Introduction

Mobile Device?

A pocket-sized computing device, typically having a display

screen with touch input or a miniature keyboard

Page 4: Mobile devices ppt

historyIt can be said that the mobile devices was born at

the same time the radio communication had been invented.

The development of mobile devices starts from the 1920's, there are five stages.

Page 5: Mobile devices ppt

Stage One 1920's-1940'sBased on several wave bands of shortwave, the private mobile co

mmunication system had been invented.

The Detroit police car radio system is the representative one.

The frequency of this system is 2MHz at that time. In the 1940's the frequency had been risen to 30~40MHz.

It is considered as the beginning of the modern mobile service.

Stage Two1940's-1960's

The public mobile service came out.

1946 According to the plan of Federal Communications Commission(FCC) the Bell system established the first public car phone net in St.Louis.

There was three channles in that time, the mode was simplex.

Stage Three1960's-1970's

America improved the mobile telephony system(1MTS)

This period complete : automatic channel choose automatic dialing to the net

Page 8: Mobile devices ppt

Stage Four1970's-1980's( the peak time)

The Bell Labs successfully developed the advanced mobile phone system(AMPS)

The cellular network built up, improved the capacity of the system.

The cellular network becames the utility system, used in the worldwide.

Page 9: Mobile devices ppt

Stage FourAchivements in this stage:

microelectronic technique got a significant development which made the probability of miniaturization mobile devices be true.

The new system of mobile communication----cellular network

provide the technique for the manage and control of the large size net

Page 10: Mobile devices ppt

Stage Five1980's-

The Digital Mobile Communication

System(DMCS) gets developed and mature in

this period.

AMPS & TACS stand for the Cellular Networks
