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.
