Smart Grid ICT and Spectrum Optimization: Technologies and Markets
PracTel Inc, April 2011, Pages: 180
The scope of Smart Grid ICT complexity and required bandwidth are currently only generically outlined. The report shows that despite of the current perception to consider this type of communications as low-bandwidth, in reality it may require many millions of new communications channels with the speed of transmission in Mb/s. This can create a serious problem in already congested RF spectrum. The industry is working to resolve such a problem; and responds with new technologies that can utilize unused spectrum (for example, TV White Space -TVWS) as well as cognitive radio.
The objectives of this report were to show the role of ICT in the support of the Smart Grid infrastructure; and introduce some trends in the ICT development.
Particular, the report addresses the following:
Section I -Introduction. It explains the major Smart Grid goals and provides examples of developments.
Section II – Provides detailed Smart Grid background. The activities of multiple Smart Grid associations and industry organizations are covered.
Section III – Provides marketing and technological analysis of the Smart Grid ICT; industry characteristics and Smart Meters developing. The surveys of products portfolios of major industry players are provided.
Section IV - Prepares an audience to better understand the specifics of the SUN. Such a network, as it is envisioned currently, may include Software Defined radio (SDR) or its enhanced version – Cognitive Radio (CR). The wireless SUN may consume a lot of bandwidth (though the end-user transmission may use only up to 1 Mb/s data streams). Taking into consideration millions of such lines, the introduction of Smart Grid end-users may create a serious problem in the already congested wireless communication spectrum; CR can sense frequency spectrum and optimize its use. SDR technologies and markets are addressed.
Section V provides the analysis of evolving standards, including IEEE 802.11af, IEEE 802.15.4g and IEEE 802.22 (as well as other); some of them may utilize TV White Space communications as well as CR and play a significant role in the developing of effective Smart Grid ICT.
Section VI – Conclusions.
The report also contains Appendix, which details specifics of TVWS communications.
This report is written for wide audience of technical and managerial staff that is involved in the development of Smart Grid ICT.
Target Audience:
This report is important to a wide population of researches, technical and sales staff involved in the developing of the Smart Grid ICT and particular in SUN. It is recommended for both service providers and vendors that are working with related technologies. The report also helps to understand issues associated with relationship between “green” Smart Grid ICT and other technologies.
Research Methodology:
Considerable research was done using the Internet. Information from various Web sites was studied and analyzed. Evaluation of publicly available marketing and technical publications was conducted. Telephone conversations and interviews were held with industry analysts, technical experts and executives. In addition to these interviews and primary research, secondary sources were used to develop a more complete mosaic of the market landscape, including industry and trade publications, conferences and seminars.
The overriding objective throughout the work has been to provide valid and relevant information. This has led to a continual review and update of the information content.
