ZTE WCDMA Features

Basic Concepts of Communication----Mobile Communication

Mobile communication is the communication between

mobile bodies or that between mobile body and fixed

body. Mobile communication has some features

compared with fixed communication:

Mobility, keep communicating in the mobile state.

Complicated radio propagation conditions.

Heavy noise and interference.

Complicated system and network structure.

Efficiency utilization of bandwidth and good performance of

system are needed.

Basic Concepts of Communication----Multiple Access

Why Multiple Access?

Increased capacity: serve more users

Reduced capital requirements since fewer

media can carry the traffic

Decreased per-user expense

Types of Transmission Medium:

Twisted pair

Coaxial cable

Fiber optic cable

Air interface (radio signals)

Each pair of users enjoys a dedicated, private circuit through the transmission

medium, unaware that theother users exist.

Multiple Access: Simultaneous private use of a transmission medium by multiple, independent users.

Basic Concepts of Communication----Multiple Access

FDMA-- Frequency Division Multiple AccessEach user on a different frequencyA channel is a frequency

TDMA-- Time Division Multiple AccessEach user on a different window periodin time (which is called “time-slot”)A channel is a specific time slot on a specific frequency

CDMA-- Code Division Multiple AccessA channel is a unique code patternEach user uses the same frequency all the time, but mixed with different distinguishing code patterns

Basic Concepts of Communication---- Duplex

Why Duplex?

Separate Unlink and Downlink signals

Make sure the transmission to each end can be

fulfilled at the same time

Time Division Duplex (TDD)

Uplink and Downlink share the same frequency

Frequency Division Duplex (FDD)

Uplink and Downlink use respective frequencies

to fulfill the transmission


Evolution of Mobile Communications

Mobile communications existed half a century ago, but it

was in the 1980’s that it was really developed.

The main goal of mobile communications is to realize

communication among any objects at any time, and in

any place.

3. The third generation mobile communications

—— Universal Mobile Telecommunication SystemIMT-2000 (UMTS)

1) Features: code division multiple access (CDMA)digital signalbroadband

2) Meaning of ‘2000’ : frequency spectrum around 2000MHzdata rate up to 2000kbpsputting into business about year 2000

3) Representative Systems: WCDMA CDMA2000 TD-SCDMA


Why we use 3G?

Limited frequency resource:

Present frequency cannot satisfy the need of mobile

communication’s development.

The frequency efficiency of 2G is lower than that of 3G.

Need of mobile multi-media:

Mobile data service will be the necessary product

of the combination of mobile communication and Internet.

The feature of 3G is the transmission capability of

providing data service in high rate.

ZTE built up the commercial WCDMA network

in the capital Dushanbe and the second largest

city Khujand. 3G Subscriber can easily roam

between the two cities and inter-work with the

2G or fixed line network.

2G and 3G share the same core network with

150,000 capacity.

BruneiExcellent KPI Network

In Oct.31, 2005, ZTE’s WCDMA network at Brunei successfully passed the DST’s radio

performance and service test. It began to offer wholly 3G service and achieve 2G/3G access.

With only half of the schedule, ZTE finished the network construction and optimization, DST

highly commented ZTE’s efficiency in network construction “…we are very satisfied with the

speed and the good quality.”

ZTE achieved the theoretical maximum value in the online single cell test.

Brunei, is the third biggest oil product country

in southeast-asia and the fourth biggest natural

gas product country in the world.

DST, is the biggest mobile operator in Brunei

TunisWidely Recognized in High Value

ZTE gave a great and complete

support to the communication

system of the WSIS.

In this summit, the government

leaders, guests and visitors of

more than 70 countries enjoyed

the good services in voice, data

and multimedia by WCDMA

network which was constructed by

ZTE.
