A secondary market for spectrum may be implemented through the use of reservation mechanisms, by which prospective consumers of spectrum portions may first book them and decide later whether to actually buy the usage rights. A possible strategy for the owners of usage rights is to practise overbooking, i.e., to allow for more reservations than what they could sell (and then pay a penalty if they cannot satisfy the requests). A relevant problem for the owners of usage rights is to set the price for reservations. An algorithm is proposed here to price reservations in the presence of overbooking. The algorithm is based on the iterative use of the Cox-Ross-Rubinstein approach to price financial call options. The algorithm is then applied to a number of cases and the dependence of the price on the overbooking probability and the penalty is analysed.","PeriodicalId":269841,"journal":{"name":"2010 9th Conference of Telecommunication, Media and Internet","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115486404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It consists of an investment for the years to come that speeds development in more than one technological area and promotes overall growth. Nevertheless in a context of continuous effort for more cost effective and energy saving solutions, the need to invest in a structure that is free from excessive expenditure and at the same time is future-proof has become imperative. Deriving of this need, new technological solutions have begun to emerge and the tool for their financial evaluation could be proven of important value for optical network operators. This paper presents a techno-economic comparison of two different passive FTTH network technologies/architectures. The cases considered in this study are namely: i) metro ring in combination with gigabit passive optical networks (GPON) technology on the access part and ii) a new converged access-metro wavelength division multiplexing / time division multiplexing (WDM/TDM) passive optical network (PON) called: scalable advanced ring-based passive dense access network architecture (SARDANA). This work includes a quantitative modeling of the outside plant cost as well as of the active equipment cost of the two architectures. It is shown that the green solution of the PONs in combination with the expected energy savings guarantees a cost effective solution. Furthermore it is shown that the more elaborate design of the WDM/TDM PON provides a cost reduction of about 15% for densely populated areas and even greater for scarcely ones along with an ensured flexibility.","PeriodicalId":269841,"journal":{"name":"2010 9th Conference of Telecommunication, Media and Internet","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129575360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, ICT is responsible for 4 % of the annual energy consumption and this number is expected to grow drastically in the coming years. The power consumption of these wireless access networks will thus become an important issue in the coming years. In this paper, the power consumption of wireless base stations for mobile WiMAX, HSPA and LTE is modelled and compared for a future scenario. For our research, we assume a suburban area and a physical bit rate of 10 Mbps. We compare the wireless technologies for a SISO and three MIMO systems. For each case, we give a ranking of the wireless technologies as a function of their power consumption, range and energy eff ciency. Based on these results, we cover a specif ed area with each technology and determine which technology is the best solution for the specif ed area. We also compare the power consumption of the wireless access networks with the power consumption of the wired access networks.","PeriodicalId":269841,"journal":{"name":"2010 9th Conference of Telecommunication, Media and Internet","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123819987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A well-founded choice of the technology to be used for the outdoor network connection is investigated in this paper. Several wireless technologies - including HSPA, E-UTRA and WiMAX - are compared by calculating their wireless ranges for reception outside and inside trains, based on the location of the transceiver. These wireless ranges determine the number of base stations needed to cover a pre-defined area along a railway track. Results show that generally 3G (UMTS-HSPA) and 4G (E-UTRA/LTE) technologies offer the best coverage over a range of data rates, from 2 Mbps to 8 Mbps. These data rates relate to a wide variety of services, from network control data, surveillance, crew services to passenger Internet traffic.","PeriodicalId":269841,"journal":{"name":"2010 9th Conference of Telecommunication, Media and Internet","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115985359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This increasing necessity is due to growth of both spectrum demand and offer. On the demand side, soaring mobile broadband has made mobile operators demand additional spectrum to improve their network efficiencies. Regarding the offer side, technology neutrality (refarming), better spectrum usage (digital dividend) and authorization of new bands (2,6 GHz) make available a significant spectrum bandwidth for mobile communications. In this article it will be shown how bottom-up long run incremental cost (LRIC) models may help to calculate the economic value of spectrum in terms of improvement of mobile network efficiency, either as a stand-alone tool or integrated in more complex economic models. Importance of short run effects of changes in spectrum allocation are remarked using a case study on 900 MHz band refarming in a typical mobile operator.","PeriodicalId":269841,"journal":{"name":"2010 9th Conference of Telecommunication, Media and Internet","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129042433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have identified several psychological effects through which consumers are believed to be biased towards flatrate plans. However, flatrate plans also limit customers' tariff flexibility in months of low usage. Cost cap tariffs are a hybrid between pay-per-use and flatrate plans and can offer cost insurance while maintaining flexibility. In particular, we provide evidence from a survey among 214 German university students that flexibility, cost insurance and the so-called taximeter effect are the main drivers behind cost cap tariff choice. Furthermore, we show that the insurance and taximeter effects are distinct if evaluated within a flatrate or cost cap tariff framework. Finally, based on our results we also comment on the profitability of cost cap plans from a strategic management perspective.","PeriodicalId":269841,"journal":{"name":"2010 9th Conference of Telecommunication, Media and Internet","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125699063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
