There is increasing interest in the application of ubiquitous computing concepts to the use of mobile and wireless technologies in business. This paper presents the results of a conceptual study of the literature in ubiquitous and mobile computing and related areas. The outcome of the conceptual study is a context model of an identified Mobile Work Domain (MWD) which is focussed on mobile commerce and the use of new technologies and approaches to business processes in the workplace. This framework and context model comprises existing domains of activity and research, including electronic commerce, computer mediated communication and computer supported collaborative work and the new domains emerging from the relationships between these domains. Specific issues regarding mobile business are also identified and discussed including work domains, usability, context, software and infrastructure.
