5.5 Configure the Band
According to the different base station operating frequency bands for each operator, the
following must be set:
● The active RF modules for the C-hub and the active RF modules for the RUs with the
corresponding frequency band
● The frequency band of carrier bundles
The limits of the uplink and downlink operating frequency bands correspond to the effective
RF range of the selected RF modules; see Fig. 11.
1. Open the master C-hubs web GUI as described under 4.3, p. 15/4.4, p. 23.
2. Go to Settings ▶ Band Configuration.
3.
Tip
Make sure that the maximum bandwidth per carrier bundle is less than
40 MHz and the maximum bandwidth for all operators is less than 280 MHz.
For the channels 1 to 4, set the uplink and downlink centre frequencies and the
bandwidth for the carrier bundles (② in Fig. 11).
4. Press Set ③ to conrm the changes.
5. Ensure the value of CH1~4 info is valid.
6. Set AU CH Info Update to Update ④.
