5.4.3 Set Uplink Gain
It may be necessary to adjust the Uplink gain of the mBSC-C system in order to achieve a balanced forward
and reverse link, or to adjust for other conditions (antenna placement, dynamic range requirements,
propagation characteristics at different bands, specific RF design). The MBSC0800-040-RU provides two
points of adjustment for uplink gain:
1. Software controlled attenuator for each band in the BIU
2. Software controlled attenuator in each band-specific Remote Unit
The determination of appropriate values for these parameters is outside the scope of this document.
5.4.3.1 Adjust BIU Uplink Attenuator
Adjust the BIU uplink attenuation value for each frequency band as follows:
1. Click on the BIU in the topology diagram and the component window will pops up on the right as
shown in Figure 50 - BIU Attenuator.
2. Uplink Attenuation Value (XXX MHz): Input the appropriate value for each frequency band (0dB –
25dB range)
3. Click Save
5.4.3.2 Adjust RU Uplink Attenuator
Adjust the RU uplink attenuation value for the specific RU / frequency band as follows:
1. Click on the RU in the topology diagram and the component window will pops up on the right as
shown in Figure 51 - RU Attenuator.
2. Uplink Attenuation Value: Input the appropriate values (0dB – 25dB range)
3. Click Save
