3 PREFACE This dissertation is completed with encouragement, ideas and ready assistance from all the committed people I have met. I extend my sincere gratitude to them for their tremendous service. Firstly, I wish to express my heartiest gratitude to supervisor, Dr. Chulantha E. Kulasekara, for his valuable advice and guidance throughout this study and willingness entrust so much of the development of the project to my judgment. Secondly, I wish to express my gratitude to engineers in the ADSL section of Sri Lanka Telecom, especially to Mr. Undugoda, for giving me valuable comments and participating in the survey. Finally, I wish to express my gratitude to all Internet Cafe owners, who responded to the opinion survey, on ADSL technology and the dial-up users for their responses to the survey. I further express my gratitude, to the ADSL users who participated in opinion survey. Sanath I Wanniarachchi 21 October 2005 ii

4 ABSTRACT This thesis contains the findings of my study in the area of ADSL technology and technology usage, user experience and development paths. In this exercise I have tried to validate the usability of Dr. Ramanathan's model of technology transfer in ADSL type of technology transfer. Further, my hypothesis, ADSL is the Internet superhighway for Sri Lanka, has been tested with the survey results at Internet Cafes, Dial-up users, and current users. A price, users willing to pay and bandwidth they require will also be derived at in this exercise. Further international status of ADSL technology usage and the supply chain analysis of the ADSL technology has been carried out to formulate the whole picture of the technology and to position Sri Lanka as a country in the technology usage. Case study method research will be adopted in this report to analyze the survey data iii
