Fusion Wideband Installation Procedures

CONFIDENTIAL D-620616-0-20 Rev F
• Select the Center Frequency and Bandwidth using the arrows next to the fields.
The center frequency is the frequency of WiMAX radios being used for Band 1
and Band 2.
NOTE: In MIMO mode, the frequencies are the same. The system can be
configured to support 2-SISO radios, one per band, across any 30 MHz
within the WiMAX band.
• Use the pull-down to select the Switching Mode. This indicates whether or not
the downlink-to-uplink frame duration is known. The two options are as fol-
lows:
– Static-Selected: This mode specifies the number of symbols. Use the
pull-down to select the symbol in the downlink and uplink portions of the
frame. (The default is “29,18”.) In this mode, the system always switches
from the downlink to the uplink path after the downlink portion of the frame
has elapsed.
– Static-Auto: This mode causes the system to attempt to determine the cor-
rect switching time, then enforce it. (The default is “Static-Auto”)
• Select the Band Synchronization Mode with the pull-down. This parameter can
be configured to operate as one of the following:
– Synchronized: This mode is for cases like MIMO, where the timing for
both bands is the same. In this mode, the system always switches between
uplink and downlink simultaneously for both bands.
– Unsynchronized: In this mode, the two WiMAX bands switch indepen-
dently from each other. (The default is “Unsynchronized”)
• Reference: Select which WiMAX radio band will be used for frame reference.
• When any band is not configured, use the Shutdown check box. The system
ignores any alarms generated from the shutdown bands.
• Use the pull-down to specify the Uplink and Downlink gain for each band. You
can set system gain within the specified range in 1 dB increments.
• Use the pull-down to set the Uplink Automatic Level Control to either “Single”
or “Multiple” for each band in the system. (The default is “Multiple.”)
