Field Name
Description
mended to use only non-overlapping channels, e.g., 1 , 5 and 7 . The default is
Auto .
Auto Channel Timer
Enter the frequency (in minutes) at which the gateway scans channels for inter-
(min)
ference. If a threshold of inference is detected, a new channel will be selected
automatically. Options are 0 - 65535 minutes. The default is 15 minutes.
MIMO-OFDM
Select whether MIMO-OFDM (multiple-input multiple-output with orthogonal fre-
quency-division multiplexing) is enabled.
For the 5GHz band, this option is set to Auto and cannot be changed.
For the 2.4 GHz band, options are Auto and Disabled. The default is Auto.
Bandwidth
Select the operating bandwidth. Options are:
( Applies only to 40 MHz operation ) The control sideband is the 20 MHz channel on
Control Sideband
which the network is advertised, where client devices will find beacons. This field
is set to Lower and cannot be changed. The additional 20 MHz of bandwidth for
data will be positioned above the control channel.
MIMO Data Rate
Select the desired physical transmission rate.
For the 5 GHz band, this option is set to Auto (the Auto-Fallback feature is
enabled) and cannot be changed. This allows the gateway to automatically use
the fastest possible data rate. Auto-Fallback will negotiate the best possible con-
nection speed between the gateway and a wireless client.
For the 2.4 GHz band, the options are Auto and 0 - 15. The default is Auto.
RTS/CTS Protection
Select whether to enable 802.11n and legacy clients to both work effectively on
the network. Options are:
Support MIMO Clients
Select whether to restrict non-MIMO clients from accessing the gateway. Options
are On and Off . The default is Off .
Only
RIFS Advertisement
Reduced Inter-Frame Space (RIFS). Improves performance by reducing dead time
required between OFDM transmissions. Options are Auto and Off . The default is
Auto .
Recommended primarily for "greenfield" deployments that include only 802.11n
clients, and no legacy clients.

20MHz: Only one 20MHz band is utilized.
l
40MHz: Better throughput is provided by using two adjacent 20MHz bands.
l
80MHZ: (Available for 5 GHz band only) Best throughput.
l
Auto: Provides maximum security but produces a noticeable impact on
l
throughput. With this option, RTS/CTS behavior permits legacy clients to
become aware of 802.11n transmit times, but decreases overall through-
put. This is the default.
Off: Provides better throughput.
