Configuration MP.11-R Installation and Management
Interface Parameters
88
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.
• Lower Frequency Edge Filter(in MHz): This parameter is used to configure Low Frequency Edge Filter in MHz. By
default, the Low Frequency Edge Filter value is 0.This parameter is applicable in 11a mode only.
• Upper Frequency Edge Filter(in MHz): This parameter is used to configure High Frequency Edge Filter in MHz. By
default, the High Frequency Edge Filter value is 10,000.This parameter is applicable in 11a mode only.
NOTES:
• If you enter an invalid value for Edge Frequency, the device takes its default value. Lower Frequency Edge
value should always be less than the Upper Frequency Edge value.
• Use the above Lower and Upper Frequency Edge Filters to restrict the available frequency band. For e.g.: If
you configure the Lower and Upper Edge Frequency Filter as 5700MHz and 5800MHz, then the list of
frequency channels is restricted to 142 (5710), 146(5730), 150(5750), 154(5770), 158(5790).
• 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.
For countries/bands in which DFS is required, Frequency Channel is not configurable. Instead the channel is auto-
selected by the DFS process.
On 5054-R/-LR World units, 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.
• DFS Backup Channel Status: This field appears only if a US-DFS Country is selected from the Configure >System
page. The device operates in channel 149 when all channels are blacklisted.
• 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 when roaming enabled.
• Multicast Rate: The rate at which data is to be transferred. This drop down box is unavailable when DDRS is
enabled.
The default multicast rate for the unit 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.
