Through the estimation, to perform a quantitative analysis and know the construction scale. Thus, the construction period and cost budget can be worked out.

• Scenario division and transmit mod

el confirmation• Quality of the capacity of scenario

s’ coverage• Traffic model and service model• Other related parameters• Estimation tool software• Related guide

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 the

company 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 m

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

• Scenario division and classification confirmation

• Selecting typical test points

• Testing instrument and

related software

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 network analysis 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 o

n the height.• It is recommended t

o mark the to-be recon

noitered on the paper

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 memo

Attention:• For proper sites, confirm the project parameters; for improper sites, give the replacing suggestion and verify the emulation• For sites cannot be reconnoitered caused by customers, sign the reconnaissance 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 selected site is available, you need to test on site by using electromagnetic interference device. Generally, the network planning reconnaissance personnel test it.

• Test instruments and fittings

• Related guide

•EM Interference Test Table•EM Background Test ReportOutput

Attention:• For experiment network

of 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 the

vehicles to test the road.

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

Retrospect of Radio Network Planning Flow


Case Analysis

A carrier bided for setting up a new radio network. Our company received the bidding 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 market strategy. 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.
