Ongoing fifth generation mobile network 5G deployment is bringing higher speeds, higher capacity, lower latency and greater reliability into connectivity enabling data sharing amongst participating components of industrial systems. The private industrial network opportunity for serving different verticals is largely dependent on the timely availability, quality and the cost of spectrum. The growing pressure to open the wireless market for location specific networks has resulted in new regional licensing and sharingbased models for spectrum management. This paper discusses private industrial network requirements for the spectrum management through a framework that can be used to assess the feasibility of the spectrum management approaches. Specifically, recent sharing concepts above 5 GHz in the US, Europe and four selected countries: Australia, Hong Kong, Japan and UK are analyzed from the viewpoint of private industrial networks. Each of the selected sharing concepts is a unique approach to make wideband spectrum available for other network providers than traditional MNO's.

Spectrum deployment scenarios and advanced functionalities development in WINNER.) project is a major European research activity to develop a flexible and scalable radio access system for 4G, which is addressing the challenging requirements for future systems such as those of the International Telecommunication Union (ITU) in terms of overall performance, flexibility, scalability and optimized spectrum usage. In this article, the Radio Resource Management (RRM) spectrum functionalities are defined and subsequently analyzed. The proposed RRM spectrum architecture developed will result in reducing the time required to tailor new services to network operators. Furthermore, the flexible spectrum access and usage leads to more capable and faster services with high Quality-of-Service (QoS) giving more user satisfaction than conventional networks. The inherent centralization and decentralization degree for the functionalities is outlined and

The popularity of the smartphone and the resulting increase in the volume of wireless data traffic has created a large gap between bandwidth supply and demand. An attractive and less expensive solution to re-farming of spectrum is to maximize the use of under-utilized bands through spectrum sharing. Recent efforts in this area, that propose operation of wireless systems in shared spectrum, address the main challenge of how shared spectrum access systems can efficiently share and utilize spectrum resources. In this paper, we focus on the framework for multi-tier shared spectrum operation in wireless networks, where multiple entities -the Shared Spectrum Managers (SSMs) -dynamically acquire, manage and sell shared spectrum. We derive an auction based spectrum resource assignment algorithm which maximizes the overall system efficiency and provides incentives to the incumbents to make spectrum available for sharing. We demonstrate that the algorithm can be implemented in practice through messaging in which the SSM dynamically negotiates spectrum bidding and asking prices with the shared spectrum users. Simulations are performed under different scenarios and assumptions both to verify that the algorithm achieves the maximum utility value for shared spectrum systems, and to compare the outcome behavior under each scenario. Based on the observations, potential regulations that would need to be put in place in each scenario are discussed, and a set of future development areas are identified based on these observations.

New spectrum bands are being released to respond to the growing need for locally deployed industrial and private networks. This calls for new licensing schemes and spectrum sharing approaches. New challenges are faced from the ever-increasing variety of released spectrum bands with different technical and operational requirements and the increasing fragmentation of spectrum management approaches. While the standardization is progressing and technical solutions are developed for the new networks, less attention has been paid to the radio product related regulation, including equipment authorization frameworks. With roots in engineering, policy and economics, this paper looks through the lenses of business model framework at scenarios of wireless equipment authorization related to novel spectrum management approaches. This paper provides an overview of radio authorization for mobile communication networks and develops a conceptual framework to depict and analyze authorization policies. The results indicate the strong impact the authorization frameworks have on the scalability and replicability of the business. This calls for novel models of governance and regulation that highlight utilization of harmonized, widely employed frequency bands and the associated technical requirements.
