Chapter 5 Commissioning
Preparations
The minimum of preparations necessary are to have the system documentation which should include the following
items at least:
 The system layout and block schematic
 A connection diagram for the head-end Master Unit
 The type of connectors and tappers used to interface to the base station ports
 The number of carriers for each of the BIU that the base stations connects via
 Maximum output power for each service from the base stations
 Fiber losses should be documented beforehand so that you can compare what the system actually
measures
 Sectorization information, which sectors should go to which remotes
 DAS calculator sheets showing the expected settings for each of the RF chains in uplink and downlink.
 Information about Ethernet connection if the system should be monitored by remote. How to connect it to
the Internet for remote viewing unless you are using a modem.
Necessary tools
The tools necessary to commission the system includes:
 One laptop for changing the system settings, checking any alarms and status. Only software needed is a
web browser. Operating system can be Windows, Linux or Mac as you prefer.
 Spectrum analyzer to measure the uplink. The system relies on test tone measurements in the uplink and
therefore it is important to have equipment to measure them.
 SMA tool to be able to connect or disconnect BTS cables from the BIU.
 QMA adapter so you can measure signals directly on the head-end units such as the FOI, BIU, ICU and so
on.
Software
No particular software is necessary except a modern graphical based web browser.
