RF Switch: Set the RF switch status of Remote Unit. Target DL Output Power: Expected DL output power setting. Note: Rated output power of ComFlex system is 30dBm, when Target DL Output Power is set less than 30dBm, software will auto adjust RU gain to make the RU output power reach the expected Power. Step 8: Click to enter to [Finish] page after finishing RU setup. Click to calibrate other bands. Click if all bands clibration is done. Figure 75: Commissioning Procedure Finish Note:
As the system calibration process is calibrated for single channel, so if there is more than one same band input, because of the power superposition, the band total output power will higer than target DL output power after the calibration is complete. The calibration work is mainly to set device to reach its theoretical gain, so when there are two or more same bands access into and they have the same input power level, each channel will reach its rated ENU STATUS : 1-0-0 Copyright - refer to title page Page 56 USER MANUAL FOR COMFLEX 6100 1W power, so the total output power will be (input A+gain) + (inputB+gain)++(inputN+gain). For example, if there are two 1900MHz bands acess to MU, each has 10dBm input power, the total output power of RU 1900MHz will be 30dBm+30dBm=33dBm. For Multi-channel same band access, 800+850 (which share the same PA) access and 700 Uper C +
LowerABC (also shared PA), they all will have power superposition. In this situation, users need to adjust system gain manually; otherwise, the output power will be higher than 32dBm which will trigger alarms
(See Chapter 6 for details). Refer to the method below for the gain adjustment:
Suppose a band with N independent inputs, each input signal power are all X dBm. Apparently, there exists the following relationship between input and output after finished auto communication on WEB GUI:
X dBm + Gain = 30dBm, then the total output power for N channels access is X dBm + Gain + 10*Log(N)
= 30 + 10*Log(N), so Users need to set 10*Log(N) RFU ATT on WEB GUI for each channel.
