The mobile system has been taking an important role as the infrastructure of the advanced information society. First, as the telecommunication infrastructure, it enabled us to communicate with anybody, anytime, and anywhere. Next, as the multimedia infrastructure, it enabled us to send, receive, and retrieve data. Now, as the IT infrastructure, it enables us to purchase commodities, transact business, and enjoy entertainment on-line. The mobile system has morphed into the third generation in almost two decades. Several mobile services have been introduced in each generation to feature the above infrastructures. This paper describes the authors' views on how mobile services have contributed to the advance of the information society in the past three generations. It also discusses what role the future mobile system should take in realizing the wealthier information society.
