3. WHAT IS 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.

4. WHY GO MOBILE?
 Enable anywhere/anytime connectivity
 Bring computer communications to areas without pre-
existing infrastructure
 Enable mobility
 Enable new applications
 An exciting new research area

5. WIRELESS NETWORK
A wireless network is a computer network that uses
wireless data connections between network nodes.
 Wireless networking is a method by which
homes, telecommunications networks and business
installations avoid the costly process of introducing
cables into a building, or as a connection between
various equipment locations.

6. TYPES OF WIRELESS DEVICES
 Laptops
 Palmtops
 PDAs
 Cell phones
 Pagers
 Sensors

7. MOBILE OBJECTS
 Mobile objects, sometimes called mobile agents, are
bits of code that can move to another execution site
(presumably on a different machine) under their own
programmatic control, where they can then efficiently
interact with the local environment.
 Commercial instantiations of this technology include
Aglets from IBM, Concordia from Mitsubishi, and
Voyager from Object Space.

8. Moving Object Databases (MOD)
 Deals with Mobile Objects whose geometry, position
changes over time
 Traditional DBMS alone is incapable for this purpose
 MOD is built on top of existing DBMS to support a
critical set of capabilities.

9. COMPARISION
WIRED WIRELESS
 High bandwidth
 Low bandwidth variability
 Can listen on wire
 High power machines
 High resource machines
 Low delay
 Connected operation
 Low bandwidth
 High bandwidth variability
 Hidden terminal problem
 Low power machines
 Low resource machines
 High delay
 Disconnected operation

10. APPLICATIONS OF MOBILE
COMPUTING
 For Estate Agents
 In courts
 In companies
 Stock Information Collection/Control
 Credit Card Verification
 Taxi/Truck Dispatch
 Electronic Mail/Paging

11. Challenges
 Disconnection
 Low bandwidth
 High bandwidth variability
 Low power and resources
 Security risks
 Wide variety terminals and devices with different
capabilities
 Device attributes
 Fit more functionality into single, smaller device

12. ADVANTAGES
 Location Flexibility
Saves Time
Enhanced Productivity
Ease of Research
Entertainment
Streamlining of Business Processes

13. FUTURE OF MOBILE COMPUTING
 Use of Artificial Intelligence
 Integrated Circuitry -> Compact Size
 Increases in Computer Processor speeds

14. CONCLUSION
 Today's computing has rapidly grown from being confined
to a single location. With mobile computing, people can
work from the comfort of any location they wish to as long
as the connection and the security concerns are properly
factored. In the same light, the presence of high speed
connections has also promoted the use of mobile
computing.

Being an ever growing and emerging technology, mobile
computing will continue to be a core service in computing,
and Information and Communications Technology.
