In international comparisons the Nordic countries tend to stand out as major producers and users of information and communcation technology (ICT), especially in the field of mobile telecommunications. There is a common understanding the Nordic countries were particularly well-placed to enter the booming telecommunications industry of the 1980s due to a combination of advanced demand, institutional and societal set-ups that characterise these countries. But this e-book suggests that the technological and business setting of the Nordic mobile communications is undergoing fundamental changes with the potential to seriously disrupt the strong position of the Nordic ICT industries. The six papers highlight interesting viewpoints on the possible future evolution of the mobile telecommunications industry in general, as well as on the past development and current challenges facing the Nordic countries.
