MOBILE COMPUTING

▪ Mobile computing is a technology that allows
transmission of data, voice and video via a computer or any
other wireless enabled device without having to be
connected to a fixed physical link.

2.1.1 SHOW mobile computing aspect

(Mobile Communication, Mobile Hardware, Mobile Software)

MOBILE COMPUTING ASPECT:

▪ Mobile communication
▪ Mobile hardware
▪ Mobile software

MOBILE COMMUNICATION

▪ The mobile communication refers to the infrastructure
put in place to ensure that seamless and reliable
communication goes on.

▪ Include devices such as protocols, services,
bandwidth, and portals necessary to facilitate and
support the stated services.

▪ This ensures that there is no collision with other
existing systems which offer the same service.

▪ A form of technology-mediated communication that
enables the user of a mobile device to communicate
with someone in a different location, for example,
texting from a cell phone and sending email from a
WiFi-equipped computer device (e.g., laptop, iPad).

MOBILE COMMUNICATION

▪ Since the media is unguided/unbounded, the overlaying
infrastructure is basically radio wave-oriented.

▪ That is, the signals are carried over the air to intended devices that
are capable of receiving and sending similar kinds of signals.

▪ Types of mobile communication systems are:

a. Mobile two-way radio
b. Public land radio
c. Mobile telephone
d. Amateur radio

MOBILE HARDWARE

▪ The second aspect is on the hardware, e.g., mobile devices or device
components.

▪ Mobile hardware includes mobile devices or device components that receive
or access the service of mobility.

▪ An electronic device which its user can easily carry.
▪ They would range from portable laptops, smartphones, tablet Pc's, Personal

Digital Assistants (PDA).

MOBILE HARDWARE

▪ These devices will have a receptor medium that is capable of sensing
and receiving signals.

▪ These devices are configured to operate in full- duplex, whereby they
are capable of sending and receiving signals at the same time.

▪ They don't have to wait until one device has finished communicating
for the other device to initiate communications.

▪ Above mentioned devices use an existing and established network to
operate on. In most cases, it would be a wireless network.

MOBILE SOFTWARE

▪ The third aspect deals with the characteristics and requirements of
mobile applications.-computer program.

▪ Mobile software is the actual program that runs on the mobile
hardware (phone, tablet or watch).

▪ It deals with the characteristics and requirements of mobile
applications.

▪ This is the engine of the mobile device. In other terms, it is the
operating system of the appliance.

▪ It's the essential component that operates the mobile device.

MOBILE SOFTWARE

▪ System software referred to OS such as iOS, Android, Window
Mobile and symbianOS.

▪ Application software referred to mobile application category, such as
Gaming Apps, Business Apps, Social Media Apps, Music Apps,
Messaging and Shopping.

▪ Examples of Gaming Apps, Business Apps, Social Media Apps, Music
Apps, Messaging and Shopping Apps.

2.1.2 STATES mobile computing
EVOLUTION

EVOLUTION OF MOBILE COMPUTING

▪ The idea of mobile computing has only been around since the 1990s.

▪ Evolved from two ways radios that use large antennas to communicate simple
messages to three inch personal computers that can do almost everything a
regular computer does.

▪ Radio transmitters that operated on a stable base the help of large antennas.

▪ People can connect wirelessly to the internet or to a private network anywhere.

▪ A person has one of the devices capable of wirelessly accessing the internet.

▪ Participating in mobile computing able use a laptop computer or a personal
digital assistant or PDA.

▪ So they decided to come up with an idea of portable devices.

EVOLUTION OF MOBILE COMPUTING

▪ Pocket PCs are another way to conveniently access the internet on
the earth devices that have been developed for mobile computing
has taken over the wireless industry.

▪ This new type of communication is a very powerful tool for both
businesses and personal use.

▪ The portable computer has change computing world to hundred
years’ back.

▪ It offers the opportunity to bring people together and give everyone
access to a greater wealth of information and knowledge, and to
share their knowledge with others.

EVOLUTION OF MOBILE COMPUTING

▪ Mobile computing is not only
limited to mobile phones.

▪ Various gadgets available in the
markets are built on a platform to
support mobile computing.
