1 Project Survey

1.1 Overview

1.1.1 Purpose of Survey

Project survey is an important step before project implementation, in which reliable

data is obtained to lay foundation for engineering design, network planning and future

project implementation. Specialists survey the project on the site to judge whether the

site is appropriate for constructing a base station and to adopt a construction scheme.

Scheme worked out on the site must be approved in all aspects, for example, whether

the construction cost is reasonable and whether the future coverage result agrees with

the pre-defined construction scheme.

In a word, without onsite survey of project, many construction methodologies are

groundless and cannot stand the test in practice. We must carry out survey on the site

for the purpose of obtaining all data we want.

1.1.2 Functions of Survey

Project survey serves to determine the subsequent construction scheme and obtain

reliable data. It has the following three functions:

1. To judge whether the site is appropriate for constructing a base station, and if it

is inappropriate, select another site as soon as possible.

2. To determine a preliminary construction scheme and obtain correct data for

engineering design and network planning later.

3. To predict the possible difficulties in future project implementation. For

example, to construct a new site at a scenery spot, we must make the base

station harmonious with ambient environment.

1.1.3 Principles for Survey

Survey should be performed in accordance with the specifications, and should have

clear results, with no ambiguous results allowed.


2

Survey should follow the principle of being practical and realistic, with no fraud and

data falsification allowed.

When the carrier puts forward any special requirements, our staff shall negotiate with

the carrier. Anything that cannot be determined should be timely reported to ZTE local

office.

Technical personnel of the carrier are required to participate in the survey process for

assistance and for monitoring the process and the results.

All survey items should be performed without missing and repetition.

Without prior permission from the appropriate personnel of the carrier, do not enter the

equipment room or check the equipment in it.

Safety issues should be attended to during the survey to avoid personal injury and

equipment damage.

1.1.4 Outputs of Survey

At the end of the project survey, the following reports should be completed:

1. ZXG10 B8018 (V1.00) Base Transceiver Station Project Survey Report

(Engineering Design Information)


(Commissioning Data)


(Production Scheduling and Delivery Data)

4. ZXG10 B8018 (V1.00) Base Transceiver Station Environment Acceptance

Report

Any problems such as configuration found during survey should be completed in

appropriate tables, for example, Contract Problem Feedback Table.

1.3 Environment Survey

1.3.1 Overview

The operation environment has great influence on network equipment. During

engineering design, first consider that a good operation environment can make the

equipment work perfectly. Do not set the equipment room in a place with high

temperature, inflammables, explosives, low voltage or harmful gases. Keep the

equipment room away from severe vibration, strong noise, step-down substations and

traction substations. In addition, auxiliary facilities of the equipment room (such as

power supply, lighting, ventilation, temperature control, grounding wire and iron tower)

will affect the installation, running, operation and maintenance of the equipment.

Therefore, during project survey, strictly check whether the equipment installation

environment meets the design standards and equipment running conditions.

Environment check is divided into two stages: Prior check and pre-installation check.

The prior check is conducted during project survey by ZTE survey engineers. The

check results must be recorded in the environment check table according to the facts.

Any parts that are not in compliance with the standards must be notified to the carrier

in written form. Ask the carrier to make corrections, and track such alterations all the

time. Pre-installation check is conducted by the Engineering Supervisor of ZTE

Corporation before installation. The check is to confirm the previous check results and

corrections to ensure that the installation environment meets the installation conditions,

to facilitate smooth installation. The pre-installation check belongs to installation, so no

further description will be given here. The installation environment check in this

document refers to the prior check.

Based on the equipment running features and requirements of the ZXG10 B8018

(V1.00) base transceiver station, the installation environment check covers the

following contents.

Core Diameter of Power Cables

Core diameter of power cables can be calculated according to the nominal power of

equipment.

The core diameter of power cable is not closely related to distance. The longer

the power cable, the larger its resistance and thus the larger the voltage drop.

You can increase the core diameter to decrease the resistance of the power

cables and reduce the voltage drop.

The core diameter of a power cable is closely related to the current that runs

through the power cable. The calculation is relatively complicated, and normally

the empiric value is used:

L = 1.15 (I/a) 0.5

In the formula, L is the diameter of power cable, in units of millimeters.

I is the current running through the cable, in units of amperes.


22

a is an empiric parameter ranging from 3 to 2.5.

The current can be calculated in the following formula: I=P/U

Where:

I: Current that runs through the power cable, in units of ampere (A)

P: Equipment power, in units of watt (W). The maximum nominal power is used here.

U: Voltage for the equipment, in units of volt (V).

The following result can be obtained based on the above formula:

The long-term current that can pass a power cable with a cross section area of one

square millimeter is 3A~5A, and the instantaneous current value can be more larger.

For a current of 10A, it is recommended that a power cable with a cross section area of

2 to 3 square millimeters be used.





For a current of 300A, it is recommended that a power cable with a cross section area

of 120 to 150 square millimeters be used.


of 170 to 200 square millimeters be used.


of 350 square millimeters or above be used.

Furthermore, the cable material is also very important. The above empiric value is only

based on a single strand of power cable. If multiple strands of power cables are used,

the core diameter must be enlarged accordingly.

1.4.2.6 Grounding Cables

Type of Grounding Cables

Protection grounding cable of equipment connects the equipment to the indoor

grounding copper busbar.

Lightning protection grounding cable connects the lightning arrestor and outdoor


23

grounding copper busbar.

Length and Quantity of Grounding Cables

Determine the distance between equipment and grounding copper busbar and measure

the length of grounding cable along its route with a tape measure. If the length cannot

be measured for any reason, for example, the equipment is not installed or there is no

tape measure, you can judge by your eyes or your experience. Measurement method

shall be indicated in the survey table.

The number of grounding cables is equal to the number of equipment. Note that the

protection grounding cable and the lightning protection grounding cable shall be

measured separately.

Core Diameter and Color of Grounding Cables

Grounding cable specifications for base station equipment of ZTE Corporation are

uniform: protection grounding cable is a yellow-green 35 mm2 cable of multiple copper

cores and lightning protection grounding cable is a black 25 mm2

cable of multiple

copper cores.

Auxiliary Facilities in Equipment Room

cabling rack data; otherwise, do not survey the cabling rack data, but write None" in

the length volume of survey table. Determine the length of cabling rack according to

the design drawing of equipment room. In addition, understand how to install the

cabling rack, suspend or support it. (ZTE Corporation defines uniform specifications

for indoor cabling racks, which are all 40 cm wide. Any special requirement must be

stated in the Remarks column.)

Feeder Window

For outdoor feeder to enter equipment room, a feeder window is needed. Survey the

number of holes of the feeder window, four, six or nine holes. If there are many

wireless equipment in an equipment room, consider relations between the number of

feeders and the feeder window.

Figure 1.4-6 Feeder Window 1

Outdoor Part of the Base Station

Survey the antenna feeder system, outdoor base station and auxiliary materials.

Length and Quantity of Feeders

Measure the feeder length between the antenna and equipment along its route with a

tape measure. If the length cannot be measured for any reason, for example, the

equipment is not installed or there is no tape measure, you can judge by your eyes or

your experience. For any place that requires high measurement accuracy, use an

infrared distance meter or height meter. For how to use the measure, please refer to the

user instructions.

Figure 1.4-7 Infrared Distance Meter

Determine the quantity of feeders according to equipment configuration, for example,

the number of cells and diversity reception.

Feeder Type

Feeder length determines the type of feeder to be used. For wireless equipment, feeder


25

length relates to the feeder diameter. For example, in base station equipment, if the

feeder length is within 80 m, the diameter shall be 7/8 inch; If the feeder length is more

than 80 m, the diameter shall be 5/4 inch.

Figure 1.4-8 Main Feeder Cable

A super flexible jumper (generally of 1/2 inch) shall be used between antenna and the

main feeder cable and between the main feeder cable and cabinet.
