An inherent benefit of PLC is its ability to work without any additional transmission infrastructure as it uses the existing power line cabling. Moreover, with the development of general-purpose PLC chip sets, the cost of designing and employing PLC systems is continuously reducing. The objective of this paper is to investigate some practical design and implementation aspects of a high-rate PLC-based home network. We start by giving an overview of some general properties of the investigated PLC system proceeding thereafter to have a more detailed discussion on the related circuit technology. We have developed a custom software to investigate network performance, that we then apply to estimate round-trip characteristics by TCP and UDP protocols to compare the developed PLC network to standard Ethernet. Our results indicate that the PLC technology is indeed a worthwhile alternative for high rate, cost-efficient home networking.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"18 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":"115226787","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}

The path amplitude and arrival-time distributions are investigated, as well as ranging of the RMS-delay-spread. Specific analogy between the simplified topology and real indoor power-line network structures is hereupon introduced. The evaluation is performed via comparative simulation between channel routes of a real in-house network and the corresponding branched-bus configurations. A novel computational simulation tool is to this effect employed. Qualitative suitability of the examined topology is indeed verified, and quantitative deductions are extracted as well.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"64 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":"114418501","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}

Impulse noise is one of the main channel impairments in the power-line channel. One way to combat impulse noise is to detect the presence of the impulses and to declare an erasure when an impulse occurs. In this paper, we propose a coding system based on irregular low-density parity-check (LDPC) codes and bit-interleaved coded modulation. We show that by carefully choosing the degree distribution of the irregular LDPC code, both the additive noise and the erasures can be handled in a single code. We show that the proposed system can perform close to the capacity of the channel and for the same redundancy is significantly more immune to the impulse noise than the existing methods based on an outer Reed-Solomon code.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"3 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113932806","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 paper describes experiences with implementing three power line carrier communications (PLCC) technologies since 1995 for linear and center pivot automatic agricultural sprinkler systems. Experiences with two additional technologies are also discussed but have not been implemented in the field. The power line characteristics are investigated to show why the power distribution method is favorable to power line carrier communications regardless of loading and switching of loads for speed and direction control. The PLCC connected nodes mounted on the moving center pivot lateral also function as bridges to a wireless network that allows communications with sensors distributed around the field. A protocol that can be used with power line carrier adds flexibility and provides connectivity to nodes not accessible over the power line.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"45 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":"130900931","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}

Bmiller","doi":"10.1109/ISPLC.2005.1430533","DOIUrl":"https://doi.org/10.1109/ISPLC.2005.1430533","url":null,"abstract":"The narrow band power-line communication market is very interesting for utility services, automation, building facilities and so on. The available bandwidth is limited and data rates of several Mbps will not be possible. But the frequency range below 500 kHz has a lot of advantages. The EMC problems are very small compared with BPLC [Harald Dalichau, 2001]. The situation for regulation with CENELEC and FCC is much better. Independent use of the same medium and interoperability with BPLC is possible. The attenuation of the cables and the branches are much lower [Manfred Zimmermann] and it is possible to reach for example distances of 60 km (offshore umbilical cord) without any repeater. This is very important, if we look for reliable systems with a complete coverage of an area and real time requirements. Too much repeaters increase the costs, complicate the network management, reduce the reliability and limit the real time possibilities. Due to it IAd decided to produce two chip sets for this kind of market. The first concept for these chipsets was already presented on the 5th ISPLC in Malmo. Meanwhile, the design of the chipsets is ready, emulation boards with engineering samples of the analog ASIC and a complete design of the digital chip in an FPGA are built, software tools for diagnostic and test are implemented and all is in use for evaluation and first field trials. During the design we spent a lot of effort into the integration of measurement tools to analyse disturbers and characterise the transmission channel without any external measurement equipment. As in the past IAd is the expert for difficult power-line channels and therefore, we define our goal for the development as: 'if it is possible to communicate over a channel, our system has to do it' and this is equal to 'there never should be a system, which is able to communicate, but our one not.' Only if we deliver the best quality we get the confidence of our customer. If problems happen in the field we have to present the way, how to analyse the source of the problem and deliver solutions without additional costs. To reach this goal in the field, the integrated diagnostic is an important part.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"55 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":"122517788","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}
