Abstract [en]

During recent years, there has been an increasing interest in the potential opportunities that can be attained with promoting Smart Sustainable Cities (SSC); a concept that can be reached based on Information and Communication Technology (ICT). The SSC concept is then considered achievable by horizontal integration of participating industries in its ecosystem in order to empower sustainability. This approach requires cooperation and sharing resources among co-existing multiple industrial verticals as well as collaboration among competitors (Coopetition). As a result, Machine to Machine (M2M) communications, as the most relevant subcategory of ICT in this context, requires proper coopetition patterns in its ecosystem. In this paper we identify the major roles (activities) in the M2M ecosystem in the context of Smart Cities. Next we define the actors who are capable of performing these roles and present a diagram showing plausible business relations among them. Eventually we discuss the complexity of resources in this context and present different forms of sharing resources among participating actors that is based on coopetition.

Abstract [en]

During the recent years several technologies and services based in Internet of Things (IoT) and Machine-to-Machine communications (M2M) have appeared in many different sectors, like healthcare, transport, logistics, media or utilities. When new technologies (like Smart Grid or Smart Energy) appear two types of challenges can be defined: technical and business challenges, therefore innovation has to be applied in both of them. Too often innovation is focus on the technical evolution and underestimated on the business field, however it is a key aspect for new technologies and services to reach commercial success. Traditional business models in the energy sector will suffer big changes in the next years, as the Smart Grid concept is developed.By the advent of new services and applications, horizontal and vertical partnerships with competitors and other actors will take place. In this context collaboration between actors, partnerships and agreements will be of key importance. This paper investigates the different actors involved in a Smart Energy ecosystem, its possible activities and suitable business models for the different Smart Grid building blocks or milestones.

Abstract [en]

During recent years, there has been an increasing interest in the potential opportunities that can be attained with the use of smart devices in order to gather data or automate processes. This type of communications between devices with minimal human intervention is referred to as Machine-to-machine (M2M) communications that can be applied to optimize resources and improve service delivery applications. Smart Grid is one of the M2M communications applications that is attaining more attention during recent years, because of its potential to change the complete energy ecosystem; going from a unidirectional system to a bidirectional one where customers will have an important role in the ecosystem.Depending on the country and its characteristics and situation, Smart Grid development can be very different. This article identifies commonalities and differences in Smart Grid communication development considering the current status in developed and developing countries. The process is done by evaluating the following techno-economic aspects: Technology development, Public initiatives, Regulator policies and Economic situation/Business perspective of the country. The article is concluded by showing that regulator policies regarding the level of liberalization in the energy market are a key element when defining business strategies and different stages of Smart Grid communications development has a critical influence in the definition of business models, as it defines the key activities, partners and value proposition for the business.

Abstract [en]

The Broadcasting sector has been evolved in terms of service production, transmission platform and reception devices in the last few decades. In contrast to cable and satellite platform, which are suitable for fixed reception only, the terrestrial digital platform can support portable, mobile and fixed reception scenarios. In general, there are two options of mobile multimedia service; one is based on a mobile communication network with IP cast known as MBMS (Multimedia Broadcast Multicast Services), while the other is based on broadcast technology. In the context of convergence, the players in the mobile sector argues that unlike traditional mobile  network systems, where the use was restricted to a given application, emerging  mobile networks will be able to carry a variety of services and accordingly separate broadcasting networks will no longer be required. In line with argument, it is not economically viable to roll out dedicated wireless broadband networks by the broadcasters to meet the increasing demand for interactive broadcasting services. That is why the broadcasters may look for innovative mechanism to deliver the broadcast services over mobile broadband network owned by the telecommunication operators.

The focus on this paper is to investigate the incentives and challenges for such trend in developing countries; taking Sudan as case study. The main conclusion in this paper indicate that a potential economic incentive for delivering the broadcasting service over cellular network in Sudan subject to the deployment of high efficient mobile network. Moreover, the mobile operators may consider support such approach considering the increase demand for additional frequency resource.  However, the key challenges remain in how to develop a suitable regulations landscape to assure fair and competitive business practices on hand while guaranteeing the continuation of the public broadcasting service. In this regard, a new regulation framework needs to be developed to separate the three key functions in digital terrestrial broadcasting value chain (namely the content production and distribution). Further on, the necessary interconnection regulations need to put on place in order to pave the way for rollout of common platform that are necessary for interactive and nonlinear services.

Abstract [en]

Nowadays, the increasing mobile data traffic adds extra pressure on the almost congested mobile networks. In order to meet the new demand, mobile operators have to improve their networks but as revenues are not expected to rise, they have to add extra capacity in a cost-efficient way. The solution might come from shifting the mobile data traffic towards indoor alternative networks, an approach known as mobile data offloading.Among indoor solutions two technologies stepped forward, Wi-Fi and smallcells. This paper analyses the two technologies as complementing solutions for macrocell layer in the mobile data offloading context. The main discussed questions are whether the two solutions are interchangeable and what are the risks and pitfalls when choosing one of the two technologies. In order to answer the research questions, based on a proposed real life deployment scenario, a capacity-cost calculation has been driven. Thus, a newly built office building lacking indoor mobile coverage has been considered. Based on the calculated offered capacity, the deployment costs for a comprehensive solution using either of the two technologies have been estimated. The cost of provisioning for different solutions is based on the fact that either of these solutions needs to be built from scratch and no former type of coverage exists.Regarding the interchangeability question, based on the conducted analysis, we claim that the answer is both “Yes” and “No”. “Yes” since the total cost of ownership for each technology is one order of magnitude lower compared to the traditional macrocell deployment. “No”, since deploying a smallcell network is four times more expensive than the Wi-Fi case when the same capacity is required. Thus, we can conclude that Wi-Fi and smallcells are two complementary rather than competing technologies. The goal is to offer a solution where the end-customer cannot tell whether he is connected on Wi-Fi or cellular. Integrating the two technologies into one single offered solution comes as the next normal step, more an evolution rather than a revolution.

Abstract [en]

Cooperation and collaboration with either competitors and/or other actors in the ecosystem seems to become a relevant method for Mobile Network Operators (MNOs) in order to decrease costs and boost revenues at the same time. But, there are always risks and imperfections in front of such models such as losing control over network, empowering existing or potential competitors and unwillingness to contribute evenly in different cases with other actors. In this paper we discuss possible cooperation patterns for indoor smallcell networks, adopted from successful cooperation patterns in macro cellular networks. This is done by analyzing three main areas: Deployment of smallcells, sharing strategies and outsourcing. Based on the works done in this field, an intersection of these three areas is missing that is studying possible cooperation patterns with all possible actors (operators, third parties and Facility owners) of shared smallcell networks.

The aim of this paper is to see how it is possible to enable cases where all involved actors benefit from the cooperation pattern, by looking into existing solutions as well as proposing new patterns that a multitude of actors may be willing to adopt. Since there is no distinct answer for such a question, the proposed Wholesale model or Comprehensive system helps mobile operators to rethink about smallcell specific business models. This investigation enables distinguishing between revenue-efficient and cost-efficient smallcell network deployments for both operators and other investors.

Abstract [en]

The investments in indoor mobile networks are highly related to the spectrum availability and its associated authorization options. The aim of this paper is to discuss the differences in the spectrum demand taking into consideration both wide and local area network deployment requirements and the kind of actor that provides the indoor wireless access. The analysis covers different authorizations options namely licensed, unlicensed, licensed shared access (LSA) and secondary access. A quantitative approach is used to analyze the differences between macrocell and femtocell deployments focusing on deployment cost and spectrum demand. This is complemented by a qualitative study to explore and discuss the strategic business decisions of different actors in view of the available spectrum bands and spectrum authorization options. The main conclusions from this study are; spectrum has more value in macrocell deployment scenarios than in femtocell ones. More spectrum in macrocell deployment scenarios means that operators can deploy less number of new sites and exploit previous infrastructure investments. Femtocell networks are often coverage limited which allows for frequency re-use. As a consequence, the value of spectrum is not the same for mobile network operators (MNOs) and for local network operator (LNOs). MNOs are traditionally confined to macrocell deployment strategies which entail the exclusive usage of licensed bands. While, the use of licensed spectrum by LNOs may incur more cost than the cost of infrastructure deployment. This explains why the use of unlicensed bands is lucrative and viable for LNOs. Furthermore, the LSA scheme may or could soon become an enabler for LNO's business due to the prevailing technical, regulation and policies developments.

Abstract [en]

The regulatory landscape is changing towards more flexible spectrum management schemes. Such schemes are expected to make additional spectrum resources available and lower the spectrum access barriers. Emerging spectrum authorization schemes such as secondary access (TV White Space) and Licensed Shared Access (LSA) are expected to open doors for new actors rather than traditional MNOs to access licensed spectrum resources at reasonable costs. These schemes will allow actors such as Facility Owners (FO), Mobile Virtual Network Operators (MVNO) and Internet Service Providers (ISPs) to invest in indoor mobile network infrastructure. These actors can act as Local Network Operators (LNO) and build their business models around provisioning of mobile services in locations where there seems to be a hole or lack of service coverage in a particular area within the mobile network operators (MNOs) service footprint. This paper highlights the differences between indoor deployment and outdoor deployment in the light of the available spectrum bands to be used and the possible business models for MNOs and LNOs. In short, the possible investment strategies for provisioning indoor mobile services vary between MNOs and LNOs cases due to economic and regulatory aspects surrounding them. The main finding in this study indicates that the willingness of MNOs to invest in dedicated indoor solutions is driven by the balance between the potential revenues and the deployment cost. Moreover MNOs have more spectrum and investment options compared to LNOs who must bond their investment strategies to the available spectrum resources (i.e. the regulations of spectrum access).

Abstract [en]

After year 2000 with the introduction of third generation (3G) mobile networks a new type ofcooperation between competitors emerged, network sharing. Cost reduction is often mentionedas the main driver for network sharing. However, cost aspects are only part of the story “why”operators cooperate. In this paper we discuss multiple aspects of “why” operators cooperate andalso “how” competing mobile operators cooperate.Besides cost the “why” aspect is discussed in terms of market position, market entry andexploitation of the resources and skills of the sharing partner but also drawbacks of sharing. Thepatterns of cooperation are illustrated by analyzing how roles, responsibilities and resources canbe distributed among the mobile operators. The findings are based on case studies where wemake comparison in three different domains. In the time domain we compare network sharing inSweden the years 2000 and 2010. From a cost perspective the drivers to share networks havedecrease since many base station sites can be re-used. Anyway, new network sharing companiesare formed in order to make the network operation more efficient.We also compare cooperation between operators at the Swedish and Indian mobile markets. Inboth countries the competition is very strong. Network sharing is used but in India thecooperation is organized through tower companies, hence the operator cooperation is weak.Finally we look into network sharing principles for indoor network deployment in Sweden. Thecooperation between operators is strong but not as strong as for the network sharing jointventures. The tie between two operators can be said to be weaker since several mobile operators,the facility owner and also enterprises may be included in cooperation. In addition theinvestment risk is lower.
