Electricity metering data exchange - The DLMS/COSEM suite - Part 8-5: Narrow-band OFDM G3-PLC communication profile for neighbourhood networks

This Technical Specification specifies the EN 62056 DLMS/COSEM communication profile for metering purposes based on the Recommendations ITU-T G.9901: Narrowband Orthogonal Frequency Division Multiplexing Power Line Communication Transceivers – Power Spectral Density Specification and ITU-T G.9903 Narrow-band orthogonal frequency division multiplexing power line communication transceivers for G3-PLC networks, an Orthogonal Frequency Division Multiplexing (OFDM) Power Line Communications (PLC) protocol. The physical layer provides a modulation technique that efficiently utilizes the allowed bandwidth within the CENELEC A band (3 kHz – 95 kHz) (although ITU-T G.9903 defines the protocol for CENELEC B, ARIB and FCC bands as well), thereby allowing the use of advanced channel coding techniques. This combination enables a very robust communication in the presence of narrowband interference, impulsive noise, and frequency selective attenuation. The medium access control (MAC) layer allows the transmission of MAC frames through the use of the power line physical channel. It provides data services, frame validation control, node association and secure services. The 6LoWPAN adaptation sublayer enables an efficient interaction between the MAC and the IPv6 network layers. The IPv6 network protocol; the latest generation of IP (Internet Protocol), widely opens the range of potential applications and services for metering purposes (but not limited to metering purposes). The transport layer, the application layer and the data model are as specified in the EN 62056 DLMS/COSEM suite.

Introduction
This Technical Specification is based on the results of the European OPEN Meter project,
Topic Energy 2008.7.1.1, Project no.: 226369, www.openmeter.com, and prepared by G3
Alliance, www.g3-plc.com.
1 Scope
This Technical Specification specifies the EN 62056 DLMS/COSEM communication profile for
metering purposes based on the Recommendations ITU-T G.9901: Narrowband Orthogonal
Frequency Division Multiplexing Power Line Communication Transceivers – Power Spectral
Density Specification and ITU-T G.9903 Narrow-band orthogonal frequency division
multiplexing power line communication transceivers for G3-PLC networks, an Orthogonal
Frequency Division Multiplexing (OFDM) Power Line Communications (PLC) protocol.
The physical layer provides a modulation technique that efficiently utilizes the allowed
bandwidth within the CENELEC A band (3 kHz – 95 kHz) (although ITU-T G.9903 defines the
protocol for CENELEC B, ARIB and FCC bands as well), thereby allowing the use of
advanced channel coding techniques. This combination enables a very robust communication
in the presence of narrowband interference, impulsive noise, and frequency selective
attenuation.
The medium access control (MAC) layer allows the transmission of MAC frames through the
use of the power line physical channel. It provides data services, frame validation control,
node association and secure services.
The 6LoWPAN adaptation sublayer enables an efficient interaction between the MAC and the
IPv6 network layers. The IPv6 network protocol; the latest generation of IP (Internet Protocol),
widely opens the range of potential applications and services for metering purposes (but not
limited to metering purposes).
The transport layer, the application layer and the data model are as specified in the EN 62056
DLMS/COSEM suite.
