A system overview of U-Net

Be a professional radio network design tool for 3G, completely

support GSM/TDMA,GPRS-EDGE, cdmaOne,W-CDMA / UMTS and

CDMA 2000/1x RTT/EVDO

Realize mobility of planning design, supporting a wide range of

project applications, single-processor configurations, and

Enterprise server-based network configurations. The single-

processor version does not requiring connecting external

database and users can still share engineering data.

Open, expandable platform

Friendly interface and be easy to install, operate, tune models

and generate reports

Modules in U-Net

Modular structure

Modular including :the basic core module, 3G module, measurement module, AFP (Automatic frequency

planning) module and microwave module

Select different modules based on demands

Requirement of U-Net

Software and hardware requirements for U-Net:

U-Net work station

• PC Pentium 3 processor or better.

• More than 256 MB memory. 512 MB memory is suggested.

• Windows NT 4.0/Windows 2000 Professional/Windows XP

U-Net single-processor version needn’t external database

Multi-user configurations supports the following database manag

ement systems (unsuitable for single user)

• Microsoft Access 97/2000

• Microsoft SQL Server 7.0

• Oracle v8.1.7 or higher

• Sybase Adaptive Server V 11.5

• World coordinates system database

- Support 1000+ kinds coordinates

- New coordinates system can be easily added in

• Integrated with other GIS tool, for exa

mple, MapInfo, and Arcview

- Import: Geographical data, traffic/population den

sity map

- Export: Coverage prediction map, vector data a

nd polygon

GIS Functions

GIS Functions

Support high-resolution map

Supported resolutions up to 1-metre precision

Support various map types Digital Elevation Model (DEM)

Clutter data (type and height)

Three-dimensional building data (raster and vector)

Traffic data or population density data

Satellite and navigation map

U-Net Propagation Model

Industry standard propagation models Okumura-Hata and Cost-Hata

Standard Propagation Model (SPM)

ITU 526-5 and ITU 370-7 propagation model

Longley-Rice and WLL propagation model

Advanced propagation calculation engine

Support third-party propagation models,

such as, Wavesight, Volcano, and Winpro.

U-Net Propagation Model

Dual-resolution pathloss matrix

Two pathloss matrices per transmitter

Propagation model, resolution and calculation

radius definable at pathloss matrix level

Benefits

Accuracy near transmitter (high resolution)

Calculation time and disk space optimization far

from transmitter (lower resolution)

TransmitterArea calculated

using a macrocellmodel

Area calculatedusing a

microcell model

Measurement Module

Import of CW measurement data

•Import and display CW data•Automatically correct the propagation model according to CW measurement• Prediction/measurement comparison, analysis

Import of measurement data of drive test

• Import, display and analyze testing mobile data• Playback on the map according to user-defined routes• Analyze and display call events•Automatically correct the propagation model according to drive test data•Prediction/measurement comparison, analysis

Traffic mapTraffic map

Purpose of traffic map

Distribute some mobiles to digital map.

Ways to create a traffic map

Traffic raster maps based on environments

Traffic vector maps based on user profiles

Traffic map based on transmitters and services

Traffic raster maps based on environmentsTraffic raster maps based on environments

Each raster of the map is assigned an environment class

Traffic map is created based on combination of environment

class ,user profile, user density and mobility

Environment class AEnvironment class A

• User profile A1, mobility User profile A1, mobility type A1, density A1type A1, density A1

• User profile A2, mobility User profile A2, mobility type A2, density A2type A2, density A2

Environment class BEnvironment class B

• User profile B1, mobility User profile B1, mobility type B1, density B1type B1, density B1

• User profile B2, mobility User profile B2, mobility type B2, density B2type B2, density B2

Traffic vector maps based on user profilesTraffic vector maps based on user profiles

Each polygon or line contains a density of subscribers with

given user profile and mobility types
