The purpose of this paper is to propose technology-independent metrics for measuring spectrum utilization efficiency and spectrum sharing which could prove useful in spectrum management. Radio spectrum is considered a scarce resource. The rapid rise in all kinds of wireless devices emphasizes the need for spectrum usage efficiency and spectrum sharing. Notably in license exempt spectrum, the increased density of radio devices requires new methods of evaluating their performance.

The authors go back to the fundamentals of spectrum utilization and show that under high usage conditions, wireless network performance is interference limited. The impact of interference depends both on the environment and on the type of modulation used. The authors use these factors to derive the above metrics.

The main findings of this work are metrics for spectrum utilization and sharing that are technology-independent and therefore widely applicable, notably to license exempt spectrum. These metrics provide increased visibility of receiver performance in determining spectrum use. The authors also find that the capacity of a wireless network is for all practical purposes unlimited – provided the appropriate choices of the technical parameters are made, recognizing the impact of the propagation environment.

Because the authors proceed from simplifying assumptions, detailed analysis and prediction of spectrum-sharing cases may require additional parameters to be added to the equations given.

The results of this work have potential application in spectrum management and in the development of regulatory requirements for license exempt spectrum.

New in this paper is the derivation of spectrum utilization and sharing metrics from first principles that allow different technologies to be compared. The authors also show that, given the right choice of technical parameters, the capacity of wireless networks is practically unlimited.

The purpose of this paper is to investigate the possibility to replace radio equipment compliance requirements based on equipment parameters with a set of simple metrics that accurately reflects spectrum utilization and spectrum-sharing efficiency.

The approach taken is to go back to the basic factors that determine radio system behavior in a shared spectrum environment: radio frequency power, duty cycle and frequency occupation. By normalizing these parameters, device specificity is avoided and a statistical perspective on spectrum utilization and sharing becomes possible.

The analysis shows that two technology-neutral metrics would be adequate to govern spectrum utilization and sharing: a spectrum utilization metric and a spectrum-sharing efficiency metric. These metrics form the core of regulatory requirements for shared frequency bands. Each shared frequency band could be assigned criteria based on these metrics that take into account the types of applications for which that band will be used.

This work is a first step that identifies the main factors that affect shared spectrum usage from a statistical point of view. More work is needed on the relationship between real-world interference and its abstraction in the spectrum-sharing rules.

The metrics proposed could be considered as the basis for a new approach to the regulation of the license-exempt spectrum, and, by extension, as the basis for generic compliance criteria. Their use would facilitate the compliance assessment of software-defined radio technology.

This work has no direct social implications.

This paper combines new work on spectrum utilization criteria with extensions of previous work on spectrum-sharing efficiency into a comprehensive proposal for a new approach to the regulation of the license-exempt spectrum.

Spectrum regulations have major impact on the development and deployment of innovative technologies. Current regulations for license-exempt radio spectrum generally are given in terms of technology-related criteria. This paper aims to propose a set of metrics that can be used to define technology-agnostic spectrum regulations which encourage rather than restrict technology innovation.

This paper builds on and expands two other papers on regulatory criteria for license-exempt spectrum which define metrics for spectrum loading and spectrum sharing efficiency. Here, we add metrics for Block Edge Masks and for medium access adaptivity. This gives a complete toolset for the management of radio spectrum.

Because of the diversity of use of license-exempt spectrum, performance criteria must be formulated in terms that abstract from the details of equipment properties. Instead, they must be formulated in terms of spectrum utilization dimensions: RF power, time and frequency occupation. The result is a concise set of metrics that can be applied to the regulation or management of shared spectrum.

The mathematics used in this paper deal with high-level parameters and may ignore factors that are important in certain cases and may require refinement.

The implications of the proposed metrics include an increase emphasis on the objectives of spectrum policy and on measures to assure efficient spectrum utilization both within frequency bands and between adjacent bands.

There are no social implications the authors are aware of.

The originality of this work lies in recognizing that the extreme variety of devices and mode of operation deployed in license-exempt spectrum calls for spectrum management criteria that are technology agnostic.

The European telecommunications landscape has been transformed over the past 25 years, but spectrum management has remained largely unchanged. The paper seeks to highlight the need for a more flexible approach to spectrum management and, in particular, the role of shared spectrum access.

The paper draws on a research study to examine the value of shared spectrum access, based on a review of the literature, a survey of European national regulatory authorities, and scenario analysis.

The paper highlights trends in wireless data growth and, in particular, the impact of 4G cellular mobile technology over the next five years. With pressure also growing on the licence‐exempt bands at 2.4 and 5 GHz, a more flexible approach to spectrum management will be required in future, including light licensing, de‐licensing and spectrum sharing.

The paper brings together a range of evidence to show how the current approach to spectrum management is no longer able to cope with the social and economic demands for the radio spectrum. It should be of value to policy makers, industry analysts and academics.

5G systems will enable an improved transmission performance and the delivery of advanced communication services. To meet the expected requirements, operators will need to invest in network modernisation, with the radio access network being the most expensive network component. One possible way for operators to reduce this investment would be via sharing of resources by means of a multi-tenancy concept. This implies that a mobile service provider may use the common infrastructure of one or various infrastructure providers, whereby it provides services to multiple tenants. This paper aims to study the expected cost savings in terms of capital expenditures (CAPEX) and operational expenditures (OPEX) that can be achieved when using a cloudified 5G multi-tenant network.

A cost model was used. The study period is 2020-2030 and the study area consists of three local districts in central London, UK.

This paper describes that the total cost reduction achieved when using multi-tenancy for a 5G broadband network in comparison with the case where operators make the investment independently ranges from 5.2% to 15.5%.

Further research is needed to assess the cost implications of network sharing for 5G on a regional or nationwide basis.

Very little quantitative research about the cost implications of network sharing under 5G networks has been published so far. This paper sheds light on the economic benefits of multi-tenancy in a 5G broadband network.

This paper aims to examine human resource management (HRM) in the gig economy through a moral economy lens and to uncover how sharing and firm ownership influences the (un)ethical use of HRM practices and worker treatment.

Conceptual and empirical insights from contemporary HRM literature are synthesised through a systematic literature review to elucidate pressing challenges for research and practice.

The analysis reveals that the different ownership structures used by gig firms shape the nature and degree of sharing. The gig economy built on investor ownership leads to greater sharing with investors and tends to be more exploitative of workers, whereas platforms built on collaborative ownership engage in greater peer-to-peer sharing which is more equitable and leads to higher quality work relations and HRM.

The closer an organisation's alignment with the more equitable/relational end of the gig economy spectrum, the better the work relations and HRM.

A new integrated conceptual spectrum of sharing in the gig economy is advanced, which aids in understanding evolving developments in HRM theory and practice.

The purpose of the paper is to assess whether the dysfunctional structure of the Indian mobile communications sector has been improved by a large number of spectrum auctions during the period 2010-2016.

This paper provides a case study of developments in the Indian mobile communications sector primarily during the period 2010-2016. This period has witnessed a large number of spectrum auctions, the results of which are presented and analysed. The particular focus is upon the consequences of these auctions for the structure of the sector which began the period in what can best be described as a dysfunctional state.

The paper concludes that only limited progress has so far been made in improving the structure of the sector. This is due to factors such as political interference, delays in completing merger & acquisition (M&A) activity, badly organised auctions, a scarcity of the right amount of spectrum in the right places and a regional structure that inhibits operators from providing a nationwide presence.

The paper concludes that considerable progress still needs to be made: For example, political interference needs to be harmonised, auction prices need to become market-clearing and M&A activity needs to come to fruition.

The existing analysis of the sector has paid only limited attention to the significance of auctions for the structure of the sector, and this paper provides an analysis of all auctions and M&A activity virtually to the end of 2016, making it unusually up-to-date.

Electronic devices aid communication during new communication phases and the scope of cognitive radio networks has changed communication paradigms through efficient use of spectrums. The communication prototype of cognitive radio networks defines user roles as primary user and secondary user in the context of the spectrum allocation and use. The users who have licensed authority of the spectrum are denoted as primary users, while other eligible users who access the corresponding spectrum are secondary users.

The multiple factors of transmission service quality can have a negative influence due to improper scheduling of spectrum bands between primary users and secondary users. There are considerable contributions in contemporary literature concerning spectrum band scheduling under spectrum sensing. However, the majority of the scheduling models are intended to manage a limited number of transmission service quality factors. Moreover, these service quality factors are functional and derived algorithmically from the current corresponding spectrum. However, there is evidence of credible performance deficiency regarding contemporary spectrum sensing methods

This article intends to portray a fuzzy guided integrated factors-based spectrum band sharing within the spectrum used by secondary users. This study attempts to explain the significance of this proposal compared to other contemporary models.
