To analyse the evolution of the Swedish telecommunications sector (1970‐2003), with a focus on barriers and drivers of innovative activity.

Developing a functional approach to innovation systems analysis, where six basic interdependent functions need to be served for a new technology to be developed and diffused and for a supporting industry to evolve. The sector is divided into four major sub‐sectors: traditional fixed telecom; mobile telephony; fixed data communications (including internet); and mobile data communications (including mobile internet).

Relate to two questions: first, how did it happen that Sweden developed a leading innovation system for mobile telephony but not for data communication; and second, what are the strengths and weaknesses of the innovation system for mobile data communications? Findings include that early developments mattered, innovative search direction is crucial as are the provision of incentives for innovative activity.

Functional analysis of innovation systems useful for guiding policy actions, which should have the purpose of strengthening weak functions, removing bottlenecks and stimulating inducement mechanisms, in particular if used to stimulate the transition from one phase to another. It needs further development, in particular with respect to the understanding of diffusion processes.

The stimulation of innovation in, and diffusion of, mobile and broadband data services is crucial to development of the innovation system, globally, in Europe and in Sweden. An innovation system which allows for entrepreneurial experimentation should be fostered. Early stage financing and diffusion of services are major system weaknesses. Regulatory authorities should consider addressing innovation explicitly.

New (adapted) approach for guiding policy action. Better understanding of dynamics in the telecom sector, and the comparative success and failure of Swedish industry in sub‐sectors.

The paper investigates the evolution of the successful mobile internet service i‐mode in Japan, identifies the relevant explanatory factors, and provides implications for the further development of mobile data communications in Europe. In conclusion, the paper argues that there must be a balanced and efficient mix of industry coordination, service experimentation, and dynamic competition in order to provide a foundation for mobile data success in Europe.

This paper addresses the potential need for European public policy actions in the area of mobile communications, in particular of developments towards 4th generation networks (4G). The paper is based on work conducted for the EC/JRC/IPTS/ESTO project “The Future of Mobile Technologies in EU: Assessing 4G Developments”. The paper first reviews developments of 3G and 4G technologies in Japan, Korea, China and the USA. It briefly addresses potential costs and benefits of competition in infrastructures. The paper states that initiatives in Europe for technologies beyond 3G tend to address research issues, while players in Asia and the USA are aiming at sales of 4G‐equipment supposed to start as soon as possible. In conclusion, nine options for policy makers are presented, such as to stimulate 2.5G and 3G data markets, to analyse actual spectrum use, to continue analysing approaches competing with UMTS, to estimate costs and benefits of new approaches to spectrum regulation, and to evaluate steps towards frequency allocation.

The paper aims to explore two developing display technologies, organic light emitting diodes (OLEDs) and e‐paper, with a view to assessing their potential to disrupt existing markets and thereby offer an opportunity for European firms to play a larger role in the Information and communication technologies (ICTs) sector.

The paper is based on an extensive study including literature review and detailed desk research on the technologies themselves, their potential application and market analysis. Selected interviews with industry representatives were also carried out, which further informed a detailed value chain analysis and assessment of the EU position in these technologies.

OLEDs and e‐paper have the potential to disrupt current displays market and in so doing they may enable EU companies to enter at selected points in the value chain to compete with the Asian ICT industry.

Although there is a huge literature on the technical aspects of these technologies, speculative market analysis and journalistic assessments, this paper brings all of these facets together in a sophisticated value chain analysis that indicates opportunities for Europe's ICT sector.

The purpose of this paper is to introduce the papers in the special issue on “Next generation mobile telecommunications networks challenges to the Nordic ICT industries”.

This introductory paper summarises the key points of each paper.

The competitive environment of the Nordic ICT industries has changed and is far more complex now compared to the previous single‐standard environment of 2G. The avenues for influencing competition between basic technology platforms and standards are much narrower and involve interaction with a much greater number of stakeholders and technologies on a global level.

The six papers of this Special Issue highlight interesting viewpoints both on the possible future evolution of the mobile telecommunications industry in general, as well as on the past development and present challenges that the Nordic countries face.
