Basic Concepts of Communication----

Mobile Communication

Mobile communication is the communicationbetween 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.

7/27/2019 01 3G Overview-38



Multiple Access

Why Multiple Access?

Increased capacity: serve more users

Reduced capital requirements sincefewer 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 circuit

through the transmission

medium, unaware that the

other users exist.

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

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 specificfrequency

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 codepatterns

Basic Concepts of Communication---- Duplex

Why Duplex?

Separate Uplink and Downlink signals

Make sure the transmission to each endcan be fulfilled at the same time

Time Division Duplex (TDD)

Uplink and Downlink share the samefrequency

Frequency Division Duplex (FDD)

Uplink and Downlink use respectivefrequencies 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 anytime, and in any place.

7/27/2019 01 3G Overview-38



Public Land mobile communications system (PLMN)has gone through 3 stages:

1. First Generation ----Analog Mobile Telephone

System

2. Second Generation----Digital MobileCommunications System

3. Third Generation----IMT-2000

7/27/2019 01 3G Overview-38


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.

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.
