The use of power line connected to the Internet Feasibility Analysis

Currently, Internet operators are to promote broadband Internet access projects, are taking XDSL lines or a traditional way of integrated wiring network equipment. Radio, Film and Television department is to take HFC network transformation + Cable Modem more expensive measures. These are long construction period, and very inflexible, inconvenient huge one-time investment. It makes the building square miserable when necessary re-wiring and additional network equipment and modification or expansion will be added to the network. In less developed areas, this is more difficult to implement because of shortage of funds However, the use of power line networking technology to access the Internet, it is a more economical and practical options.

1, technical feasibility:Power line networking technology has become more sophisticated, and follows the United States Home plug1.0.1 industry standard. After nearly two years of R & D and field testing, both at home and abroad have launched dozens of professional manufacturers using Intellon chip power line networking products.Most of these products meet the HomePlug 1.0.1 standard specified in the normative, interoperability, operational stability, without interference, the system reliability, application of universal, reliable diagnosis and maintenance requirements can be met, played a variety of standard features, including peer-to-peer file transfer, multi-point file transfer, VOIP (voice) and multimedia (video) transmission.And the use of terminal equipment with access between the flexible and diverse ways, such as RJ45 Ethernet interface, USB interface and wireless interface, etc., can be widely used in broadband network or an extension of the original network, such as IP telephones, computer networks, games, digital television network, optimizing the distribution of digital audio, created the office and teaching, entertainment, automation and reliable platform.

2, practical feasibility:NationalElectricityPowerCompanyStateCommunicationsCenter in early 2001 to promote the establishment of a power line communication office to the unified management, testing and promotion of PLC technology.In order to test whether the PLC technology in the Chinese low-voltage distribution line is applicable, China PLC office in September 2001 in the State Power Corporation PLC living quarters set up a laboratory, domestic and foreign organizations, nearly ten PLC manufacturers products, respectively PLC network equipment Localization Testing.Over the past year, the pilot network stability, the use of household electrical appliances will not affect the basic Internet access; you can smooth data and multimedia video transmission, the user well.

3, Product feasibility:Apart from Europe and the United States dozens of PLC products, this company HomePlug1.0.1 follow industry standards, the use of Intellon chips, has successfully developed cost-effective power-line broadband access products, various technical indicators have reached the HomePlug1. 0.1 standards and compatible with domestic low-voltage distribution network compatibility, specific description is as follows:

(1) power-line bridgethe device is an Ethernet connection for network and power LineBridge. Products built a high-frequency power line communication module and a 10/100M adaptive Ethernet module, its role is similar to network equipment in the HUB, through the power line can be daisy-chained communication terminals 20-30.Can use it to bridge the existing Ethernet and power line networks, Ethernet and power line networks build two-One Net. As long as you can add this bridge, which will be required at power-line Ethernet network and the original mixed-use environment

Product Features

Energy and data transmission technology with the line, so that power supply equipment has been at the same time can be required of the data transmission

Machine energy priorities and data separation technology to ensure data transmission products will absolutely not compete with high-pressure contact

Built-in high-performance processors, competent users of complex applications

PLC Modem users with links to the home power socket, through the power line distribution box connected to the building of the PLC-side bridge, bridges and telecommunications connectivity broadband access equipment to complete network. Users only need to be PLC-Modem plug in the power socket on the internal LAN access and Internet access across the network.

The whole system of simple structure, easy installation, and the entire construction period without holes through walls Antinomies only required at a few weak wells emplaced bridge connecting the root of the vertical cable, in the hallway on each floor and the room is no need for any level of circuit laying.
