Bidirectional point-to-point communication is carried out on the power-supply wire between the appliance itself and the outlet. Here a dedicated device embeds both network management functions and ULP communication, acting as a proxy between the appliance and the home network. Through this approach, white goods, as well as any other electrical household appliance, can be connected to the home network at extremely low communication cost and with no constraints related to the actual communication protocol choice. In this summary, after a brief introduction, the network structure is presented. Next, physical layer of ULP protocol is discussed and a prototypal HW implementation is presented. Finally, experimental ULP performances are discussed and conclusions are drawn.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128108188","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}

For the synchronization of a distributed system networked using powerline, however, essential modifications are needed in order to cope with the peculiar behaviour of power line as a communication medium. One of these special properties is the non-stable network topology caused by load balancing of the energy suppliers; another is the non-symmetric communication delay, as opposed to the common symmetry assumption in most state-of-the-art synchronization protocols. Finally, it is well understood that high-accuracy clock synchronization needs a very tight coupling of the protocol to the physical layer. This paper investigates a concept for synchronization in a powerline network and describes an approach which is taking advantage of a special clock synchronization hardware working closely together with a powerline physical layer.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125193700","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}

Besides the software implementation of these innovative systems, the investigation of new physical layers is of essential interest and of special interest in this article. Meanwhile the use of the electrical power supply grid as a communications medium has reached a considerable level of quality. Due to this success, it appears rewarding to open further areas of application for the new and innovative powerline technology, e.g. automotive power line communications. This paper investigates the properties of automotive onboard power supply networks for the purpose of an integrated power and data transmission. It is obvious, that the electrical power supply system within an automobile has very few in common with a residential area's supply grid. This means that new and different approaches must be found. This article introduces a brief tutorial about the realization of a vehicular high speed data communication on powerlines.

The range between 3 kHz and 148.5 kHz is regulated by the Norm CENELEC EN 50065 since 1991. It is split into four bands (A, B, C and D) where the upper three bands are open for private use. In order to provide Internet connectivity to practically every household appliance, there are technologies under development, which will use the frequency range between 95 kHz and 148.5 kHz. Unfortunately, the EN 50065 was released with a lack of knowledge about the very specific channel properties of electrical installations. Thus, following the norm, also the EHS-standard and according test procedures (named Orphelec test) of communications equipment adopted the deficiencies to a great extent. In this paper a qualified channel model and its implementation in hard- and software is presented. Further on, a realisation of a channel emulator is given, considering all typical channel properties. Finally, a qualified test procedure providing comparability between different communication systems is introduced.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128240575","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}

In this investigation, we consider realization of QoS for various telecommunications services in networks using reservation MAC protocols, which apply different reservation domains. We investigate possibilities for application of the packet voice service in network models using different reservation domains and compare their performance. We can conclude that the choice of an optimal reservation domain depends strongly on the kind of services for which the reservation is carried out per-packet reservation domain is suitable data services without particular time-critical requirements. On the other hand, per-burst reservation is suitable for data services with higher QoS requirements, such as packet voice service. Therefore, a combination of various reservation principles depending on requested services seems to be a suitable solution for the reservation domain.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132741594","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}

Firstly, the business environment of technological convergence is investigated to search for opportunities to deploy BPL. Additionally, BPL competitiveness is assessed against the main existing access technologies. As a basis for telecom business environment diagnostic, we present the results of a research in Brazil's telecom market to understand how service providers are reacting to technological convergence [Cunha, A., 2001],[Quientella, HLMM, 1997] . The results were compared with a similar US research developed in 1991 by Joseph Pine, MIT. The results indicated that many technological innovations do not reach the market due the lack of appropriated businesses models. Furthermore, a technologic competitiveness assessment is performed using traditional techniques such as Porter's 5 forces [Porter, M, 1980]. BPL/PLC is assessed against the existing access technologies. Some strategic drivers were outlined in the entrance of BPL/PLC in the telecom sector. It provides important insights of how new technological assets, like BPL, can be competitive and integrated into telecom services.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130615125","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}
