Macro Base Station Installation Procedures (NPM-1000)
Pre-Upgrade Preparation
Before you begin upgrading the base station, ensure that the following preparations are performed.
These preparations are intended to minimize the interruption of service.
Site-Specific Documentation
Before upgrading the base station, ensure that the documentation described in Table B.1 is updated,
reviewed, and verified.
RF Planning
RF planners should develop a preliminary RF plot of the new sector configuration that accounts for
the location of existing and future users. A change in antenna sector layout may affect the RF planning
for the entire network.
After the RF plot is finalized, it should be added to the field deployment package.
Install Additional Antennas and Cabling
Install the new antennas and associated cabling. Each new sector requires two antennas (main and
diversity). See “Install the Main and Diversity Antennas” on page 94 for information.
After installing the antennas and cabling, perform a cable sweep on each and ensure results are within
specifications.
HVAC Requirements
Ensure that the heating, ventilation, and air-conditioning (HVAC) system for the site has the capacity
to handle the additional heat produced by the additional sectors. See “Heat Output” on page 22 for
information.
Main and Backup Power Supplies
Ensure that the power supplies for the site have the capacity to handle the additional sectors. See
“Electrical Requirements” on page 23 for information. Additional rectifier modules must be installed
and tested prior to upgrading.
Backhaul Capacity
Verify that the backhaul connecting the base station to the network core has the capacity to handle the
additional traffic.
Document Description
Field engineering package Provides site-specific configuration about the base station, such as antenna
orientation, cabling requirements, and inventory
Method of Procedure (MOP) for
adding sectors
Describes the sequence and timing of procedures required for the upgrade
Site-specific fall-back plan Describes any events or triggers that require that the technicians return the
base station to its original configuration.
