2. Mobile Computing
• Mobile Computing is a technology that provides an environment that
enables users to transmit data from one device to another device
without the use of any physical link or cables.
• In other words, you can say that mobile computing allows
transmission of data, voice and video via a computer or any other
wireless-enabled device without being connected to a fixed physical
link. In this technology, data transmission is done wirelessly with the
help of wireless devices such as mobiles, laptops etc.
• This is only because of Mobile Computing technology that you can
access and transmit data from any remote locations without being
present there physically. Mobile computing technology provides a
vast coverage diameter for communication. It is one of the fastest
and most reliable sectors of the computing technology field.

3. Mobile Computing
The concept of Mobile Computing can be divided
into three parts:
• Mobile Communication
• Mobile Hardware
• Mobile Software

4. Mobile Communication
• Mobile Communication specifies a framework that is
responsible for the working of mobile computing
technology. In this case, mobile communication refers to
an infrastructure that ensures seamless and reliable
communication among wireless devices. This framework
ensures the consistency and reliability of communication
between wireless devices. The mobile communication
framework consists of communication devices such as
protocols, services, bandwidth, and portals necessary to
facilitate and support the stated services. These devices
are responsible for delivering a smooth communication
process

5. Mobile communication can be divided in the
following four types:
• Fixed and Wired
• Fixed and Wireless
• Mobile and Wired
• Mobile and Wireless

6. Mobile Hardware
• Mobile hardware consists of mobile devices or device
components that can be used to receive or access the
service of mobility. Examples of mobile hardware can be
smart phones, laptops, portable PCs, tablet PCs, Personal
Digital Assistants, etc.
• These devices are inbuilt with a receptor medium that
can send and receive signals. These devices are capable
of operating in full-duplex. It means they can send and
receive signals at the same time. They don't have to wait
until one device has finished communicating for the
other device to initiate communications.

7. Mobile Software
• Mobile software is a program that runs on mobile
hardware. This is designed to deal capably with the
characteristics and requirements of mobile
applications. This is the operating system for the
appliance of mobile devices. In other words, you
can say it the heart of the mobile systems. This is
an essential component that operates the mobile
device.
• This provides portability to mobile devices, which
ensures wireless communication.

8. Applications of Mobile Computing
• Following is a list of some significant fields in
which mobile computing is generally applied:
• Web or Internet access.
• Global Position System (GPS).
• Emergency services.
• Entertainment services.
• Educational services.

9. Evolution
• Mobile computing can be categorized into seven
major categories of focus
• These categories are the basis for the technology
that is used today in research and design of
mobile computing
• Each category or section is a different area that
was focused on making mobile computing what it
is today
• These seven categories are: Portability,
Miniaturization, Connectivity, Convergence,
Divergence, Apps, Digital Ecosystems

10. Portability
• Reducing the size of hardware to enable the
creation of computers that could be physically
moved around relatively easily

11. Miniaturization
• Creating new and significantly smaller mobile
form factors that allowed the use of personal
mobile devices while on the move

12. Connectivity
• Developing devices and applications that
allowed users to be online and communicate
via wireless data networks while on the move

13. Convergence
• Integrating emerging types of digital mobile
devices, such as Personal Digital Assistants
(PDAs), mobile phones, music players,
cameras, games, etc., into hybrid devices

14. Divergence
• Opposite approach to interaction design by
promoting information appliances with
specialized functionality rather than
generalized ones

15. Applications (Apps)
•The latest wave of applications (apps) is about
developing matter and substance for use and
consumption on mobile devices, and making
access to this fun or functional interactive
application content easy and enjoyable

16. Digital Ecosystems
• The emerging wave of digital ecosystems is
about the larger wholes of pervasive and
interrelated technologies that interactive
mobile systems are increasingly becoming a
part of ecosystem.

17. Example: Smartphone
• Portability: carry it anywhere you want
• Miniaturization: make it possible to build device
to fit in your pocket
• Connectivity: Wi-Fi, LTE/4G, cellular, Bluetooth
• Convergence: phone, camera, gaming device,
movie streaming, music player, …
• Divergence: ?
• Applications: “Rise of the Apps”
• Digital Ecosystem: social networks, distributed
gaming, video streaming, work apps, …

18. App Store (iOS)
• 2003: iTunes Music Store
• 2008: iPhone App Store (iPhone 3G with App
Store support)
• 2015: > 100 billion app downloads
• 2016: > 2 million apps
• 2016: China biggest App Store market
• 2016: App developers earned $20 billions
• Most downloaded app: Minecraft Pocket Edition
(paid) and Pokemon GO (free)
