7 Installing the Cabinet Internal Cables
Summary
This part describes:
●
Configuration types of BTS and precautions of the
installation of the front panel RF cables;
●
Cable installation in BTS single-carrier and two-carrier
configurations;
●
Cable installation in BTS three-carrier above
configurations.
7.1 Overview of the Internal Cable Installation
7.1.1 Configuration Types of BTS
A macro BTS can be configured in various ways, e.g., single-carrier three-sector,
two-carrier three-sector and four-carrier three-sector as required by the installation
environment and traffic conditions.
The RFE model varies with the BTS configuration and the number/length of
connection lines configured for the front panel of the rack. The following sections
describe the typical configurations: Single-carrier single-sector, single-carrier
two-sector, single-carrier three-sector, and two-carrier three-sector.
7.1.2 Precautions for Installing the RF Cables on the Front Panel
The front panel of the BTS rack uses RF cables to transmit the uplink and downlink RF
signals between RFE, HPA and TRX. N-type interfaces and SMA interfaces are use.
During the cable installation, make sure to align the cables to the interfaces and screw
them tight.
Generally, the RF cables have been deployed for a new base station and what needs to
do is only take the feeder connectors out of the cabling trough on the front panel and
