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 Access Each user on a different

frequency A channel is a frequency

TDMA-- Time Division Multiple Access

Each user on a different window period in time (which is called “time-slot”)

A channel is a specific time slot on a specific frequency

CDMA-- Code Division Multiple Access

A channel is a unique code pattern

Each user uses the same frequency all the time, but mixed with different distinguishing code patterns Frequency

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.


Public Lands Mobile Network (PLMN) has gone through 3 stages:

1. First Generation ----Analog Mobile Telephone System 2. Second Generation----Digital Mobile Communications

3G -- IMT-2000 (UMTS)

3. The third generation mobile communications —— Universal Mobile Telecommunication System

IMT-2000 (UMTS) 1) Features:

code division multiple access (CDMA) digital signal broadband

2) Meaning of ‘2000’ : frequency spectrum around 2000MHz data rate up to 2000kbps putting 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 important application of

the combination of mobile communication and Internet. The feature of 3G is the transmission capability of

providing data service in high rate.

Multiple Services

The Goal of 3G

Higher transmit rate Rich and colorful service Good voice quality Larger capacity Lower cost Good secret performance High frequency efficiency Easy to transition from 2G

Data Rate of IMT-2000

Voice 4.75Kb/s -- 12.2Kb/s
