    The National Broadband Network (NBN) will deliver a comprehensive upgrade to Australia’s national broadband infrastructure. This will be of profound importance to Australia’s long-term productivity agenda. This paper, commissioned by Vodafone Australia, assesses new opportunities for the NBN. In particular, we examine how the growth of mobile services has transformed the telecommunications industry and how NBN has the potential to dramatically improve mobile telecommunications. It makes the case that the NBN, far from becoming redundant due to the explosion in mobile internet access, is in fact crucial to delivering better mobile services to both regional and urban areas without any significant increases in cost. It argues that the recent development of small mobile base stations (able to be placed on lampposts for example), connected to the NBN, can significantly increase and improve mobile coverage in both urban and regional Australia. This has the potential to radically reshape Australia’s economic and social future

    Indian Internet and broadband market has experienced very slow growth and limited penetration till now. The introduction of Broadband Wireless Access (BWA) is expected to aid in increasing the penetration of internet and broadband in India. The report sheds light on the guidelines and procedure used in 4G/BWA spectrum auction and presents comparative analysis of the competing technologies, providing the information about suitability of each technology available. Recently held 4G/ BWA spectrum auction saw enthusiastic participation by the industry and even saw some new entrants in Indian broadband market. Government benefited by Rs, 385bn that it earned as revenue from the auction of the spectrum and projected it as successful auction. However, the question remains if the auctions were efficient and whether they led to creation of value or will it prove to be burden to the telecom operators and will depress their balance sheet for years to come. The report uses both traditional valuation methods such as Discounted Cash Flow as well as Real Option approach to answer such questions. Using DCF analysis, the broadband subscribers have been forecasted to grow from present 13.77mn to 544mn by the end of 2025. The wireless subscribers are forecasted to be 70% of the total broadband subscribers after 5 years of roll out as it will be difficult to replace all wireline subscribers with wireless subscribers in India due to the high cost of wireless broadband and new technology. WiMAX is expected to increase its presence with time and reach 90mn subscribers from meager 0.35mn subscribers by 2025. Using industry wide cost of capital as 12.05%, the Net Present Value has been found Rs 221bn aggregate with an IRR of 17.1%. Using Real option approach, the value of license has been calculated as Rs 437bn which is 13.5% more than the spectrum fees paid by the operators. This mismatch, between the auction value and the correct value that should have been discovered by supply-demand dynamics, can be due to limited participants in BWA spectrum auctions and companies such as TATA and Reliance opting out of the auction process midway as well as uncertainty about acceptance of new technology with Indian subscribers.WiMAX, broadband, 3G spectrum, 4G,broadband wireless access, valuation, licensing, real option

    Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

    Get PDF
    In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

    Survey of End-to-End Mobile Network Measurement Testbeds, Tools, and Services

    Full text link
    Mobile (cellular) networks enable innovation, but can also stifle it and lead to user frustration when network performance falls below expectations. As mobile networks become the predominant method of Internet access, developer, research, network operator, and regulatory communities have taken an increased interest in measuring end-to-end mobile network performance to, among other goals, minimize negative impact on application responsiveness. In this survey we examine current approaches to end-to-end mobile network performance measurement, diagnosis, and application prototyping. We compare available tools and their shortcomings with respect to the needs of researchers, developers, regulators, and the public. We intend for this survey to provide a comprehensive view of currently active efforts and some auspicious directions for future work in mobile network measurement and mobile application performance evaluation.Comment: Submitted to IEEE Communications Surveys and Tutorials. arXiv does not format the URL references correctly.

    Life is short. The impact of power states on base station lifetime

    Get PDF
    We study the impact of power state transitions on the lifetime of base stations (BSs) in mobile networks. In particular, we propose a model to estimate the lifetime decrease/increase as a consequence of the application of power state changes. The model takes into account both hardware (HW) parameters, which depend on the materials used to build the device, and power state parameters, that instead depend on how and when power state transitions take place. More in depth, we consider the impact of different power states when a BS is active, and one sleep mode state when a BS is powered off. When a BS reduces the power consumption, its lifetime tends to increase. However, when a BS changes the power state, its lifetime tends to be decreased. Thus, there is a tradeoff between these two effects. Our results, obtained over universal mobile telecommunication system (UMTS) and long term evolution (LTE) case studies, indicate the need of a careful management of the power state transitions in order to not deteriorate the BS lifetime, and consequently to not increase the associated reparation/replacement costs

    Exploring value co-creation within buyer-seller relationship in mobile applications services : a model development

    Mobile phones have become an indispensable part of consumers’ life where they access core and supporting services via mobile applications services (m-applications). The focus of the present study is to explore dyadic buyer-seller roles in m-applications services’ value creation taking mobile banking applications services (MB-applications) as a case study. While prior research on value co-creation in service dominant logic (S-d logic) serves as a foundation for this study, it does not provide adequate guidance on how buyer and seller co-create value in m-applications services.To address this shortcoming, semi-structured interviews were carried out with 12 banks’ officials in banks’ headquarters of Saudi Arabia. Also, six focus groups were conducted; three with MB-application services users and three with non-users which were held in Riyadh College of Technology (RCT). In addition, a content analysis of MB-applications services was conducted to support suppliers’ perspectives regarding value propositions (service offering). A conceptual framework is developed for managing co-creation to illustrate practical application of the framework.The findings pointed to six factors that shape shape service suppliers’ ability to offer and deliver value via MB-applications, namely; brand image building, bank’s business vision, customer culture-orientation, bank’s internal environment, information technology system and positioning strategy. These factors combine to establish a value proposition for banks’ customers in the MB-applications services domain.Customer’s value creation as value in-use during usage emerged in different usage situations. A value framework incorporating value consumptions (Sheth et al., 1991a) is proposed. It identifies the main value-adding elements in m-applications and the primary drivers for adopting m-applications. Findings revealed that bank managers attempted to support customers’ value creation, which was reflected in MB-application content. However, support was constrained by some insufficient assumptions about customers and the m-commerce architecture. Factors that impede MB-applications use include consumers’ banking habits, perceived risk (security and privacy); usability hindrance, marketing and promotion, technical problems, and socio-cultural barriers. Implications are drawn for service delivery value perception and mobile marketing theory, and recommendations are made to service suppliers and commercial banks to achieve sustained returns of investment from MB-applications services
