• Enable Turbo Mode (Non-DFS US Only): Check this box to enable Turbo Mode. Turbo Mode is supported only in
the United States. Enabling turbo mode, in its current implementation, allows the unit to use two adjacent frequency
channels to transmit and receive a signal. By enabling turbo mode, the receive sensitivity improves by 4 dB for the 36
Mbps data rate and by 2 dB for the 24 Mbps data rate.
NOTE: The additional sensitivity is provided with the impact of using twice as much spectrum and thus increasing the
opportunity of interference and decreased ability for system collocation. Generally, Turbo mode is not
recommended except when the extra sensitivity is absolutely required.
• Frequency Channel: The frequency channel indicates the band center frequency the unit uses for communicating
with peers. This frequency channel can be set in several ranges, depending upon the regulatory domain. Refer to
Country Codes and Channels for channelization information. For countries in which DFS is not required, the
Frequency Channel list displays only the channels and frequencies allowed for the selected country/band.
For countries in which DFS is required, Frequency Channel is not configurable. Instead the channel is auto-selected
by the DFS process.
If All Channels 5 GHz is selected in the Country drop-down menu on the Configure > System page, any channel in
the 5 GHz range is manually selectable.
• Scanning Across Bandwidth: Enable this field if you want the SU to scan across the whole range of channel
bandwidths (5, 10, or 20 MHz, as available) with or without roaming enabled. Disable this field if you wish the SU to
scan only across its configured channel bandwidth.
• Multicast Rate: The rate at which data is to be transferred. All RF traffic between 5012/5054-SUI units is multicast.
This drop down box is unavailable when DDRS is enabled.
The default data rate for the 5012/5054-SUI is 36 Mbps. The SU must never be set to a lower data rate than the BSU,
because timeouts will occur at the BSU and communication will fail.
Selections for multicast rate are shown in the following table:
• Channel Bandwidth: This field is used to change the bandwidth. Values are 5 MHz, 10 MHz, or 20 MHz, as well as
40 MHz when Turbo mode is enabled.
NOTE: The 5 MHz channel bandwidth is not available when the selected country is UNITED STATES DFS.
• Satellite Density: The Satellite Density setting is a valuable feature for achieving maximum bandwidth in a wireless
network. It influences the receive sensitivity of the radio interface and improves operation in environments with a high
noise level. Reducing the sensitivity of the unit enables unwanted “noise” to be filtered out (it disappears under the
threshold).
You can configure the Satellite Density to be Large, Medium, Small, Mini, or Micro. The default value for this
setting is Large. The smaller settings are appropriate for high noise environments; a setting of Large would be for a
low noise environment.
A long distance link may have difficulty maintaining a connection with a small density setting because the wanted
signal can disappear under the threshold. Consider both noise level and distance between the peers in a link when
configuring this setting. The threshold should be chosen higher than the noise level, but sufficiently below the signal
level. A safe value is 10 dB below the present signal strength.
