5. Define the Downlink Channels:
•
Set the
Start
and
Stop
DL Frequency (MHz). (The Uplink Start and Stop
frequencies will be automatically allocated.)

Set
Max Gain: c
hange the default value (maximum) according to the
measured/calculated input power and isolation measurements.
More information on DL sub-band parameters:
•
DL Set Ch. Max. Gain - Sets the power for the antennas. Recommended
Maximum Gain setting is approximately 16 dB less than the isolation between
the service and donor antennas.
•
DL Measured RSSI - measured DL signal.
•
DL Measured Ch. Gain - measured DL Gain (dB) for the selected sub-band.
•
DL Measured Ch. Power - measured Power (dBm) for the selected sub-band.
6. Set the Uplink parameters:
NOTE: The uplink channels are automatically allocated according to the downlink channel
definitions.
If the site NOISE LEVEL causes interference, adjust the noise level as follows:
•
Adjust the Gain Delta parameter – this sets the delta between the uplink and
downlink gain (so the uplink gain is relatively lower than the downlink gain.
•

.
•
Repeat the procedure until the desired coverage is achieved.
More information on DL sub-band parameters:
•
UL Gain ∆ - used for noise control. Sets the difference between UL and DL gain.
•
UL Measured Ch. Gain - measured UL Gain (dB) for the selected sub-band.
