Extending the power line LAN up to the neighborhood transformer

International Symposium on Power Line Communications and Its Applications, 2005., 2005

Nowadays the interest in transmitting video over home networks increases rapidly and services like video on demand are getting more attention. This article starts by providing an overview of the power line communication technology. Then the article presents the results of series practical measurements of the throughput, the response time, the transaction rate and the quality of different kinds of video streams, including real time video and kinds of video files, over the power line network at different locations in rooms of the research lab at the University of Leeds. Following that, a comparison between power line network and other networks serving as the backbone of home network to transmit video signals is given. Finally, a discussion of the feasibility of distributing digital TV signals over home power line networks and a brief description of market perspectives and promising applications are included.

This is to certify that the thesis entitled-Application of Ethernet over Powerline Communication‖ submitted by Jami Aditya (109EC0314) and Priyanka Priyadarsini (109EC0177) in partial fulfillment of the requirements for the award of Bachelor of Technology Degree in Electronics and Communication Engineering at National Institute of Technology, Rourkela is an authentic work carried out by them under my supervision and guidance.

This paper presents a channel model suitable for multiwire overhead medium voltage lines. This model, incorporating ground admittance, is more appropriate at higher frequencies than predicted by Carson's model of 1926. The proposed model is further used to evaluate the multipath channel impulse response and associated capacity limit in sample power distribution grids for applications in broadband over power lines communications. For a sample grid model, comparison is made to the capacity value predicted based on the Carson's model, and it is demonstrated that the older model underestimates the potential of the overhead lines for broadband transmissions, significantly.

The Power Line at homes usually consists of external wiring or wireless, both are complicated and expensive. Power line communication has been around for quite some time, but been used for Narrow band tele remote relay applications, public lighting and home automation. Power Line communications basically means any technology that enables data transfer at narrow or broadband speeds through power lines by using advanced modulation technology. A prototype has been designed for power line communication using audio as an input signal at the receiver. Transmitter/Receiver module has been designed which is capable of controlling the signal and transferring it to the receiver side without any external wiring. The control signals is send on the power line using transmitter and all the appliances on that phase are able to sense that signal using receiver. The internal circuitry works on frequency modulation technique for digital data transmission generated by microcontrollers. Each module has...

Low voltage electrical wiring has largely been dismissed as too noisy and unpredictable to support high-speed communication signals. Advances in communication and modulation methodologies as well as in adaptive digital signal processing and error detection and correction have spawned novel protocols capable of supporting power line communication networks at speeds comparable to wired LANs. We motivate the use of power line LANs as a basic infrastructure for building integrated smart homes, wherein information appliances ranging from simple control or monitoring devices to multimedia entertainment systems are seamlessly interconnected by the very wires that provide them electricity. By simulation and actual measurements using "reference design" prototype commercial powerline products, we show that the HomePlug MAC and PHY layers can guarantee QoS for real-time communications, supporting delay-sensitive data streams for smart home applications.

We address the challenges related to the development of very high speed power line communication (PLC) systems in the home environment. The development of such a technology is fundamental to realize the objective of reliably delivering new high speed services in the home environment in a network that integrates in a coordinated fashion also wireless systems. That is, an in-house network with the need of "no new wires". We start with an overview of the state of the art PLC technology, and then we describe our vision on application scenarios, and requirements. We address the problem related to transmission bandwidth, channel modeling, capacity evaluation as well as we describe novel advanced transmission technologies that enable reliable high speed transmission. We show that by enhancing current technology bandwidth up to 100 MHz, Gbps transmission is achievable.

2007 Innovations in Information Technologies (IIT), 2007

We give an overview of the Power Line Communications (PLC) technology, its importance, its standards and an overview of the HomePlug standards associated with it. This is done is two parts due to publication constraints. In this part, we will concentrate on the PLC applications and the technical issues regarding it. We will also see the layers and methods that are needed to make it work.

Power Line Communication uses the existing power lines within a home, building or an outdoor power distribution network to transmit data from one device to another. With a well-designed power line solution, devices should be able to communicate using the existing wiring infrastructure. This makes power line communication one of the most cost-effective means for networking devices. But as power lines were designed to carry power and not data, it takes a very sophisticated transceiver to reliably communicate over power lines. Many electrical devices connected to the power lines adversely impact the data that is being transmitted.

This study is conducted after perceiving the lack of gathered information and relatively new research and development on the usage of Voice over Internet Protocol (VoIP) through an existing infrastructure of electrical wires known as VoIP using Power Line Communications (PLCs). The primary purpose of the PLC is the delivery of AC (50 Hz or 60 Hz) or DC electric power. PLCs system operate the largest existing network in the world, which is the electrical distribution grid and therefore can establish communication networks for data transmission. Five experimental studies are implemented on Home Area Network (HAN) to test the efficiency of the proposed system and a comprehensive presentation dealing with the different aspects of VoIP over power lines are discussed.

In this paper a survey of power line communications has been presented. As power line distribution networks are available in almost each building that is mainly used for the supply of electrical power, it will be very interesting if such media could be used for the transmission of data. The demand of low cost telecommunication, broadband and access to internet services is increasing day by day and applied a driven force leading to further research in the field of power line communications. A number of organizations are working on power line communications and more advanced schemes are being proposed so that a new dimension could be added to the potential application of established wire line infrastructure.
