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
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

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
