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 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.

BruneiExcellent KPI Network
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
in southeast-asia and the fourth biggest natural
gas product country in the world.
