Precautions
•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.

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

Introduction to the ATOM GPS
Before inserting an AE 905S to an optical interface, lock the
ejector lever. Before removing an AE 905S from an optical
interface, loosen the ejector lever.
Although the AE 905S can be inserted into an optical
interface, it cannot be installed on an NED1EG2 board.
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.
Loosen the ejector lever.

Insert the AE 905S into an optical interface of
the NE08E device, with the wrench on the AE
905S being locked.
Connect the other end of the coaxial cable to
the AE 905S.
The coaxial cable must be routed without affecting the
cabling of neighboring boards.
Do not connect the coaxial cable to any AE 905S
inserted into an optical interface adjacent to another

Assembling OT Terminals
Material: OT terminals (ring terminals) , heat-shrinkable tube and cable.
Strip a part of the jacket off the cable to expose the
conductorwith a length of L1.
L1 = 23 mm to 25 mm
L1
Conductor
When stripping the jacket off the cable, do not
damage the metal conductor of the cable.
Press the end of the contact terminal on the
conductor by using the crimping tool.
Heat the heat-shrinkabletube by using a heat gun.
Lead the cable through the heat-shrinkable tube,
and then place the contact terminal on the
exposed conductor.
A: heat-shrinkable
B: OT terminals
•Close contact between the contact terminal and the end of
the jacket of the cable is required.
•When placing the contact terminal on the conductor
closely to the end of the jacket, ensure that the L2 part of
the conductor which sticks out of the contact terminal
cannot exceed 2 mm.
C: power cable

Figure 2
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
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.

Requirements for Installation near the Tower
1.The GPS antenna should be installed on the top of the equipment room or of the outdoor macro-BTS
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
