are certified for use
with the access point are listed in the drop-down menu. Selecting the correct
antenna ID ensures that the access point's radio transmissions are within regulatory
power limits for the country of operation. (Default: Default Antenna)
Note: The Antenna ID must be selected in conjunction with the Antenna Control Method
to configure proper use of any of the antenna options. This access point does not
support optional external antennas.
Antenna Control Method - Selects the use of both fixed antennas operating in
diversity mode or a single antenna. (Default: Diversity)
• 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.
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)
• 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 may be reduced when the 802.11g interface is supporting a
high number of clients simultaneously.
