Although this perspective can be used more generally this paper deals with this perspective in the context of the alignment between the introduction of Cognitive Radio technology and the regulatory environment for the use of the radio spectrum. The value of this approach is demonstrated through a review of historical cases of changes in radio spectrum management and introduction of new (radio) technology. It proposes to use this approach to explore Use Cases within a Community of Practice as a possible way forward for coordination between the actors involved to allow successful deployment of cognitive radio and to realise the goal of improved utilisation of the radio spectrum.

The account covered the genesis of wireless local area networks (WLANs) in 1985 up to and including the mass market breakthrough with the Apple Airport in 1999 and the US$300 million marketing campaign by Intel for its Centrino chipsets with Wi-Fi Inside. Today, the road to global success continues with an unabated flow in new product capabilities, new applications, and increasing adoption. This contribution will capture the most recent part of the innovation journey of Wi-Fi and will explore the reasons for its current success using the original analytical framework. Moreover, it will look into future developments.The contribution starts with the recent developments in the IEEE 802.11 standardization arena and the product certification by the Wi-Fi Alliance, the two cornerstones of Wi-Fi development, enabling broad diffusion through low prices as a result of large economies of scale. We will explo...

Research paper thumbnail of Cognitive Radio: Enabling Technology in Need of Coordination

These CR capabilities are highly valuable for the introduction of new radio communication services, as all (usable) radio spectrum has been allocated and assigned, while in practice the spectrum appears to be under-utilized, considering time and place. However, the CR innovation journey is still in an early stage of unfolding. There is a large degree of uncertainty that will have to be mitigated before successful, large-scale deployment of the technology may be expected and the potential economic value can be realized. This contribution is aimed at identifying the instances of coordination that have led to successful deployment of new radio technologies in the past in an attempt to support the successful deployment of CR-based products and services in...

Research paper thumbnail of “Just Another Distribution Channel?”

This has resulted in a plethora of academic contributions on the design of new business models and service platform architectures. However, a discussion of the challenges that operators are facing in adopting these models is lacking. We assess these challenges by considering the mobile network as part of the value system of the content industry. We will argue that from the perspective of a content provider the mobile network is 'just another' distribution channel. Strategic options available for the mobile communication operators are to deliver an excellent distribution channel for content delivery or to move upwards in the value chain by becoming a content aggregator. To become a mobile content aggregator operators will have to develop or acquire complementary resources and capabilities. Whether this strategic option is sustainable remains open.

This affects all traditional infrastructure sectors including communications, energy, transport and water. This study highlights and illustrates some of the major challenges for readjusting the governance of network industries from an economic, institutional, political and technological perspective. The three parts of the book address the institutional design of infrastructures, the role of technology in different sectors and actor behaviour.

We discuss the UK case being inspired by the ideas of Coase. We discuss how an appropriate design of property rights and a secondary market would look like and how the developments after the introduction of property rights could be interpreted. Subsequently we present the alternative perspective of Commons to illuminate the implications of a Coasean perspective. It is shown how Coase's focus is on efficiency, whereas in the world of Commons, the societal value is central. We discuss how the two perspectives can contribute to the understanding of the governance of the radio spectrum and conclude with policy recommendations.

Because of large economic, cultural and political differences, the roads to realizing these ambitious goals are varying in between these Member States. This paper investigates the dynamics of fixed broadband markets in two neighboring regions: Flanders, the northern part of Belgium, and the Netherlands. The historical developments in telecom markets in both regions are highly similar and resulted in both areas in a duopoly between the incumbent, operating DSL on the former telephone network, and one or more cable operators, using the DOCSIS technology to offer broadband on the former analogue television network. However, in the race towards realizing the Digital Agenda goals, it comes down to the small differences in between both regions: the existence of housing organizations in the Netherlands has led to quite some Fiberto-the-Home deployment, whereas in Flanders, the traditional operators use evolutionary upgrades of both DSL and DOCSIS to realize the European targets.
