7.2.3 HRU Commissioning
HRU composite downlink output level can be determined using simulation tools like iBwave. User should
simulate this output level in order to ensure that all service areas have sufficient coverage.
x The simulated composite DL output power value should not exceed the maximum output level of the HRU,
which is 43dBm.
x The simulated composite DL output power value would be used as HRU DL commissioning output level. DL
attenuation value will be adjusted automatically based on this simulated value HRU commissioning level.
For HRU commissioning, user should enter information on DL output commissioning level. Refer to section
7.2.2.1 to calculate DL output commissioning level.
x Go to Install page of Remote Module on the webGUI
Figure 7-8 Remote Module Install Window
x Enter HRU downlink output commissioning level
- Output range: 5~+43dBm, 0.5dB step
x Press the “Apply” button
x The attenuation level for each DL/UL path will be set automatically based on DL Output Commissioning Level
that is entered
x Checks to see if DL output is low.
- During the commissioning routine, if DL output level is 10dB less than commissioning level, a
popup message will appear stating that DL output is low. If this is the case, then there is a chance
that the “back-off” value needs to decrease breathing room.
x Checks to see if ALC is is active.
- During the commissioning routine, if ALC is activated, a popup message will appear stating that
ALC is running. If this is the case, then there is a chance that the “back-off” value needs to be
increase to allow more breathing room.
x Checks to see if the Sub-RU has any alarms.
- If a soft fail is present, the system will prompt the user whether or not they would like to
continue.
- If hard fail is present, the commissioning process will stop immediately.
x Commissioning is successfully completed.
