In this paper we examine the evolution and dynamics of value systems around GSM based mobile communications and Wi-Fi based wireless local area access. Drawing basis from value system modeling and systems thinking research a holistic framework, describing the underlying structures and dynamics of a value system at different stages and levels of service production, is created and used retrospectively to model the evolution of GSM based mobile communications and Wi-Fi based wireless local area access. The analysis based on the framework highlights that an important factor in the widespread diffusion of GSM and Wi-Fi has been the structural fit of the business and technology architectures as well as the alignment and synchronization of the different stages of service production and markets. The analysis also shows how the value systems around GSM and Wi-Fi follow distinctly different dynamics and evolution paths and how they are on a colliding course.

The application of Information and Communications Technologies (ICT) to mobility has produced a wide range of smart mobility services. These services have been deployed either as large, vertically integrated solutions driven by governments or as fragmented initiatives by competing companies and consortia. Lack of open approaches has restricted the diffusion of these services. In this paper we explore two possible paths for how the value systems around smart mobility services could transition from a closed model to an open model. We use a framework and two case examples from prior research [1] to study these transitions in either centralized or decentralized path. We aim to address the potential conflicts in the evolution of smart mobility services especially from the European perspective.

Service adoption strategies of push over cellular The original ideas for the framework came from both Ali-Vehmas and Luukkainen. Ali-Vehmas provided the initial case data while Luukkainen provided primarily theoretical contributions. Both Luukkainen and Ali-Vehmas further developed the journal article based on the initial joint conference paper in the International Conference of Mobile Business (ICMB'05) "Service diffusion strategies for push to talk over cellular", pp 427-433, 2005 presented by Ali-Vehmas. Publication II Evolution of wireless access provisioning: A systems thinking approach The original idea for the developed framework came from Ali-Vehmas. Casey conducted the interviews. Ali-Vehmas and Casey together further developed the framework and did the analysis. Ali-Vehmas and Casey together also wrote and edited the article. Publication III Complex network perspective to collaboration in the ICT standardization The original idea for the research came from Ali-Vehmas. Ali-Vehmas is the sole contributor of this article. Nokia Corporation provided the raw data sets. Publication IV Value system evolution toward a cognitive radio era: Implications of underlying market dynamics The article continued the work of Publication II. Casey developed the simulation model to which Ali-Vehmas provided comments. Casey and Ali-Vehmas together did the analysis. Casey wrote the first version of the article. Ali-Vehmas added text, further developed some of the conceptual ideas, and edited the article. Casey presented the paper in the IEEE 2012 DySPAN conference. Publication V Examining value system transitions: The case of smart mobility services The article is an application of the methodologies of Publications II and III in a qualitative analysis. Ali-Vehmas and Casey contributed to the case study. Ali-Vehmas further developed the detailed analysis. Ali-Vehmas and Casey wrote and edited the article. Ali-Vehmas presented the paper in the HICSS 48 conference. Research approach Concepts and methods developed for studying complex adaptive systems provide a compelling framework for the research on value systems with complexity. This thesis applies earlier conceptual models of complex systems to empirical ICT-driven value systems to develop a model for complex value systems, which can be used to examine behaviors of such systems. Empirical value systems

Standardization is a crucial enabler of global business of Information and Communications Technologies. Convergence of the underlying networking paradigms of licensed Mobile Communication and license exempted Internet has made progress but full integration is still far from being complete. For standardization professionals the unpredictable convergence makes decision-making and participation in standardization complicated. This study examines collaboration in five closely related standardization organizations working in this field during the years from 2003 to 2008. The results show similarities and differences in collaboration structures and behaviours reflecting the specific scope and context of each standardization organization. Furthermore, this study extends the use of social network analysis as a tool to the field of empirical standardization research. The results pave the way to better collaboration in standardization communities of converging Mobile Internet and beyond by providing better visibility and new insights to standardization leaders, policy makers and users.
