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 all time and
anywhere connectivity
 Bring computer
communications to areas
without pre-existing
infrastructure
 Enable mobility
 Enable new applications
 An exciting new research
area

5. Principles of Mobile Computing
•Portability
•Interactivity
•Connectivity
•Individuality

6. Comparison to Wired Network
Wired Networks Mobile Networks
 high bandwidth
 low bandwidth variability
 can listen on wire
 high power machines
 high resource machines
 need physical
access(security)
 low delay
 connected operation
 low bandwidth
 high bandwidth variability
 hidden terminal problem
 low power machines
 low resource machines
 need proximity
 higher delay
 disconnected operation

7. Different Wireless Devices
Palmtop Laptops Cell phones
SensorsPagersPDAs

8. Applications of Mobile Computing
•For Estate Agents
•In Courts
•In Companies
•Stock Information
Collection
•Credit Card
Verification
•Electronic Mail

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

10. Future of Mobile Computing
 Use of Artificial
Intelligence
 Compact Size
Integrated
Circuitry
 Increases in
Computer
Processor speeds

11. Conclusion
 Mobile computing has
severe limitations
- however, it is far from
impossible, and
technology improves all
the time
 Lots of challenges
- some have (good)
solutions, many others
are still waiting to be
solved
