First-of-its-kind publication features ITU-T standards for smart grid and home networking

ITU-T experts, Stefano Galli and Erez Ben-Tovim, are among the co-authors of a new book titled “MIMO Power Line Communications: Narrow and Broadband Standards, EMC, and Advanced Processing”, edited by Lars T. Berger, Andreas Schwager, Pascal Pagani and Daniel M. Schneider. The work is considered one of the first of its kind, offering a comprehensive guide to the technologies and standards underlying present-day power line communications (PLC).

Part III of the five-part publication, “Current PLC Systems and Their Evolution”, provides a detailed description of current narrow- and broadband PLC standards; in large part thanks to the contribution of experts working in ITU-T Study Group 15 (Transport, Access and Home).

Stefano Galli, ITU-T’s lead expert on smart grid communications, is co-author of Part III’s opening chapter surveying current PLC systems. Galli is also co-author of a chapter dedicated to narrowband PLC standards, in particular ITU-T’s family of orthogonal frequency-division multiplexing (OFDM)-based narrowband PLC standards, Recommendations ITU-T G.9902, G.9903 and G.9904, as well as IEEE 1901.2.

The ITU-T broadband PLC standard (ITU-T G.996x-series) is a suite of broadband home-networking Recommendations which also form the subject of a dedicated chapter authored by Erez Ben-Tovim, another active contributor to ITU-T work.

Following the description of ITU-T’s home-networking standards, Part III contains chapters focused on IEEE 1901 and HomePlug AV2, concluding with an introduction to hybrid systems based on IEEE 1905.1 which combine PLC with other wireless and wireline technologies.

About the publication and ITU-T expert contributors

Multiple-input multiple-output (MIMO) techniques are gaining in importance for power line channels – traditionally regarded single-input single-output (SISO) channels – as rising demand for higher data rates and multi-user support is driven by intensified home-entertainment and communication needs, the increasing volume of intelligent devices becoming part of the emerging smart grid, and the accelerating growth of the Internet of Things (IoT).

The publication intends to act as a reference document or handbook, drawing expert input from industry and academia so as to provide a pragmatic understanding of the workings of PLC technologies as well as a scientific basis for ongoing R&D activities.

The book is composed of five overarching Parts sub-divided into self-contained Chapters, all extensively cross-referenced to allow for a flexible reading path. The contents are briefly summarized as follows:

  • Part I: Power Line Channel and Noise: Characteristics and Modelling
  • Part II: Regulations, EMC and MIMO Capacity
  • Part III: Current PLC Systems and Their Evolution
  • Part IV: Advanced PHY and MAC Layer Processing
  • Part V: Implementations, Case Studies and Field Trials

Stefano Galli is Director of Technology Strategy with ASSIA, Inc. and leads ITU-T’s smart-grid standardization work in his role as Rapporteur for Question 15: Communications for Smart Grid, a task team of ITU-T Study Group 15. He is an IEEE Fellow and is also an active contributor to other standardization bodies including Broadband Forum, ETSI NFV, and IEEE.

Erez Ben-Tovim is a Senior Systems Engineer with Sigma Designs and is an active contributor to ITU-T work as an Associate Rapporteur for Study Group 15’s Question 18: Broadband in-premises networking. Ben-Tovim was central to the development of (ITU-T G.996x-series), a suite of standards which provides broadband home-networking over telephone wiring, coaxial cable and power line wiring.​​​​ He is also an active contributor to other standardization bodies including Broadband Forum, IEEE and ETSI.
