NOTE
•This document aims to provide simple and distinctive guidelines for hardware installation.
•This document does not describe operations for the pre-delivery installation. Instead, this document
describers only the operations for on-site installation.
•This document describes how to connect the ATOM GPS to the GPS Satellite Antenna System. The ATOM
GPS consists of the indoor NE08E and AE 905S. This example uses the NE08E-S6.
•For requirements on the GPS installation, see GPS Satellite Antenna System Quick Installation Guide.
•For requirements on the GPS antenna position, see Appendixes 2.

•EHS requirements: The installation personnel should wear safety belts, helmets, shoes, and gloves for
climb operations.
•Exercise caution when touching the device with the high temperature identification to avoid scalding.
•When installing or maintaining fibers, do not look into the optical port without eye protection. The infrared
laser emitted by the optical interfaces can cause permanent eye damage.

NOTE
Use cables delivered with Huawei devices or cables complying with Huawei standards.

If you need to install two AE 905Ss on a device, separately

installing them on the optical interfaces of two boards is
recommended. If you need to install two AE 905Ss on the
same board, inserting the modules at an interval of at least
four optical interfaces is recommended.

2 Requirements for GPS Antenna Installation Positions

NOTE
This describes the requirements for the installation positions of the GPS antennas under different
installation environments.
General Requirements

1.The GPS antenna should be installed in an open space and is far

from high buildings. The GPS antenna has a vertical visual angle no ≥ 90°
less than 90°, as shown in Figure 1.

2.The GPS antenna should be installed in the protection range of the
lightning rod (within the tilt angle of 45° under the lightning rod). The
horizontal distance between the antenna and the lightning rod should
be longer than 2 m, as shown in Figure 2.

3.If multiple GPS antennas are installed, ensure that the horizontal Figure 1
distance between antennas is greater than 0.5 m.

4.The GPS antenna should be far from: 45°

•High-voltage power cables >2m
•Strong radiation area of the TV transmission station
•Radiation area of the main lobe of the RF antenna

near the tower.
2.The GPS antenna should not be installed in the following areas:
•Any area on the tower body
•Cabling rack between the tower and the equipment room

Requirements for Installation on the Pole

2.When the GPS antenna and the main equipment are installed on the same pole, the vertical distance
between them should be less than 2 m.
