“…Here, we select a business case that is detailed in the following: Main actors: An existing mobile network operator (MNO) who has a strong incentive to offer significantly higher capacity to satisfy their customer's demands in indoor and hotspots locations. We consider the MNO in this study based on the argument in that a new entrant does not have a competitive edge over the existing MNO for deploying in shared spectrum. Problem: The MNO needs a solution that offers the best cost‐performance trade‐off because it has already been challenged by the revenue gap that refers to a discrepancy between soaring mobile data demand and dwindling revenue increase. Value proposition: Mobile broadband communications in the radar bands offloading traffic demands in indoor and hotspot environments where the volume is extremely high. …”

“…We can find substantial literature that studied individual aspects of vertical spectrum sharing: technical, regulatory and business aspects. For example, fundamental limits of the vertical sharing were investigated in , the regulatory and policy aspects were discussed in and the business side was looked into in . However, it is difficult to find a cross‐boundary study.…”

The need to meet users' expectations in the "mobile data avalanche" represents a significant challenge for mobile networks operators (MNOs). More spectrum is a natural way to meet these requirements in a cost and time-efficient way; but new, exclusively licensed, spectrum is increasingly hard to come by. Instead, vertical spectrum sharing has been discussed as a potential solution for finding additional spectrum for mobile communications. In this paper, we focus on vertical spectrum sharing in the radar bands for providing short-range wireless access, e.g. indoors and in "hotspots" that "offload" mobile traffic demand. We propose a methodology for dealing with the technical, regulatory and business aspects of deploying large-scale wireless networks. Moreover, we identify the following criteria for achieving business success: spectrum availability, availability of low-cost enduser devices, system scalability in terms of number of concurrently used devices and finally, the ability to guarantee a quality of service for the users.Our technical availability assessment has identified geo-location database support as necessary technical enabler and detect-and-avoid mechanism as a beneficial technical enabler for improving sharing conditions. Therefore, we propose a * Corresponding author: Dr. Ki Won Sung (sungkw@kth.se) Preprint submitted to Telecommunications PolicyMay 6, 2014sharing mechanism based on three components: a central spectrum manager with a geo-location database controlling the aggregate interference, a spectrum sensing mechanism and a fast feedback between the radars and the central spectrum manager. Moreover, Licensed Shared Access (LSA) was found to be the suitable regulatory framework to support the proposed sharing mechanism and regulatory policies in real-life implementation.Our business feasibility assessment concludes that there is enough spectrum available for indoor and hotspots communication in urban areas in the radar bands to make a large scale system commercially viable. Service quality can be guaranteed and there is a strong potential to construct low-cost devices. Uncertainties do, however, remain regarding the spectrum access cost.

“…No matter the cost-capacity performance of CR equipment, a new operator needs to invest in a new infrastructure with sites and transmission. Only for cases where the spectrum costs are ''high'' (compared to other cost components) use of TW white spaces turn out to be more cost efficient for both existing operators and new operators [87].…”

This chapter turns to evaluation of techno-economic aspects of CR development and regulation, considering both the attractiveness of existing regulatory frameworks and the benefits of creating the new ones. This is important since it may be shown that the regulatory framework may have significant impact on economic benefits and viability of CR market adoption. Section 4.1 offers discussion of the potential for new business cases centred on the use of white space spectrum in the context of cellular networks. Section 4.2 is focusing on business scenarios and models for use of GDBs in TV white spaces. The following Sect. 4.3 provides a primer regarding the dynamics of the wireless communication market and how these can strongly influence the success or failure of a new technology. Section 4.4 considers potential business scenarios for spectrum sensing based on a set of parameters-ownership, exclusivity, tradability and neutrality. Section 4.5 looks at the prospects of business case for CR against the uncertainties of the spectrum market and opportunistic spectrum access circumstances. The chapter is concluded with the techno-economic analysis and case study in Sect. 4.6 that contemplates economic value of CR and secondary access. This builds a solid basis for answering the ultimate questions about business viability of CR, including considerations of cost versus capacity, investments, uncertainty and risk.
