21、 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 advance

22、d 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 c

23、hannel. 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 th

24、e 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. 2 Normative references The following documents, in whole or in part, are norma

This technical specification

38、has been developed to meet the following aims: Robustness: the communication profile shall be suited to severe powerline environments; Performance: it embeds adaptive modulation to use the proper modulation according to the quality of the link; Simplicity: it shall be simple to implement, install (P

39、lug and Play), operate and maintain; Flexibility: it shall be compatible with diverse applications and network topologies; Security: it shall offer a secure environment for the promotion of Value Added services; Openness: it shall be based on open standards in order to support multi-supplier solutio

40、ns; Scalability: it shall support a very large range of devices (from 2 up to 2000 nodes in the same PAN); Future proof: it shall be able to support future applications. 6 Targeted communication environments The DLMS/COSEM narrow-band OFDM PLC profile for G3 networks is intended for remote data exch

43、devices typically electricity meters comprise application functions and communication functions. They may be connected directly to the NNAP via the C interface, or to an LNAP via an M interface, while the LNAP is connected to the NNAP via the C interface. The LNAP function may be co-located with the

44、 metering functions. A NNAP comprises gateway functions and it may comprise concentrator functions. Upstream, it is connected to the Metering Head End System (HES) using suitable communication media and protocols. End devices and LNAPs may communicate to different NNAPs, but to one NNAP only at a ti

45、me. From the PLC communication point of view, the NNAP acts as the PAN coordinator while end devices and LNAPs act as PAN devices. NNAPs and similarly LNAPs may communicate to each other, but this is out of the scope of this Technical Specification, which covers the C interface only. When the NNAP h

46、as concentrator functions, it acts as a DLMS/COSEM client. When the NNAP has gateway functionality only, then the HES plays the role of a DLMS/COSEM client. The end devices or the LNAPs play the role of DLMS/COSEM servers. A mixed architecture is also possible, i.e. both the HES and the NNAP can act

47、 as a client. 7 Reference model The proposed protocol stack uses the following OSI layers as shown in Figure 2: PD CLC/TS 52056-8-5:2015CLC/TS 52056-8-5:2015 10 COSEM Application Process IEC 62056-6-1/6-2 COSEM Application layer IEC 62056-5-3 WRAPPER IEC 62056-4-7 PLC Media Physical layer ITU-T G.99
