It involves:
1. Mobile communication
2. Mobile hardware
3. Mobile software

3. Mobile communication
It refers to the
infrastructure put
in place to ensure
that seamless and
reliable
communication.
It includes:
 Protocols
 Services
 Bandwidth
 Portals etc…..

4. Mobile hardware
These devices will
have a receptor
medium that is
capable of sensing
and receiving
signals.
They would range
from:
 Portable laptops
 Smart phones
 Tablet pc’s
 Personal-digital

5. Mobile software:
 Mobile software is
the actual program
that runs on the
mobile hardware.
 It deals with the
characteristics and
requirements of
mobile applications.
 It enables users to
update documents,
surf the internet,
send and receive
email etc…..

6. What is mobile computing?
Aspects of mobility
– User mobility: users communicate “anytime,
anywhere, with anyone” .(example: read/write
email on web browser)
– Device portability: devices can be connected
anytime, anywhere to the Network. Examples are:
 The demand for mobile communication creates the
need for
 integration of wireless networks and existing fixed
networks
 Local area networks: standardization of IEEE
802.11 or HIPERLAN
 Wide area networks: GSM and ISDN

7. Principles of Mobile Computing
 Portability
Facilitates movement of device(s) within the
mobile computing environments.
 Connectivity
Ability to continuously stay connected with
minimal amount of lag/downtime, without being
affected by movements of the device.
 Social Interactivity
Maintaining the connectivity to collaborate
with other users, at least within the same
environment.
 Individuality

8. Devices of mobile computing
