Platform configurations for local and private 5G networks in complex industrial multi-stakeholder ecosystems

Data and connectivity platforms play a crucial role in the digitalization of different sectors of our society. In complex industrial multi-stakeholder ecosystem contexts connectivity and data platforms are increasingly becoming converged, and private, vertical-specific local 5G networks are emerging. For this context, we depict and analyze alternative configurations for converging connectivity and data platforms and propose appropriate management actions for combining these platforms and achieving legitimacy. We examine a complex industrial multi-stakeholder ecosystem of a port and observe that in the considered case study, the convergence of connectivity and data platforms enhances digitalization and helps to create shared local information between stakeholders. The research identifies a set of regulatory challenges for local 5G networks in complex industrial multi-stakeholder ecosystems where the telecommunication and information technology-related regulations meet with vertical-specific regulations, leading to a complex environment in which to operate. As highly country-specific, these regulations can open new business opportunities or significantly slow down or even prevent a market opening to local private 5G networks for vertical-specific use.     

5G networks: Will technology and policy collide?

Despite being still under development, it is envisaged that 5G networks will provide a ‘fibre-like’ experience to mobile users. As such, they are expected to accommodate services with very different requirements in terms of latency, bandwidth and reliability, among others, for the vertical sectors. However, the European Union has just approved the Telecommunications Single Market Regulation, which enshrines the network neutrality principle and guarantees that ‘all traffic through the Internet is treated equally’. This article explores the potential conflict between net neutrality regulation and future 5G services, particularly regarding network virtualisation. We present a discussion on the challenges of building net neutrality upon judgements on whether traffic optimisation is objectively necessary. This proves complex in a technological environment that envisions network ‘slices’ created and priced on-demand according to the Quality of Service (QoS) required by specific applications at any given time. In addition, we argue that the ‘anything-as-a-service’ paradigm might turn into an important source of innovation for the future Internet infrastructure layer, and thus for the ecosystem as a whole.     

A business case for 5G mobile broadband in a dense urban area

5G networks are envisioned to provide consumers and industry with improved transmission performance and advanced communication possibilities. To deliver on this promise of ushering in faster downloads and lower latency, mobile network operators are called upon for substantial investment in network infrastructure. Investors and operators need a clear 5G business case before making such investment. So far, very little research has been published on the topic of the 5G business case. This article studies the impact of different elements driving the business case of a 5G network. The study was performed within 3 boroughs of central London, UK, for the period 2020–2030. 5G-related costs and revenues were calculated to derive the business case. The results show that the business case for a 5G network providing mobile broadband services alone is positive over the time period 2020–2030 but has some risk in the later years of this time period. The business case is also particularly sensitive to assumptions on the revenue uplift and the rate of traffic growth which are inherently challenging to forecast. The sensitivity analysis shows that the return on investment becomes negative if both traffic and costs are significantly higher and revenues increase more slowly than our baseline forecasts. Network sharing helps to substantially improve the business case. Further research is needed to understand the business case on a regional or nationwide basis, and for a network that provides additional services beyond broadband.     

Xiaolingtong versus 3G in China: Which will be the winner?

Xiaolingtong (XLT), a new type of mobile phone system based on PHS technology for wireless access of fixed-line telephone networks, has grown very rapidly in China. However, there are many doubts about the future of XLT once 3G (the third generation of mobile communication) is finally employed. This paper proposes a theoretical framework to assess and compare XLT and 3G from four perspectives: technology, market demand, business models and government policy. It concludes that XLT and 3G will coexist with existing 2G/2.5G mobile communication networks for a considerable period of time. With service collaboration and integration, the coexistence of both of these technologies can enhance China's mobile communication infrastructure and support the growth of mobile commerce.     

Analysing the C-Band spectrum auctions for 5G in Europe: Achieving efficiency and fair decisions in radio spectrum management

This paper offers a detailed analysis of selected regulatory parameters used as instruments to promote efficiency with fairness for all stakeholders (in the legal sense of equity) in 5G spectrum auctions. Data were collected from sixteen auctions for the C-band that took place in the Member States of the European Union (EU) and in the United Kingdom (UK) between 2017 and 2020 for the introduction of the fifth generation (5G) of mobile communication technology. The selected instruments of intervention are: spectrum packaging, spectrum caps, set-asides, geographical scope of the license, license duration, various forms of license obligations, reserve prices and auction format.Significant differences were observed in national approaches to spectrum packaging, license obligations and reserve prices for efficiency purposes. Our analysis also shows that European national regulators are paying increasing attention to concerns over fairness of decisions on spectrum, or equity, especially by creating opportunities for local private networks to access the spectrum and by imposing requirements on network operators to guarantee more uniform population coverage of newly created 5G networks.     

Internet of things and the economics of 5G-based local industrial networks

Fifth generation (5G) networks raise governance and management challenges that did not exist in 3G and 4G wireless technologies. Advanced wireless functionality enables new applications and services based on smart, physical, network infrastructures, many of them expected to be localized. As a general-purpose technology, 5G can be configured in numerous ways to support innovative applications across many sectors. Smart network applications and services must integrate physical and virtual components in innovative ways. In addition, general capabilities of 5G must be combined with complementary technologies, such as big data analytics and edge cloud services, to create services for specific use cases. Varying throughput and latency requirements of distinct use cases require differentiated technical solutions. Appropriate frequencies must be aligned efficiently with other features within the footprint of particular, local industrial networks. National policy makers, suppliers, and users are responding differently to these governance and management challenges. These approaches balance differently the trade-offs between experimentation, differentiation, and harmonization. Comparative analysis can inform gradual improvements of the governance of 5G-based, local industrial networks.     

The role of mobile network operators in next-generation public safety services

Field of researchThis research is in the field of public safety communications in mobile broadband 4G/5G networks. The focus is on mobile network operators and their business opportunities in the public safety market.PurposeThe purpose of this research is to provide a review of ongoing public safety mobile broadband projects in which mobile operators play a key role. In addition, a business model analysis is presented to determine the role of mobile operators in these projects. A comparison of the two key business models is also included to reveal their general characteristics.Methods and dataThe research used a qualitative method, an inductive case study. This method was used to draw general conclusions from a small number of case studies based on ongoing public safety mobile broadband projects. The Casadesus-Masanell and Ricart framework and the business model canvas were used to analyse and compare the two key business models discussed. Data were collected from a variety of sources, including company reports, press releases, international events and conferences, and selected interviews with managers in charge.FindingsThe results show that mobile operators have new business opportunities in the public safety market. Their existing mobile networks can be used for public safety services with certain enhancements. Within existing projects, mobile operators have different business models. The two analysed models were found to require different resources and offer different business opportunities for mobile operators. Procurement authorities responsible for selecting business models are encouraged to pay attention to the choice of model based on, for example, strategic objectives.ValueVery little research has been done on the business opportunities of mobile operators in the public safety market. In this area, this study lays the groundwork for new research. Procurement authorities can use the results when deciding on the business model. Mobile operators can benefit from these results by better understanding their own roles in public safety projects and when assessing the business opportunities of a particular project.     

Cognitive radio systems specific for IMT systems: Operator’s view and perspectives

Cognitive radio (CR) is still an emerging and disruptive communication technology which is expected to improve the overall efficiency of the spectrum use. It is envisaged that cognitive radio systems (CRS) could impact many aspects of communications and in particular could facilitate accommodation of the increasing amount of services and applications in wireless networks. Intensive research on CR aims at maximising the utilisation of the limited radio spectrum resource. There have been many advances in CR regarding the technology development aspects; however supplementary research on regulation, policy and market structure reforms in relation with application specific deployment is still required before any CR-based spectrum access could be implemented for specific broadband mobile applications. Indeed, mobile community is still at an early stage of understanding and development of CR capabilities and it is premature to envisage wide deployment of CRS without careful consideration of regulatory and business issues. Therefore, this paper gives a classification of CR-based network and application scenarios, and investigates the feasibility of them from a regulatory perspective at a global level (ITU-R). Main part of this paper presents the wireless network operator’s approach to CRS specific for International Mobile Telecommunications (IMT) systems and proposes the radio environment map (REM) concept as a cognitive tool that increases environmental awareness in wireless network operator’s networks. Studies, which the authors performed internally and within the framework of a collaborative European project as well as within ITU-R yield the conclusion that, at shorter term, only intra-operator based CRS maximises the possibility for CR capabilities to be implemented.     

How disruptive is 5G?

The hypothesis is put forward that, after three decades of stability, there is now the prospect of significant change in the vertical and horizontal structure of the mobile market place. On the supply side, significant factors are, first, the availability of a new and very powerful form of mobile connectivity in the shape of 5G, and second, software defined networking, which allows a single network to provide a variety of heterogeneous services or ‘slices’. On the demand side, the digital transformation of the whole economy (and not just the communications sector) creates the need for diverse communications functions operating in a universe with a much wider set of digitally transformed services.Mobile operators will find themselves contesting customer relationship with firms or other organisations providing these services in an integrated fashion, and thus risk replacing their direct link with end users with becoming the wholesale supplier of an expanded but ‘commoditised’ communications product. We may also observe fewer radio access networks; more competitive backhaul; and the (partial) vertical disintegration of mobile network operators. The regulatory changes implied may include heavier regulation of fewer RANs, and the need for market analyses to confront situations in which network operators sell more and more of their services to a variety of heterogeneous content and application providers – some of them exercising substantial levels of market power.     

Ultra-fast broadband investment and adoption: A survey

In recent years, and in line with EC plans, telecom operators have been facing the need to deploy high-speed, fiber-based infrastructure. What is the socio-economic impact of these new investments on growth and local development? What are their effects on the labor market outcomes, in terms of firm productivity and entrepreneurship? What is the role of regulation and competition in spurring the deployment and the adoption of ultra-fast broadband networks? In this survey, we review the existing literature on ultra-fast, fiber-based broadband network, devoting special attention to the results and to the methodology used in the most recent studies.     

Korea's leadership in 5G and beyond: Footprints and futures

The Korean government has played a crucial role in the development of advanced mobile networks, including 5G. Korea became the first country in the world to not only launch a nationwide 5G network but also to commercialize 5G services. In addition to looking at the steps toward 5G-related developments in Korea, this study used Latent Dirichlet Allocation (LDA) topic modeling analysis to examine how 5G-related discourse was formed in the media after its commercialization. As a result of analyzing news articles in the Korean press with 5G as the main keyword, a total of five topics were derived. Intriguingly, most topics contained several new articles related to government policies. Considering the characteristics of the mobile network industry—e.g. as an industry that receives licenses from the government—this result suggests that 5G-related issues are closely related to government policies. Our topic modeling results confirm that the interventionist promotion policy of the Korean government which acted as a catalyst for technology and business innovation played an important role in Korea's 5G leadership.     

Business ecosystem strategies of mobile network operators in the 3G era: The case of China Mobile

In order to define the mobile network operators' strategies of building value network in the 3G era, this paper applies the ecosystem principles to the mobile industry through a China Mobile case study. Based on an analytical framework of such principles, this paper reviews China Mobile's ecosystem, and identifies its success factors and problems. The results indicate that a complete ecosystem, where mobile network operators collaborate closely with value-added service providers, content/application providers, equipment and device manufacturers, and other involved organizations, can promote the development of mobile data services substantially. Therefore, mobile network operators should play a central role in the ecosystem by managing the entire value-chain and setting up proper value-sharing mechanisms. However, while doing so, problems may arise because of regulatory issues and information asymmetry. High-value common assets, a centralized management system, partner selection schemes and continuous innovations are important success factors.     

A business case for 5G services in an industrial sea port area

5G is a technology that was designed to provide citizens with access to faster and innovative wireless services. While different technical aspects related to 5G have been extensively examined by researchers worldwide, a lack in the existing literature is the economics of 5G in terms of business cases of specific 5G use cases. In this article we analyse the business case for three 5G use cases in an industrial sea port area, the Hamburg port in Germany, over the period 2020–2030. The first use case is enhanced mobile broadband and the results show a payback period lower than one year for all the scenarios analysed. The second use case is automation of container handling in the port's container terminal. It was found that the payback period is also lower than one year with a positive business case net present value in all scenarios studied. The business case of the third case, augmented reality for construction projects in the port's area, is challenging as the payback period was 5 years for the baseline case. Moreover, when performing the sensitivity analysis, it was found that in several scenarios there was a negative return on investment, and it was not possible to recover the investment over the time period studied. It can be concluded that mobile network operators will need to be careful as not all new 5G service offerings may have a positive business case. Future research work should focus on studying other 5G use cases in the port area, and on examining other industrial areas beyond ports such as airports, science parks and manufacturing facilities.     

The impact of regulating mobile termination rates and MNO-MVNO relationships on retail prices

A mobile virtual network operator (MVNO) provides mobile telecommunication services by eluding the constraints of the radio communication infrastructure and establishing an agreement with a hosting network operator (HNO) for the use of its spectrum. Thus, MVNOs offer a wide range of mobile services and directly compete with every mobile network operator (MNO). This paper studies the economic justifications for potential regulatory intervention that defines the level of mobile termination rates (MTRs) and negotiations and agreements among MVNOs and HNOs. The results show that symmetric MTR reduction leads to competition growth among operators, forcing every operator to reduce retail prices and, consequently, to enhancing consumer welfare. The paper also finds that a collaborative strategy adopted by an HNO and an MVNO is advantageous for both and induces a reduction in retail prices, thus weakening other MNOs.     

Forming a 5G strategy for developing countries: A note for policy makers

This paper aims to provide policy makers in low income and middle income countries with a pragmatic review of the critical issues in formulating effective strategies and planning to embrace the next generation of mobile cellular technology. In a context of industry lobbying of governments to promote 5G, the paper attempts to bring clarity to just what are the critical issues, specifically for an industrial policy to deal with this novel but complex technology. Planning for 5G is a series of complicated choices as there are issues at the levels of creating ecosystems to support it, unproven business models, with claims for applications which may not be financially viable, yet, plus confusion over choices of radio spectrum, and selection of equipment suppliers, even potential issues over public health, as well as the real level of industrial and consumer demand beyond the hype. The emphasis here is on the importance of making balanced strategic choices, by identifying the basic issues, in a ‘realpolitik’ fashion - including why embrace 5G at all. The paper develops its insights from lessons learnt in the introduction of the previous mobile generation, LTE, also from policy studies on small cells and on designing auctions for 5G networks, as well as various 5G-focused publications from governments, regulatory authorities, mobile industry associations and global suppliers over the past six years (2015–2020). It examines whether to regulate 5G deployment with a heavy or light-touch regime, also whether to focus on more than the traditional indicators, such as penetration and coverage, or on “transformational outcomes” (as the promotional literature terms them) for the private and public sectors.     

Diffusion of mobile handset features: Analysis of turning points and stages

Mobile handsets have evolved into advanced devices with a rich variety of hardware and software features enabling the use of variety of applications, networks, and services. Consequently, mobile handset features constitute an important part of the global communications infrastructure. Modelling the diffusion of mobile handsets as a product category is becoming less relevant as the market is approaching saturation especially in the developed countries. Simultaneously, the diffusion of mobile handset features is increasingly important and of interest to many stakeholders. This article analyzes and compares the diffusion patterns of mobile handset features, using a longitudinal annual dataset of the penetrations of 15 different features in Finland between 2005 and 2010. Two major turning points – the takeoff and the inflection point – as well as the durations of the diffusion stages between these points are determined. The results show large variations between different features, highlighting the significance of the introduction stage in the diffusion process. The results are useful for regulators and companies in understanding the pace of change taking place in the communications infrastructure.     

The competition among mobile network operators in the telecommunication supply chain

In the mobile telecommunication sector, the high competitiveness has increased the complexity of strategic interactions among operators. As the vertical integration has become anything but a choice and not a compelling technical solution, the contest takes place at different levels of the components of the operator value chain: the network infrastructure, the service development and supply, and the relationship with consumers.Mobile virtual network operators act as retailers and concentrate on the last segment of the value chain by establishing commercial agreements with hosting network operators, which act as manufacturers, to get access to radio communications infrastructure. Productive processes of mobile services offered by operators are different and this difference is imperceptible to customers. Processes difference mainly consists in the infrastructural diversity of the operators and implies different consequences on each network service element.A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.     

Unbundling and infrastructure competition for broadband adoption: Implications for NGA regulation

The common idea of open access policy is that it refers to the sharing of particular elements, such as wholesale access networks, backhaul, under-sea cable and internet exchange points in fixed and mobile networks. In broadband networks, the use of open access policy usually refers to the infrastructure parts, which are considered a bottleneck. Many regulators have generally focused open access policy on fixed broadband networks, especially digital subscriber line (DSL) technology, in the last decade. Local loop unbundling (LLU) regulation is one of the main strategies for the regulator to open access to an incumbent’s bottleneck network in order to soften its monopoly power and encourage competition in the DSL broadband market. The OECD countries have different strategies regarding unbundling local loop and infrastructure competition, as the characteristics and infrastructure networks of countries vary. There are currently more choices of next generation network (NGN) technologies to develop. While local loop unbundling may not be applied fully to NGN development (the cost is not sunk, more technologies are available to implement, incentive of investment by operator), it can indicate benefits and drawbacks of open access policy in the past decade that can be adapted to NGN.The empirical results of this study show that during 2002–2008, LLU regulation was one of the strategies used to increase broadband adoption in countries that had difficulty encouraging infrastructure competition. Unbundling regulation can therefore be implemented carefully and differently in each country that has inefficiency that is harmful to consumers in its market from a monopoly incumbent. Infrastructure competition, on the other hand, is introduced as another strategy to increase broadband adoption. The empirical results of this study indicate that infrastructure competition can be used as a strategy when there are already enough infrastructures in the area or country. These results support the idea of using open access and infrastructure competition policy depending on the existing competition of broadband infrastructure in each country.     

The 3G transition: Changes in the US wireless industry

The transition of the wireless industry from second generation (2G) to third generation (3G) is more than a simple technology upgrade. The industry's service profile will move far beyond telephony and services will converge with the computing and content sectors. This will bring many more players into this already huge industry. Thus the transition to 3G needs to be regarded as a major economic transformation as it requires a major reconfiguration of the existing value networks. Standards have traditionally been essential in the success of wireless services and will play an increasingly critical role in the future.Due to the on-going transition, wireless standardization has changed considerably—reflecting changes in the configuration of the value network. While the number of major air-interface standards has been reduced to just two, the overall number of standards bodies has increased by almost an order of magnitude while the number and scope of interfaces being standardized has grown at a breathtaking pace. This growth reflects the need to support the industry's new coordination requirements at critical interfaces in the value network. At the same time, the importance of the traditional standards development organizations (SDOs) has diminished as more nimble industry consortia have taken over the main responsibilities for standardization. The major standardization battlegrounds have shifted up the protocol stack to the service enabler level. In addition, the manufacture of handsets and other mobile communication devices is transitioning to a more horizontal industry structure. These changes, along with changes in the way value is extracted from new services and their influence on the reconfiguration of the industry are discussed.
