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.
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.

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.
