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.     

An institutional analysis of environmental management in the Korean mobile communications industry

Environmental sustainability in the mobile communications industry can affect corporations not only in the sector but also in other industries by providing solutions to cope with environmental issues. However, despite the significance of environmental sustainability in the industry, there has been a lack of academic attention. This study investigated the environmental issues in the mobile communications industry by adopting an integrated and holistic approach to corporate sustainable management. In addition, the environmental management of mobile network operators was analyzed using the framework of institutional theory. To investigate the environmental management of mobile network operators, we carried out a case study on three Korean mobile network operators including SK Telecom, KT, and LG Uplus. The results demonstrated that economic and environmental issues were mostly found in the mobile communications industry, and the mobile network operators have actively coped with these issues. Their environmental management was relatively active, and regulatory, mimetic and normative mechanisms were working simultaneously. This study provides some meaningful implications for practitioners and policymakers.     

Analysing disruptive potential: the case of wireless local area network and mobile communications network companies

In this article, we analyse the prediction that wireless local area network (W-LAN) technologies will be disruptive for incumbent mobile communications network operators. For this purpose, we develop a methodology of guided interviews to assess technologies for their disruptive characteristics based on theory of disruptive technology developed by Christensen (1997) and recent extensions. The application of our comprehensive step-by-step method improves the precision of the disruptive technology concept and its usability for practitioners to make ex ante distinctions between disruptive technologies and other phenomena caused by emerging technologies. Our method predicts that contrary to common assumptions, W-LAN is not likely to represent a disruptive technology for the established mobile communications network firms in terms of Christensen's concept. This research was conducted in close collaboration with Vodafone Pilotentwicklung, an R&D and technology monitoring unit of the Vodafone Group. Vodafone provided part of the empirical data through expert interviews and market reports.     

Network effects and preference heterogeneity in the case of mobile telecommunications markets

This paper demonstrates how revealed- and stated-preference analyses can be used for modeling network effects in the field of mobile telecommunications. The aim of this study was to verify if network effects may still play a role in the Polish mobile telecommunications market, measure their strength, identify their sources and variability across consumers by accounting for consumers' observable and unobservable preference heterogeneity, evaluate their monetary value to consumers, and finally, to verify if the marginal utility associated with network effects is constant. The analysis of consumers' revealed choices (currently used mobile telephone operator) allowed the identification of major differences between customer bases of incumbent and new entrant operators, and insight into the business strategies adopted in the presence of asymmetric regulation of mobile termination rates. The second part of the study—the analysis of the consumers' stated choices (made in carefully prepared and designed hypothetical choice situations, known as the choice experiments) made it possible to directly model consumers' utility functions and, in this way, investigate the nature of network effects in mobile telecommunications markets. From the results, the presence of strong network effects, which are related to the ratio of consumers' social network group using the same operator, and to the magnitude of on-net price discounts, is confirmed. These network effects can be disaggregated to pecuniary and non-pecuniary effects. Through the utilization of the random parameters multinomial logit model, consumers' observable and unobservable preference heterogeneity can be accounted for, which proved a scientifically revealing and potentially policy-relevant approach. The results might be of a particular interest to other researchers aiming at modeling consumers' preferences as well as to mobile telephone operators and regulatory authorities—it is shown that capacity for vigorous price competition between mobile operators is limited by non-price factors, which affect subscriber's choices, especially in the presence of asymmetric mobile termination rates.     

TP case study: fixed–mobile interconnection in India

The Telecommunications Regulatory Authority of India (TRAI) attempted, in late 1999, to introduce the calling party pays (CPP) regime for mobile cellular services, with a corresponding revenue-sharing arrangement between fixed and mobile operators. According to the revenue-sharing proposal, mobile operators in India were to be compensated for carrying traffic to and from the fixed networks. Under their original license conditions, fixed operators (usually one of the two state-owned incumbents) were not paying mobile operators for terminating calls on their networks. However, mobile operators had to compensate the state-owned incumbent for terminating traffic. This unfavourable environment for mobile operators has meant that mobile services have not been able to reach their full potential in India. There was great disappointment within the mobile industry when the TRAI's CPP order was overturned by the Supreme Court of India in early 2000, due to lack of jurisdiction. Since then, the enabling legislation has been amended. It is hoped that the new provisions of the TRAI Act will empower the regulator to establish a level playing field for mobile network operators. It is only through the creation of a suitable framework for interconnection that the TRAI will be able to ensure the success of telecommunications reform in India.

On regulations for 5G: Micro licensing for locally operated networks

Future 5G networks aim at providing new high-quality wireless services to meet stringent and case-specific needs of various vertical sectors beyond traditional mobile broadband offerings. 5G is expected to disrupt the mobile communication business ecosystem and open the market to drastically new sharing based network operational models. 5G technical features of network slicing and small cell deployments in higher carrier frequencies will lower the investment barrier for new entrants to deploy local radio access networks and offer vertical specific services in specific areas and allow them lease the remaining required infrastructure on demand from mobile network operators (MNO) or infrastructure vendors. To realize the full vision of 5G to benefit the society and promote competition, innovation and emergence of new services when the 5G end-to-end network spans across different stakeholders administrative domains, the existing regulations governing the mobile communication business ecosystem are being refined. This paper provides a tutorial overview on how 5G innovations impact mobile communications and reviews the regulatory elements relevant to 5G development for locally deployed networks. This paper expands the recent micro licensing model for local spectrum authorization in future 5G systems and provides guidelines for the development of the key micro licensing elements. This local micro licensing model can open the mobile market by allowing different stakeholders to deploy local small cell networks with locally issued spectrum licenses ensuring pre-defined quality guarantees for the vertical sectors’ case specific needs.     

Determinants of mobile broadband use in developing economies: Evidence from Sub-Saharan Africa

Broadband is seen as a vector of economic growth and social development. In the developing world, mobile technologies are widely adopted and mobile broadband is progressively rolled-out with high expectations on its impact on the countries’ development. We highlight what the determinants of mobile broadband use are in four Sub-Saharan countries. Using micro-level data coming from household surveys over 5 years, from 2013 to 2017, we show that SIM card ownership and being part of an online social community has a strong positive impact on mobile broadband use. We also highlight a positive correlation between digital inclusion and financial inclusion as mobile money users and bank account users are found to be more inclined to use mobile broadband. However, beyond apparent similarities, mobile broadband is used in different ways according to countries specificities. For instance, among the non-mobile owners in Nigeria, the unemployed are the most likely to use mobile broadband, most probably for job search practices, while it is rather used by students for information gathering in other countries. Finally we show that those excluded from mobile broadband use are the eldest, those with the lowest level of education, and women.     

Customer retention,loyalty, and satisfaction in the German mobile cellular telecommunications market

Customer retention (CR), loyalty (CL), and satisfaction (CS) are important (intermediate) goals for telecommunication network operators on their way to superior economic success in the liberalised German market. Therefore, drawing on a sample of 684 residential customers of digital cellular network operators in Germany this study tests hypotheses suggesting that CR, CL, and CS should be treated as differential constructs which are causally inter-linked. LISREL analyses support a two-staged model in which overall CS has a significant impact on CL which in turn influences a customer's intention to terminate/extend the contractual relationship with his mobile cellular network operator (=CR). Mobile service price and personal service benefit perceptions as well as (lack of) number portability between various cellular operators were identified as supply-related variables with the strongest effects on CR. Mobile network operators’ perceived customer care performance had no significant impact on CR. The findings suggest that an important lever for regulators to promote competition in cellular markets is the enforcement of efficient number portability procedures between mobile network operators.     

Competition in wholesale markets: Do MNOs compete to host MVNOs?

This paper extends previous research examining wholesale market shares of mobile network operators (MNOs). This study demonstrates that wholesale market concentration has decreased over time because of the increase of competition of MNOs for hosting mobile virtual network operators (MVNOs). However, differences in wholesale market shares between MNOs have not disappeared. We propose that those operators that are late entrants in a market and belong to an international group with a proactive attitude towards hosting virtual operators positively influences wholesale market shares of MNOs. The empirical analysis is based on a panel data from 2000 to 2010 corresponding to MNOs and virtual operators in five European countries with high development of the virtual mobile industry. By closely examining KPN we show how being an international mobile group specialising in the wholesale market across Europe has enabled it to exploit complementarities that exist between traditional and virtual businesses.     

Effective competition and ineffective mobile industry regulation in South Africa

The most striking feature of South Africa’s mobile market is the skewed allocation of spectrum and a seemingly endless sequence of failed attempts to hold an auction for it. A shortage of spectrum (or the inefficient assignment of it) is blamed, among other things, for South Africa’s relatively slow LTE 4G speeds. Through historical accident, the country has two mobile data networks in addition to the four licensed mobile operators. The response of operators has been to innovate using roaming and network sharing agreements; as we explore in this paper, these have become the de facto spectrum allocation process.This paper looks at how the de facto industry structure has been moulded by spectrum holdings and sharing arrangements and asks how spectrum management could be improved. We observe that, although the number of mobile operators has effectively been reduced to 3 (a number which would raise concern in some circles), there exist a variety of arrangements between those three and other spectrum and network operators. The smallest of the current three mobile operators is still not able to offer a nationwide mobile service without a roaming agreement but, at the same time, the two larger operators depend critically on spectrum and roaming agreements themselves, mainly with the two physical data network operators that function as wholesale providers.The Independent Communications Authority of South Africa (ICASA) was established as a consequence of a new constitution that was adopted in 1996 and it helped to create new institutional arrangements for the burgeoning mobile industry. The authority has nevertheless continued to be hampered, as we shall demonstrate, by political imperatives. This has been pointed out by other authors over the past twenty years and we add to this body of evidence by considering the spectrum auction planned (again) for 2021.The “2021” auction is in fact an iteration of the auction originally announced in May 2010 and then abandoned (Song, 2011). The same thing happened again in 2016 (Paelo & Robb, 2020). Late in 2020, the regulator again announced an auction, due to take place during 2021 but by the second quarter of the year, two of the four national operators had already obtained a court injunction to stop it. The process is intertwined with a political imperative to establish a public wireless open-access network, which we discuss in detail.We describe how the industry has navigated around policy and regulatory dysfunction and how competitive interaction among the South African operators has managed to prevail. Following Hausman & Taylor’s (2013) lead in their work on the United States, in this paper we provide a commentary on apparently perverse outcomes from significant regulatory, judicial and legislative actions (or, perhaps more accurately, inactions) governing the South African mobile telecommunications industry from the commencement of the current constitutional arrangements in 1996 to the present.     

Evaluation of mobile services and substantial adoption factors with Analytic Hierarchy Process (AHP)

Emergence of new technological innovations in networks, platforms, and applications has enabled service providers to gain back their massive investment in their infrastructures. However, due to lagging adoption, many service innovations have failed to generate profit. The adoption of different mobile service categories depends on several factors. The current explorative study aims to use Analytic Hierarchy Process (AHP) to identify the most relevant mobile services for consumers and the factors driving the adoption. The results of the AHP analyses indicate that functionality of services is of utmost important for the majority of respondents. The results reveal that basic mobile communication services are the most preferred ones, although several services within different categories are available. The results have important implications for mobile network operators, service and application providers on how to develop and implement specific mobile services. The current study also offers new insights for researchers by showing that AHP is applicable to analyze consumers' preferences.     

Network effects in mobile telecommunications markets: A comparative analysis of consumers' preferences in five Latin American countries

It has been shown that the presence of demand-side externalities can induce the market to benefit the largest firms in terms of market share, usually named as network effect by the theoretical literature. On the one hand, macro-level approach in the empirical literature of network effects commonly use the assumption that a network's overall size matters more to consumers' decisions (global network effects). On the other hand, micro-level studies have suggested that social networks are more relevant to consumers' choices than the overall network size (local network effects). Based on microdata from five Latin American countries, we compare the choice of a particular operator over choosing the largest operator by individual consumers. Our research shows that country-level network size is one among a set factors that determine consumers' choices of mobile operators, once individual and operators' country presence heterogeneity are considered. We find that consumers' local network decisions are important for the choice of operator in the majority of cases considered, and that this result is conditional on the chosen operator's market share. Furthermore, network characteristics and consumer preferences, such as coverage, tariffs, and network importance also affect the choice of mobile network for the Latin American context.     

Shrouded transaction costs: must-take cards,discounts and surcharges

The proliferation of new payment methods on the Internet rekindles the old and unsettled debate about merchants’ incentive and ability to differentiate price according to payment choice. This paper develops an imperfect-information framework for the analysis of platform and social regulation of card surcharging and cash discounting. It makes three main contributions. First, it identifies the conditions under which concerns about missed sales induce merchants to perceive that they must take the card. Second, it derives a set of predictions about cash discounts, card surcharges and platform fees that shed light on existing evidence. Finally, it shows that the optimal regulation of surcharging is related to public policy toward merchant fees and substantially differs from current practice.     

Network management in the era of ecosystems: Systematic review and management framework

Business-to-business (B2B) and business network scholars have begun adopting an “ecosystem” approach to describe the increasing interdependence and co-evolution of contemporary business and innovation activities. Although the concept is useful in communicating these issues, the challenge is the lack of overall understanding of the added value of the approach, its particular theoretical logic, and its links to network management. This systematic review analyzes the usage of the ecosystem concept in B2B journals and its implications for network management. Common themes are distilled, the specific features of the ecosystem approach are examined, and four categories of the ecosystem approach are identified: (a) competition and evolution; (b) emergence and disruption; (c) stable business exchange; and (d) value co-creation. We also examine shifts in management opportunities and challenges related to these developments. Finally, we suggest a revised network management framework, where we address the implications of utilizing an ecosystem layer for the analysis, as well as using the ecosystem as a perspective in the management of business and innovation networks. Overall, this study contributes to the literature by providing a coherence-seeking, systematic outlook on the increasingly useful, but still nascent and ambiguously utilized ecosystem approach.     

The response strategies of incumbent mobile network operators on the disruptive potential of public W-LAN in Germany

This paper examines how three incumbent mobile network operators (MNOs) in Germany responded in terms of their strategy to the emergence of the wireless local area network (W-LAN) technology and how they interpreted this potentially disruptive technology in their own strategic context. Additionally, prior empirical results and forecasts on the limited disruptive potential of W-LAN for the German MNOs lacked persuasive firm-level evidence to distinguish the real reason for the presented observations and analysis. So far it was unclear whether the observations were caused by successful response strategies of incumbent MNOs or by the inherent limited disruptive potential of the W-LAN technology. For this purpose case studies of three major MNOs in Germany were performed to assess and compare their respective response strategies. Using the theoretical framework of disruptive technology, the results were evaluated in a cross-case analysis to study how these firms interpreted and reacted to the potential disruptiveness of W-LAN. The results indicate significant differences for the respective MNOs between their perception of W-LAN as a potential disruptive technology, their strategic development processes inside the organisation to understand the potential impact of W-LAN on their respective business model, and to enforce an appropriate response strategy and structural implementation. This incumbent heterogeneity depends primarily on their idiosyncratic strategic and structural context. These findings reveal that the incumbent MNOs in Germany were aware of the disruptive technology concept but did not react in a theory-conform way. However, since W-LAN had a sustaining impact on the MNOs and their response strategies followed sustaining reaction patterns, earlier studies, which show a limited disruptive potential of W-LAN for the German MNOs, are supported.     

Access regulation and infrastructure investment in the mobile telecommunications industry

While mobile virtual network operators (MVNOs) increase competition in the mobile telecommunications industry, granting market access to MVNOs may have unwanted consequences. In particular, infrastructure investment by incumbent mobile network operators (MNOs) may be smaller. This paper examines the effects of MVNO entry and access regulation on the investment behavior of MNOs. It uses firm-level data for 58 MNOs in 21 OECD countries during 2000–2008. The results suggest that mandated provision of access is related to lower investment intensity of MNOs, while voluntary access provision has no effect. Although reduced investment incentives do not necessarily correspond to under-investment, this underscores the need for those countries where MVNOs are provided access to address the issue of investment incentives.     

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.     

AN EMPIRICAL ANALYSIS OF PAYMENT CARD USAGE*

I exploit a unique data set on the payment card industry to study issues associated with network effects and two‐sided markets. I show that consumers concentrate their spending on a single payment network (single‐homing), although many maintain unused cards that allow the ability to use multiple networks (multi‐homing). Further, I establish a regional correlation between consumer usage and merchant acceptance within the four major networks (Visa, Mastercard, American Express and Discover). This correlation is suggestive of the existence of a positive feedback loop between consumer usage and merchant acceptance.
