5. Define the Downlink Channels:
• Set the Start and Stop DL Frequency (MHz). (The Uplink Start and Stop
frequencies will be automatically allocated.)
• Sub-band resolutions ranging between 200KHz and 1MHz can be allocated to a
narrowband or wideband filter. In this case, you will be prompted to select the
filter type
o Select the filter type and click Select and Return.
o Click Send at the top of the screen.
• Set M
ax Gain: change 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.
• Click Send.
• 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.
7. Click Send (top window area option).
