Introduction
Mobile Device?
A pocket-sized computing device, typically having a display
screen with touch input or a miniature keyboard
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.
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
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.
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
Stage Five1980's-
The Digital Mobile Communication
System(DMCS) gets developed and mature in
this period.
AMPS & TACS stand for the Cellular Networks

What is mobile operating system?
A mobile operating system, also known as a mobile OS, a mobile platform, or a handheld operating system, is the operating system that controls a mobile device or information appliance
Smartphone Operating Systems
The most common operating systems Symbian OS Symbian Foundation Android from Google Inc. iOS from Apple Inc. RIM BlackBerry OS Windows Mobile from Microsoft Linux operating system MeeGo from Nokia and Intel
Android 25.5% Market Share Sales
Q3 2010 Android is an open source,
Linux-derived platform backed by Google
along with major hardware and software developers (such as Intel, HTC, ARM, Samsung, Motorola and eBay
iOS 16.7% Market Share Sales
Q3 2010 The Apple iPhone,
iPod Touch and iPad all use an operating system
RIM BlackBerry OS

Nokia and Intel both
unveiled 'MeeGo' a brand new mobile operating system which would combine the best of Moblin and the best of Maemo to create a truly open-sourced experience for users across all devices.
Usage share of web client operating systems. (Source: Median values from Usage share of operating systems for January 2011.) Windows XP (41.70%)
Windows 7 (25.42%) Windows Vista (15.43%) Mac OS X (6.92%) iOS (iPhone) (2.05%) Linux (1.64%)
Future The mobile devices plays an indispensable role in nowa
day's life, meanwhile this field is still rapidly developing. More app is going to be added into.
In 2004 July 16, Japanese telephone company NTT DoCoMo announced the P605iC phone which carried the FeliCa soft. This phone opened the curtain of No Cards Generation.
Future Nowadays the manufactures of mobile devices are dev
oting on touching screen and 3D effect. More and more APP will be added into the mobile devic
es, make people's life much more convenient and fun.
