ABSTRACT
Mobile
computing is a new style of computer access emerging at the intersection of the
two currently dominant trends producing portable computers in computer industry
and wireless communications in telecommunication industry .this paper discusses
some key issues involved in realizing a mobile wireless computing environment
by examining the characteristics required of each main component .
Mobile computing has been undergoing a bit of
a renaissance lately. A few years ago it was a simple matter of finding a
data-compatible mobile phone, a PC card modem, and a matching cable and
installing it as a modem. Then people started to use PDA’s as well. Cell phones
started to come with infrared ports to allow communication with laptops. Then cell
phones started to come with modems built in. New and emerging mobile computing
applications are helping contractors, electricians and maintenance workers
Today’s mobile computing devices and
applications can do mobile job costing materials receiving ,electronic work orders,
control and alarm maintenance wire line or wireless.
The connecting methods of mobile computing,
its introduction, connection types, factors affecting connections, mobile
applications and its limitations are explained.
INTRODUCTION
Wireless networking
technology has engendered a new era of computing, called mobile computing.
Mobile Computing is an umbrella
term used to describe technologies that enable people to access network
services any place, anytime, and anywhere.
Ubiquitous computing and nomadic computing are
synonymous with mobile computing. Mobile computing helps users to
be productive immediately by reducing the training requirements associated with
traditional automated data collection methods and provides a higher level of
portability than keyboard-based systems.
Field-based users can
access any information available from the system at any time to make critical
business decisions. This information is available at the point of use, wherever
and whenever they need it.
Portable devices like
laptop and palm top computers give mobile users access to diverse sources of
global information anywhere and at any time.

CONCLUSION
Mobile computing is rapidly becoming
popular, and user demand for useful wireless applications is increasing. Additionally, this paper shows how these behavioral
extensions serve as a powerful abstraction for practical systems. In this paper;
we have looked at issues related to portable devices, merits, demerits and
applications in mobile environment. Because of the banes of mobile computing
the security level should be improved.
