3 COMMISSIONING
This section is NOT a guide for the full commissioning procedure! System commissioning can be performed
by the user in many different manners. It is up to the technician who has all the project details to decide in
which order and what steps to commission the BDA system per the project requirements. The following
sections provide an overview of the steps Comba recommends taking when commissioning the system. Some
steps may be skipped or omitted if they do not apply to your application.
It is also important that the technician commissioning the system is an authorized operator. Please refer to
Section 0.12 for more details on who is authorized to operate the equipment.
Signal Boosters/Zone Enhancers (Also referred to BDAs or Fiber Fed BDAs) are not consumer devices. They
are industrial devices which may only be operated and maintained by authorized individuals and qualified
installers.
1. Operators of the equipment MUST have taken and passed Comba Telecom’s certification
training for RF101 and the V3 BDA/DAS/BBU product line.
2. Operators of the equipment MUST have a valid FCC General Radio Operator License (GROL) if
operating the device in the USA.
3. Operators of the equipment MUST have NICET Level 3 Certification IB-PSC; or they MUST have
NICET Level 2 Certification IB-PSC and be supervised by someone who has NICET Level 3 IB-
PSC if operating the device in the USA.
4. Installers of the equipment MUST have NICET Level 2 Certification IB-PSC or higher; or they
MUST have NICET Level 1 Certification IB-PSC and be supervised by someone with NICET Level
2 Certification IB-PSC or higher while operating the device in the USA.
5. Non-Licensee Operators MUST receive express written consent to operate the Signal
Booster/Zone Enhancer from the FCC/ISED License Holder BEFORE installing and operating
the device.
3.1 PRE-COMMISSIONING TASKS
After equipment installation, perform the following steps before equipment power up and commissioning:
• Verify that the expected voltage, current and power levels do not violate any ratings.
• Visually inspect all power and communications wiring connections within the equipment. Ensure that all
cables are correctly and securely connected including the AC and DC power wires, grounding wire, RF
cables and other cables.
• Check the grounding connection and verify that the ground resistance is less than 5Ω.
• Evaluate the antenna system and ensure that the system return loss within working frequency is less than
-14dB (VSWR<1.5).
• Ensure all RF connections are completed or terminated with loads. See Section 2.23 for more details.
• Gather the required RF inputs for system commissioning. See Section 3.2
