Network sharing and co-investments in NGN as a way to fulfill the goal with the digital agenda

The European Commission and most European countries have set ambitious broadband targets aiming to provide up to 100 Mbits to the end-customers. On back of a declining fixed market, negative growth for operators and a slow take up of fiber while maintaining high capex levels operators will ultimately be forced to take innovative approaches towards broadband investments. This paper relates co-investments in NGA to the regulatory framework in the form of SMP regulation and competition law making the conclusion that the current regulatory framework is sufficient to avoid a distorted competition on the market. A number of examples of ongoing co-investment projects are presented underscoring a growing interest for co-investments and indicating that co-investments, at this point, are not hampering competition. The mobile industry has gradually moved towards network sharing indicating a tendency towards vertical disintegration, although so far only a tendency. The ongoing structural separation of Telecom New Zealand with the establishment of a separate network and wholesale company is an indication of this development. The paper concludes by stating that regulators have appropriate tools to handle potential competition issues regarding coinvestments, that co-investments could be a vehicle for reaching the broadband targets, that there are efficiency gains for operators to make by lower Opex and capex, and ultimately giving network companies the means to utilize their balance sheet in order to increase the return.NGA,co-investment,SMP regulation,horizontal and vertical agreements,capex,network sharing,financial gearing

Will SDN be part of 5G?

For many, this is no longer a valid question and the case is considered settled with SDN/NFV (Software Defined Networking/Network Function Virtualization) providing the inevitable innovation enablers solving many outstanding management issues regarding 5G. However, given the monumental task of softwarization of radio access network (RAN) while 5G is just around the corner and some companies have started unveiling their 5G equipment already, the concern is very realistic that we may only see some point solutions involving SDN technology instead of a fully SDN-enabled RAN. This survey paper identifies all important obstacles in the way and looks at the state of the art of the relevant solutions. This survey is different from the previous surveys on SDN-based RAN as it focuses on the salient problems and discusses solutions proposed within and outside SDN literature. Our main focus is on fronthaul, backward compatibility, supposedly disruptive nature of SDN deployment, business cases and monetization of SDN related upgrades, latency of general purpose processors (GPP), and additional security vulnerabilities, softwarization brings along to the RAN. We have also provided a summary of the architectural developments in SDN-based RAN landscape as not all work can be covered under the focused issues. This paper provides a comprehensive survey on the state of the art of SDN-based RAN and clearly points out the gaps in the technology.Comment: 33 pages, 10 figure

Mobile Communications Industry Scenarios and Strategic Implications for Network Equipment Vendors

Mobile infrastructure markets have changed dramatically during the past years. The industry is experiencing a shift from traditional large-scale, hardware-driven system roll-outs to software and services -driven business models. Also, the telecommunications and internet worlds are colliding in both mobile infrastructure and services domains requiring established network equipment vendors and mobile operators to transform and adapt to the new business environment. This paper utilizes Schoemaker's scenario planning process to reveal critical uncertain elements shaping the future of the industry. Four possible scenarios representing different value systems between industry's key stakeholders are created. After this, five strategic options with differing risk and cost factors for established network equipment vendors are discussed in order to aid firm's strategic planning process. --

SDN/NFV-enabled satellite communications networks: opportunities, scenarios and challenges

In the context of next generation 5G networks, the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and more flexible integration of satellite and terrestrial segments, providing satellite network further service innovation and business agility by advanced network resources management techniques. Through the analysis of scenarios and use cases, this paper provides a description of the benefits that SDN/NFV technologies can bring into satellite communications towards 5G. Three scenarios are presented and analysed to delineate different potential improvement areas pursued through the introduction of SDN/NFV technologies in the satellite ground segment domain. Within each scenario, a number of use cases are developed to gain further insight into specific capabilities and to identify the technical challenges stemming from them.Peer ReviewedPostprint (author's final draft
