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.

5/38

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 adedicated, private circuitthrough the transmission

medium, unaware that theother users exist.

Multiple Access: Simultaneous private use of a transmission mediumby 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

Basic Concepts of Communication---- Duplex

Why Duplex?

Separate Uplink 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 1980s 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.

Why we use 3G?

Limited frequency resource:

Present frequency cannot satisfy the need of mobile

communications 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.

In Oct.31, 2005, ZTEs WCDMA network at Brunei successfully passed the DSTs 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 ZTEs 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
