Overview
1.1
Objective of Survey
Internal Use Only▲
Project survey is an important step before project implementation. Its primary purposes
are to obtain reliable data through project survey, and lay a foundation for engineering
design, network planning and future project implementation. Through project survey by
relevant professionals, it can be decided that whether the site is appropriate for building
a site, and how to build the site if appropriate. All such work needs to be performed on
site. The solutions prepared by the on-site engineers are subject to approval of all parties
involved, such as whether the construction cost is reasonable, whether the future
coverage effect is consistent with the predetermined construction solution.
In a word, without project survey, most of our construction mindsets are groundless and
impracticable. Before survey, we need to lay down a survey plan, clarify the survey
objectives, and obtain all data that we need.
1.2
Function of Survey
The main functions of project survey are to determine the construction solutions, and
obtain reliable data through project survey. The details are as follows:
1.3
1.
It guarantees accurate production arrangement plan and timely delivery according
to the contract.
2.
It is the original reference for data configuration and commissioning of the
production line.
3.
It is the original materials of the project handover report.
4.
It is one part of project standardization management.
Principles of Survey
Survey should be performed in accordance with the specifications. The survey results
should be clear, and no ambiguous conclusion is allowed.
The survey should stick to facts. No false or fabricated data is allowed.

Environment Survey
3.1
Overview
During project design, select proper position for building equipment room that meets the
requirements of communications equipment project design, in accordance with the
communications network planning and technical specifications, and taking into
consideration other factors such as hydrology, geology, and transportation. It is
necessary to consider the permanence of the equipment room, which should not be
relocated unless absolutely necessary once it is set up, since smooth mobile
communication network is vital to the society. Therefore, durability should be considered
when designing the equipment to avoid frequent renovation. Additionally, equipment
room should comply with fire prevention and anti-quake requirements.
The design of items such as building, structure, ventilation, power supply, illumination,
temperature control, and fire fighting should be carried out by professionals in strict
ZTE Confidential Proprietary

9
ZXG10 iBSC (V8.00.00) Project Survey Guide
Internal Use Only▲
accordance with related technical specifications of post and telecommunications. The
design of the equipment room shall satisfy the related regulations on industrial planning,
environmental protection, fire fighting and civil air defense. It shall also comply with
current national standards and specifications, as well as regulations and requirements
related to house and building design in special technologies design.
The equipment room should have a layout that facilitates the signal/power cable laying
and routine maintenance. Avoid roundabout wiring to save investment on cables and
facilitate maintenance while reducing communication failures and improving efficiency.
Environment inspection is divided into two stages: Preliminary inspection and
pre-installation inspection. The preliminary inspection is performed by the survey
engineer of ZTE in project survey. The inspection result should be reflected in the
environment checklist authentically. For the part incompliant with the standards, notify
the operator in writing to make correction, and keep track of the progress of correction.
Pre-installation inspection is performed by the project supervisor of ZTE before
installation. The inspection items are to confirm the results of the previous inspection and
the corrective measures taken, in order to ensure that the installation environment meets
the construction conditions and the installation can go on smoothly. Since pre-installation
inspection is included in the work of installation, it is not reiterated here any further. The
installation environment inspection herein refers to preliminary inspection.
3.2
Reference Requirements & Fill-in Precautions
for Environment Survey
3.2.1
Inspection on the Environment in Equipment Room
Check the following items before installation in the equipment room to be installed with
iBSC equipment:
3.2.1.1
Buildings & Bearing
1.
Location of the equipment room: road name and doorplate number of the
equipment room
2.
Equipment room type: Check the equipment room building to see it is civil building
or office building. Usually a civil building is not suitable for an iBSC equipment room
for two reasons. One is the residents do not have enough knowledge of
communication facilities and they may damage outdoor facilities by mistaken. The
other is the floor load bearing of the civil building usually does not meet the
installation requirements of the equipment.

Note: About the Floating Charge Mode
As a supply (discharging) mode of the storage battery, floating charge involves the storage
battery and power cable to be connected to the load circuit in parallel. When the battery is
fully charged, the charger will not stop working but still provide the floating charge voltage
ZTE Confidential Proprietary

18
ZXG10 iBSC (V8.00.00) Project Survey Guide

and minimal floating charge current to the storage battery. Once the charger stops working,
the storage battery will naturally discharge, so floating charge is used to counteract such
natural discharging, so that the storage battery always stays fully charged instead of over
discharged. Therefore, the storage battery is charged or discharged as the voltage on the
power cable fluctuates. When the load is light while the power voltage is high, the storage
battery is charged. When the load is heavy or the power supply is accidentally interrupted,
the storage battery is discharged to take over some or all of the load. In this way, the storage
battery serves to stabilize the voltage and keeps the backup state.
Note: About the Power Supply Mode
Class I power supply mode: establish an interruptible power supply system;
Class II power supply mode: establish a power supply system with backup;
Class II power supply mode: power supply for common users

Core Diameter of Power Cable
The core diameter of power cables can be calculated on the basis of the normal power
consumption of equipment, which is described as below:
1.
The core diameter of power cable is almost not related to the distance. But the
resistance will increase if the power cable is too long, and consequently the voltage
will decrease greatly. So, the core diameter shall be increased to reduce the
resistance of the power cable, and make the voltage drop less accordingly.
2.
The core diameter of the power cable relates to the magnitude of current that flows
over it. The algorithm for their relationship is complicated, and the following empiric
value is often used:
L = 1.15 × (I/a) 0.5
L is the diameter of the power cable in mm.
I is the current that flows over it, in amperes.
a is the empiric value, which usually ranges from 3 to 2.5.
Calculate the current with the following formula:
I=P/U
Among,
I — the current that flows over it, in amperes (A)
P — the power of equipment, in watts (W), calculated upon the maximum normal power
U — the voltages of the equipment (V)
The following results are acquired based on the above formula:
The value of long-term current that flows over a 1 mm 2 power cable is 3A-5A, but the
transient value may be larger;
Power cables of 2-3 mm2 are recommended for the current of 10A;
Power cables of 5-6 mm2 are recommended for the current of 20A;
Power cables of 10-12 mm2 are recommended for the current of 30A;
Power cables of 120-150 mm2 are recommended for the current of 300 A;
Power cables of 170-200 mm2 are recommended for the current of 500 A;
Power cables of 350 mm 2 or above are recommended for the current of 1000 A;

arrester and the outdoor grounding copper busbar.
4.2.4.2
Length and Quantity of Grounding Cable
Ascertain the distance between equipment and grounding copper busbar, and measure
the length of grounding cable as per its route. The measure tape or range finder is used
to measure along the route. Please refer to the user’s manual of range finder. Where site
condition is not ready for measurement (for example, the equipment is not installed or no
tape measure/range finder is available), visually measure them or use the empirical
value. The measurement method adopted shall be indicated in the survey table.
The quantity of grounding cables matches that of the equipment. The protection
grounding cable and the lightning prevention grounding cable shall be measured
separately.
4.2.4.3
Core Diameter and Color of Grounding Cable
The grounding cables of iBSC equipment are of the same specification. The protection
grounding cable is the 35mm 2 multi-core copper cable in yellowish green.
