Monitors the Following:Network input parameters, estimation RND documents and the result of the estimation.

The network estimation report needs to be reviewed.

Attention:

• When the parameters cannot be typed, refer to thecompany planning principle to provide values for the

carrier to confirm

• For improper parameters, communicate with and

guide the carrier on site. Besides, notify the

customer service center and market of the regional

office. The result need to be reviewed.






CW Test and Model Rectification (Optional)The transmit model is the basis of the cell planning. Whether the

model is correct affects the planning and affects whether the needs of theusers can be met in an economic and proper investment.

• Scenario division and

classification confirmation

• Selecting typical test points

• Testing instrument and

related software

• Related guide

•Adjusting Report of

Transmit ModelOutput

Attention:

• For years’ development,

the company has a complete

model library. It is

recommended to obtain the

model from the model library.

• For the needs of the market

or customers, you can test

the typical area based on the

actual reconnaissance. Then,

rectify the model based on

the test result.

003 Map Assistant Planning and Original Site Selection

Select and plan the area on the map based on the available site

resources of the carrier, destination coverage need, the carrier’s networkanalysis and network estimation result.

Attention:• Set the theoretic site

as the center and R/8

as the semidiameter to

search. Besides, there

are some restriction

on the height.

• It is recommended

to mark the to-be

reconnoitered on the

paper map.








004 Reconnoitering Base Station

Collect network planning information and environment

description to confirm whether the site meet the requirements

• Topology and map

of network base

stations

• Reconnaissance tool

• Related guide

Monitoring point:• The following needed to be reviewed: project parameter table,

base station topology, device setting, antenna feeder

• Check some base station reconnaissance

• Project parameter table

• Radio on site reconnaissance

report (xxx base station)

• On site reconnaissance table

• Base station reconnaissance me

Attention:• For proper sites, confirm the

project parameters; for improper sites,give the replacing suggestion andverify the emulation• For sites cannot be reconnoiteredcaused by customers, sign thereconnaissance memo• For sites have the same addresses,guarantee the independence• Factors of on site reconnaissance








Testing Electromagnetic Background (Optional)

To make sure that the electromagnetic background of the selectedsite is available, you need to test on site by using electromagneticinterference device. Generally, the network planning reconnaissancepersonnel test it.

• Test instruments

and fittings

• Related guide

•EM Interference Test Table

•EM Background Test ReportOutput

Attention:

• For experiment networkof large scale, you can

select and test sites based

on the actual work volume.

• The downlink band of

the area needs to be tested.

You need to arrange thevehicles to test the road.

005 System Emulation

Based on the previous information, you need to emulate the

system of the reconnoitered site. The emulation is a process to adjust

the planning configuration to meet the needs of the customers.

• Project parameter table

• Transmit model

• Parameters needed in emulation

• Emulation software

• Digital map• Related guide

XXX Project Network Emulation Report

Attention:

• When the theoretical site do not

meet the requirements, you need to

determine whether to select a new

site.

• When the emulation does not meet

the needs of the customer.

Reconnoiter and emulate the system

again to achieve the goal and export

the network emulation report.

Attention:

• The pre-planning report after

review needs to be submit to the

market of the regional office for

improvement. Then, it can be

submitted to the customer.

• When exporting the emulation

result, submitting the result in the

report template as soon as

possible to promote the progress

of the project.

Retrospect of Radio Network Planning Flow




Case Analysis

A carrier bided for setting up a new radio network. Our company received thebidding on Sep.24, and asked to on Oct.2. The market personnel sent the to a

network planning pre-sales engineer on Sep.29 and required them to complete

the pre-planning and post-planning of the network based on the bidding. The

pre-sales engineer found out that the traffic model condition and network

quality requirements are not clear. Besides, the on-site market personnel

cannot provide the correct information about the local geographical

environment, economy, population, mobile market, customer and marketstrategy. The pre-sales engineer finished the base station estimation and

network planning construction suggestions on Oct.2. The engineer made the

estimation of 45 base stations in the first period and 80 base stations in the

second period for the market to quote. The market personnel denied the

estimation and thought that the estimations do not accord with the actual

situation because the number of the base stations are too many, the pressure

of the service is heavy and the customers do not accept the estimation.Besides, the estimation does not adapt to the economy development of the

country and the actual situation of the customers is not taken into account. The

technical suggestions had not embody the network planning scheme.
