The cellular phone network has been increasing rapidly during the last years. For many people the mobile phone has become an every day gadget with a wide performance and functional range. The usage of technologies like GPRS, HSCSD, EDGE and UMTS as well as the bandwidth of networks and conse quently the connectivity of the phones has also increased persistently. Co ming along with that, three technologies, which are ubiquitous or pervasive com puting, mobile and wireless networks and location-based technologies, are making rapid progress. The aim of this book is to offer an architecture for a context-aware user interface in the intersection of the three technologies men tioned above. The system should work with a minimum of special hard ware requirement. Not to overload the user with information, the user inter face should be adaptable, context-aware and location-based. The context-data should remain extendible and adaptable.
