Exploiting Gigabit Powerline Communications

家庭网络允许连接在同一网络上的不同设备相互通信。日常生活中计算机之间的交互越来越多，这增加了对提高家庭网络在带宽和安装简易性方面性能的需求。因此，我们建议现在将高频电力线通信(PLC)技术商业化，该技术通过配电电缆传输非常高的数据速率信号，这是最近由EPSRC资助的伦敦大学玛丽女王学院(QMUL)项目开发的。PLC消除了对数据传输专用电缆的需要，并且已经显示出其潜力，不仅在家庭/办公室网络领域，在家庭/办公室网络领域，需要可靠的高数据速率链路来连接各种电子设备和计算机，还在诸如列车车厢上的闭路电视的视频流以及在无线链路和其他技术失效的高电磁干扰环境中维护数据链路等领域。现有的PLC技术只能以高达200 Mbps的速率传输数据。这不足以流畅运行各种多媒体应用程序，例如在线视频游戏、数字音频流和高清晰度电视(HDTV)流。玛丽皇后开发的技术允许数据速率高达1Gbps，并支持上述媒体应用程序和其他如视频点播(VoD)和基本局域网连接。我们的商业想法是基于我们开发的底层技术开发一个商业原型，与传统的PLC和其他无线技术相比，该原型允许在高频段(50-550 MHz)的电力电缆上进行高数据速率传输，并为家庭/办公室网络和其他环境中日益增长的高数据速率链路提供简单、灵活和廉价的解决方案。拟议的项目从一开始就受益于工业界的支持。在ESPRC资助的项目中，我们与超宽带(UWB)无线公司Artimi Ltd(英国)和电力线通信公司SiConnect Ltd进行了合作。我们还与一家名为COE有限公司的安全设施公司合作，该公司对列车闭路电视数据链路技术的开发感兴趣。另一家公司，电力线技术有限公司，也表达了他们在被强烈电磁干扰污染的环境中开发数据链路技术的兴趣(例如，连接工厂中的设备以实现灵活的计算机辅助制造)。我们打算与玛丽皇后创新有限公司(QMUL的技术转移办公室)合作，将技术授权给这些客户，并发展进一步的产业关系机会。

Home networking allows different devices connected on the same network to communicate with one another. The increasing interaction between computers in our daily life has increased the demand for improved performance of home networks in terms of bandwidth and ease of installation. We therefore propose to now commercialise a high frequency powerline communication (PLC) technology that transmits very high data rate signals over electrical power distribution cables that has been recently developed in an EPSRC funded project at Queen Mary, University of London (QMUL). PLC eliminates the need for dedicated cables for data transmission, and has already shown its potential not only in the area of home/office networking, where a reliable high data rate link is desired for the connection of various electronic devices and computers, but also in areas such as the video streaming of CCTVs on train carriages and maintaining data links in high electromagnetic interference environments where wireless links and other technologies fail.Existing PLC technologies can only transmit data at a rate up to 200Mbps. This is not sufficient for the smooth running of various multimedia applications such as online video gaming, digital audio streaming, and high-definition TV (HDTV) streaming. The technology developed at Queen Mary allows data rates of up to 1Gbps and supports the afore-mentioned media applications and others such as Video on Demand (VoD) and basic LAN connections. Our business idea is to develop a commercial prototype, based on the underlying technology we have developed, that allows high data rate transmission (up to 1Gbps) over the power cables in the high frequency band (50 - 550MHz) and provides a simple, flexible and cheap solution for the increasing demand of high data rate links in the home/office networking and other environments, compared with the traditional PLC and other wireless technologies. The proposed project has benefited since its beginning from the support from industry. We have worked with Artimi Ltd (UK), an ultra-wideband (UWB) wireless company and SiConnect Ltd, a powerline communication company in the ESPRC funded project. We have also worked with a security facility company, COE Ltd, who is interested in the exploitation of the technology for the data link of CCTVs on trains.. Another company, Powerline Technologies Ltd, has also expressed their interest in exploiting the technology for data links in environments contaminated by strong EM interference (e.g. connecting equipment in factories for 'flexible computer-aided manufacturing'). We intend to work with Queen Mary Innovation Ltd, the Technology Transfer Office at QMUL to licence the technology with these customers and develop further industrial relationship opportunities.
