At the School of Information Technology KMUTT we believe that information te- nology is the
most important driver of economy and social development. IT can - able better productivity as
well as helping us to save resources. IT is giving rise to a new round of industrial and
business revolution. We now can have products and s- vices that once were believed to be beyond
reach. Without IT it is impossible for people to realize their full potential. Businesses
worldwide are harnessing the power of broadband communication which will have a profound and
constructive impact on the economic social devel- ment education and almost all aspects of
our life. This new era of unified commu- cation presents us with new challenges. This is why we
should work together more closely to enhance the exchange of knowledge related to effective
application of broadband communication and IT. It is my sincere hope that all contributions to
the Third International Conference on Advances in Information Technology (IAIT 2009) will
increase our understanding of how we can have effectively apply this emerging technology for
the benefit of all people all around the world. I hope IAIT 2009 will also lead to more
research that can contr- ute to a better methodology for IT applications in the era of unified
communication. I am very grateful to all our keynotes speakers for coming all the way to
Thailand.
