This thesis analyses the role of the foreclosure or irreversibility towards TETRA deriving from the harmonization process and how the Danish state tackled this foregone TETRA conclusion, when the Danish authorities opted for a technology neutral public procurement both in 2000 and 2006. Many theorists are theorizing on foreclosures and lock in also called 'irreversibility and path creation towards a certain technology' development and trajectory and what impact it is has on the alternative new technologies and the development of the exiting technology. Everything emerges from an essentially historical dynamic process of contingent ordering, irreversibility, momentum and possible lock-in. Camilla Bonde have used an emperical study to explain those drivers and barriers in the decision making process in two public procurement processes on public safety and emergency networks and services in Denmark; The first part of the study regards the introduction of the TETRA technology in 2001, which was based on a technology neutral public procurement on public mobile licenses within the EU harmonized spectrum for PMR trunked digital land mobile standards adopted by ETSI designated for public safety and emergency service. The licensee holder, who gained the spectrum access and the public mobile license, was in consideration for the allocation obliged to roll-out a nationwide mobile infrastructure to provide a network, which contained public safety and emergency requirements and with priority to public safety and emergency users. The second part of the case study on the deployment of the TETRA technology concerns the later public procurement project in 2006 on the public safety and emergency service subscription contract, called "SINE" (SIkkerhedsNEt). It is called 'the TETRA development' because it was only actors with solutions based on TETRA technology that were pre-selected and qualified to fulfill the specification requirements made by the Danish state in the public procurement 2006 to compete on the subscription contract.
Some of the research questions are: What made the TETRA technology and not the TETRA standards irreversible in Denmark and how was it possible to make a technology neutral public procurement in a context with a foregone TETRA conclusion based on the EU harmonisation. How did the decision-makers in Denmark deal with this foregone conclusion or irreversibility towards a certain technology and what are the intended and unintended consequences of such irreversibility towards a technology for the technology development itself in Denmark, new technologies and the market? On what level does one see lock-in? This case study of the two procurements was guided by a great body of research that addresses knowledge of the relevant law, technology and drivers and barriers that are shaping technologies, especially with attention to MacKenzie and Wajcman. As my study also aimed to seek insightful knowledge of the mind-set of the key decision-makers too and now how they dealt with the dissonance between the political technology neutral and legal and technological technology dependencies using the theory of cognitive dissonance' by Leon Festinger.
