Risks associated with next generation access networks investment scenarios

The deployment of next generation access networks (NGAs) is investigated from technical, regulatory and investment perspectives. A brief review of the possible network architectures and deployment scenarios of NGAs is provided. Risk calculations of these NGA scenarios are performed based on a fully detailed techno-economic model. Furthermore, the effectiveness of the European Commission's Recommendation on regulated access to NGAs, aiming to tackle the regulatory trade-off between encouraging investments and promoting competition, is discussed

Techno‐economic analysis of 5G immersive media services in cloud‐enabled small cell networks: the neutral host business model

Fifth generation (5G) envisages a “hyperconnected society” with an enormous number of interconnected devices, anywhere and at any time. Edge computing plays a pivotal role in this vision, enabling low latency, large traffic volumes, and improved quality of experience. The advent of 5G and edge computing encourages vertical industries to develop innovative services, which can meet the challenging demands coming from consumers. However, economic feasibility is the ultimate factor that determines the viability of a new service. Hence, effective techniques for the economic assessment of such services are needed. This paper analyzes the provision of immersive media services in crowded events, through a cloud‐enabled small cell network owned by a neutral host, and offered in multitenancy to different mobile network operators. We initially develop a planning model to predict the required compute, storage, and radio resources. Taking into account dynamic factors such as service penetration and price evolution, we then provide a number of economic indices, such as net present value, internal rate of return, and expected payback period to assess the viability of a potential investment in a 5G infrastructure for immersive media services. The presented analysis will guide small cell network operators in the provision of 5G innovative media services

Assessment of socio-techno-economic factors affecting the market adoption and evolution of 5G networks: Evidence from the 5G-PPP CHARISMA project

5G networks are rapidly becoming the means to accommodate the complex demands of vertical sectors. The European project CHARISMA is aiming to develop a hierarchical, distributed-intelligence 5G architecture, offering low latency, security, and open access as features intrinsic to its design. Finding its place in such a complex landscape consisting of heterogeneous technologies and devices, requires the designers of the CHARISMA and other similar 5G architectures, as well as other related market actors to take into account the multiple technical, economic and social aspects that will affect the deployment and the rate of adoption of 5G networks by the general public. In this paper, a roadmapping activity identifying the key technological and socio-economic issues is performed, so as to help ensure a smooth transition from the legacy to future 5G networks. Based on the fuzzy Analytical Hierarchy Process (AHP) method, a survey of pairwise comparisons has been conducted within the CHARISMA project by 5G technology and deployment experts, with several critical aspects identified and prioritized. The conclusions drawn are expected to be a valuable tool for decision and policy makers as well as for stakeholders

Technoeconomic analysis of next generation networks

In this thesis a methodological framework for the technoeconomic analysis of telecommunication networks is presented and used in order to address problems concerning the deployment of next generation access networks (ngn). In the first part ngn are presented with a series of architectures based on copper network, fiber network, free space optical (fso) network and hybrid solutions. In addition fixed mobile convergence (fmc) is addressed. Next issues concerning the technoeconomic evaluation are presented such as indexes for the evaluation of investments, discounted cash flow analysis, real option analysis and risk analysis. In the second part of the thesis the methodology is to address several case studies for ngn deployments using both fixed (fttx) and wireless (fso) architectures. In order to clarify the uncertainty real option analysis is used along with risk and sensitivity analysis. The effects of fmc on an integrated telecom provider are also examined. Finally a system of system approach for the study of cost concerning fttx network deployment is introduced.Η παρουσα διατριβη παρουσιαζει ενα μεθοδολογικο πλαισιο που περιλαμβανει ολα τα απαραιτητα σταδια της τεχνοοικονομικης αναλυσης για την περιπτωση των τηλεπικοινωνιακων επενδυσεων.

Regulatory Considerations in the 5G Era: The 5GCity Neutral Host Case

Part 1: 4th Workshop on “5G – Putting Intelligence to the Network Edge” (5G-PINE 2019)International audienceThe need for densification in 5G networks will necessitate the installation of large amounts of small cells in dense urban environments in order to meet future demands for capacity. The Neutral Host model has been proposed as a potential solution to this problem. This paper discusses the general regulatory considerations of 5G networks and specific considerations that relate to the Neutral Host model as this has been examined as part of the H2020 Project 5GCity

Gastric Cancer-Epidemiologic and Clinical Aspects

Gastric cancer (GC) continues to be an important health threat as the third leading cause of cancer related death in both sexes worldwide. In a recent analysis, the mortality trends for the time period from 1980 till 2011 were significantly downward in all countries, but the declines in the USA, EU and several other major countries were of low magnitude when compared with the past. Furthermore, the relative contribution of cardia cancers compared with noncardia cancers increased among countries with higher GC rates. With respect to preneoplastic changes of the gastric mucosa, a large population-based study suggests that Helicobacter pylori infection and antigastric parietal cell antibodies-mediated autoimmune response might, for the most part, be independent and follow distinct pathways rather than causally related pathways leading to chronic atrophic gastritis. A large prospective, randomized, open-label Korean trial questioned the role of H. pylori eradication for the prevention of metachronous lesions after endoscopic resection of early GC. A review of 1258 Japanese cases undergoing curative endoscopic submucosa dissection for early GC showed that scheduled follow-up endoscopy is mandatory for detecting metachronous lesions at an early stage, where they can be treated by endoscopic resection. Ramucirumab, a vascular endothelial growth factor receptor-2 antagonist, is the first biological treatment that provides survival benefits to patients with advanced GC in progress after first-line chemotherapy. The target agent rilotumumab is currently being evaluated in patients with advanced GC overexpressing the HGF/c-MET signaling pathway. In the near future, ipilimumab and nivolumab, two immunostimulatory monoclonal antibodies with antineoplastic effects, might offer new therapeutic options for patients with advanced GC

Are 5G Networks and the Neutral Host Model the Solution to the Shrinking Telecom Market

Part 2: 5G-PINEInternational audience5G networks will offer advanced functionalities and features such as high throughput, low latency, security and reliability by leveraging technological advances like network virtualization, edge computing and network slicing. The latter will facilitate the entrance of new players in the value chain. Moreover, they will offer a means for network operators to change their business models in order to address revenue losses. The concept of a neutral host supported by the H2020 5GCity project seems to be a strong candidate for future business models helping network operators thrive in the new telecom era
