A broadband, low-cost communication infrastructure based on the Internet, hotspots, and wireless LAN environments is becoming a reality. Moreover, terminals such as cellular phones and Personal Digital Assistants (PDAs) are evolving very quickly. Against this background, a ubiquitous environment that can be accessed at anytime and anywhere through various kinds of terminals is being constructed. However, because of the fast pace of change, it costs service providers a lot of time and money to provide high-quality services to users, and new technological developments are needed to solve this problem. This paper describes the technology requirements for achieving a ubiquitous environment and a Fujitsu middleware product called Realtime Communicator that can meet them. Then, this paper describes two typical applications of this middleware.
