2. Mobile technology is the technology used for
cellular communication. Mobile code division
multiple access (CDMA) technology has evolved
rapidly over the past few years. Since the start of this
millennium, a standard mobile device has gone from
being no more than a simple two-way pager to being
a mobile phone ,GPS navigation device , an
embedded web browser and instant messaging
client, and a handheld game console. Many experts
argue that the future of computer technology rests
in mobile computingwith wireless networking. Mobile
computing by way of tablet computers are becoming
more popular. Tablets are available on the 3G and
4G networks.

3. 3G
• 3G, short for third Generation, is the third generation
of mobile telecommunications technology.
• 3G telecommunication networks support services that
provide an information transfer rate of at least
200 kbit/s. Later 3G releases, often
denoted 3.5G and 3.75G, also provide mobile
broadband access of several Mbit/s to smartphones
and mobile modems in laptop computers.
• 3G finds application in wireless voice telephony, mobile
Internet access, fixed wireless Internet access, video
calls and mobile TV.

4. 4G
• In telecommunication systems, 4G is the fourth generation of mobile phone
mobile communicationtechnology standards. It is a successor to the third
generation (3G) standards. A 4G system provides mobile ultra-broadband Internet
access, for example to laptops with USB wireless modems to smartphones, and to
other mobile devices. Conceivable applications include amendedmobile
web access, IP telephony, gaming services, high-definition mobile TV, video
conferencing, 3D television, and cloud computing.
• Two 4G candidate systems are commercially deployed: the Mobile
WiMAX standard (first used in South Korea in 2006), and the first-release Long
Term Evolution (LTE) standard (in Oslo, Norway and Stockholm, Sweden since
2009). It has however been debated if these first-release versions should be
considered to be 4G or not, as discussed in the technical definition section below.
• In the United States, Sprint (previously Clearwire) has deployed Mobile WiMAX
networks since 2008, and MetroPCS was the first operator to offer LTE service in
2010. USB wireless modems have been available since the start, while WiMAX
smartphones have been available since 2010, and LTE smartphones since 2011.
Equipment made for different continents is not always compatible, because of
different frequency bands. Mobile WiMAX is currently (April 2012) not available
for the European market.

5. 5G
• 5G (5th generation mobile networks or 5th generation
wireless systems) is a term used in some research
papers and projects to denote the next major phase of
mobile telecommunications standards beyond the
current 4G/IMT-Advanceds tandards. 5G is also
referred to as beyond 2020 mobile communications
technologies. 5G does not describe any particular
specification in any official document published by any
telecommunication standardisation body.
• Although updated standards that define capabilities
beyond those defined in the current 4G standards are
under consideration, those new capabilities are still
being grouped under the current 4G standards.

6. Operating systems
Many types of mobile operating systems(OS) are available for smartphones,
including: Android, BlackBerry OS, webOS, iOS, Symbian, Windows Mobile
Professional (touch screen), Windows Mobile Standard (non-touch screen),
and Bada. Among the most popular are the Apple iPhone, and the newest -
Android. Android is a mobile operating system (OS) developed by Google.
Android is the first completely open source mobile OS, meaning that it is free
to any cell phone carrier. The Apple iPhone, which has several OSs like the
3G and 3G S, is the most popular smart phone at this time, because of its
customizable OS which you can use to download applications ("apps") made
by Apple like games, GPS, Utilities, and other tools. Any user can also create
their own Apps and publish them to Apple's App Store. The Palm Pre using
webOS has functionality over the Internet and can support Internet-based
programming languages such as Cascading Style Sheets(CSS), HTML,
and JavaScript. The Research In Motion (RIM) BlackBerry is a smartphone
with a multimedia player and third-party software installation. The Windows
Mobile Professional Smartphones (Pocket PC or Windows Mobile PDA) are
like that of a personal digital assistant(PDA) and have touchscreen abilities.
The Windows Mobile Standard does not have a touch screen but uses
a trackball, touchpad, rockers, etc.
The original smartphone OS is Symbian, with a rich history and the largest
marketshare until 2011. Although no single Symbian device has sold as
many units as the iPhone, Nokia and other manufacturers (currently
including Sony Ericsson and Samsung, and previously Motorola) release a
wide variety of Symbian models each year which gave Symbian the greatest
marketshare.
