    [[abstract]]This study investigates the trends followed by MVNOs (Mobile Virtual Network Operators) in the last three years and analyzes the strategies that can contribute to the success of Taiwan's telecommunications industry and marketing. We apply the method and concept of PATTERN (Planning Assistance Through Technical Evaluation of Relevance Number) to establish relevant systems for searching out the key successful factors of strategies to attract MVNOs. We also use the fuzzy Multi-Criteria Decision Making (MCDM) method for analyzing the different preference of a decision group in the criteria weights and for ranking the alternatives in a fuzzy environment in order to provide a strategy scheme. These results provide a reference to assist telecommunications operators, 3G license owners, potential MVNOs, and equipment manufacturers when working out business plans.[[incitationindex]]SCI[[booktype]]紙

    EU-Turkey Accession Negotiations: Impact assessment of Chapter 10 on information society and media

    Get PDF
    In the past few years, Turkey has launched very important and ambitious reforms in the information society and media sector. Even more substantial changes are expected in 2009, after the new e-communications law has been approved at the end of 2008. Apart from the 49 expected pieces of secondary legislation foreseen to implement the new Law No 5809, Turkey has also planned important steps in the domain of spectrum policy, with licenses for WiMAX soon to be awarded. This report analyses the current state of advancement of Turkey\u2019s regulatory reform in this sector, and formulates suggestions for reform on the basis of a complex and articulated impact assessment exercise. Our final conclusion is that Turkey may profit significantly from a set of targeted reforms, aimed at solving existing problems that have been highlighted, i.a., by the European Commission and also by the recent ECTA Scorecard 2008

    The regulation of national roaming

    Get PDF
    National roaming is a measure that can be agreed commercially between operators to extend coverage or can be imposed or facilitated by governments as a means to increase competition amongst networks. It has been used with varying degrees of success in a range of countries, notably in the European Union. It has generally faced resistance from established operators, reluctant to assist prospective competitors and reduce their shares of the market. In some countries implementation has been so poor as to fail in the objectives. The absence of agreed procedures and performance indicators may have contributed to some of those failures. The costs of deploying third generation networks are causing some operators to look at more extensive agreements, sharing radio access networks, rather than national roaming. A further factor has been the lack of prospective entrants in mature markets, making national roaming less important than had been expected. --

    Matching theory as enabler of efficient spectrum management in 5G networks

    This is the peer reviewed version of the following article: Tsirakis, C, Lopez‐Aguilera, E, Agapiou, G, Varoutas, D. Matching theory as enabler of efficient spectrum management in 5G networks. Trans Emerging Tel Tech. 2020; 31:e3769., which has been published in final form at https://doi.org/10.1002/ett.3769. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.This paper analyzes the spectrum trading problem in virtualized fifth generation (5G) networks in order to enhance the network performance with respect to the spectrum utilization. The problem is modeled as a Many-to-Many Matching (M2MM) game with utility-based preferences and determines the matching between mobile network operators and mobile virtual network operators. The two proposed versions of utility functions for each set aim at maximizing the satisfaction of both sets with conflicting interests and improving the overall spectrum efficiency. In the simulation evaluation, the proposed scheme is compared with three different schemes in terms of the system utility, individual and pair matching satisfaction. We also investigate the scalability aspects, the strategy plan impact on the matching performance of our proposed scheme, and, at the same time, we attempt to make appropriate assumptions closer to reality. Our proposed scheme shows much better performance than the other schemes achieving a quite high level of satisfaction for the matching result on both sets.Postprint (author's final draft

    Horizontal cooperation on investment: Evidence from mobile network sharing

    Get PDF
    We present a structural model to investigate the effects of horizontal cooperation on investment in the context of telecommunication networks. More specifically, we estimate the effect of network sharing in the mobile telecommunications industry on prices, network quality and consumer welfare. The presented framework allows estimating the effects of different types of sharing agreements including common ownership of shared assets in a joint venture company or collaboration via geographical separation (geo-split principle). The proposed identification strategy relies on differences in the costs of network deployment of shared versus non-shared network infrastructure, with different costs affecting operators’ optimal choice of price and network quality. We apply the structural model to estimate the effects of a network sharing agreement in the Czech Republic, using a combination of unique datasets on prices, network quality measured as average download speed and operator’s costs of network deployment. The results of our model indicate that horizontal cooperation on investments may be beneficial for consumers. Specifically, the network sharing agreement under study generated cost savings for the sharing parties, which were passed-on to consumers in the form of lower prices and higher average download speed. Our findings are of relevance to the assessment of network sharing agreements, which, considering the substantial investment cost associated with the 5G technology, are likely to play an even greater role in the telecommunications industry in the future. The findings are also of relevance to the general literature on horizontal cooperation on investments
