BS PD CLC/TS 52056-8-5:2015规定了用于 基于建议ITU-T G.9901的计量目的:窄带正交 频分复用电力线通信收发器.功率谱 密度规范和ITU-T G.9903窄带正交分频 G3-PLC网络的多路电力线通信收发器，正交 频分复用（OFDM）电力线通信（PLC）协议。物理层提供了一种有效利用允许的 CENELEC A频段内的带宽（3 kHz？95 kHz）（尽管ITU-T G.9903定义了 CENELEC B、ARIB和FCC频段的协议），从而允许使用 先进的信道编码技术。这种组合可以实现非常健壮的通信 在存在窄带干扰、脉冲噪声和频率选择性的情况下 衰减。媒体访问控制（MAC）层允许通过网络传输MAC帧 使用电力线物理通道。它提供数据服务、帧验证控制、， 节点关联和安全服务。6LoWPAN适配子层使MAC和 IPv6网络层。IPv6网络协议；最新一代的IP（互联网协议）， 广泛开放计量用途的潜在应用和服务范围（但不是 仅限于计量目的）。传输层、应用层和数据模型如EN 62056所述 DLMS/COSEM套件。交叉引用:FprEN 62056-4-7:2014IEC 62056-4-7:2015EN 62056-5-3IEC 62056-5-3EN 62056-1IEC 62056-6-1EN 62056-6-2IEC 62056-6-2EN 62056-9-7:2013IEC 62056-9-7:2013ITU-T G.9901:2014ITU-T G.9903:2014IETF RFC 768:1980IETF RFC 2460:1998IETF RFC 4193: 2005IETF RFC 4291:2006IETF RFC 4944IETF RFC 6282购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS PD CLC/TS 52056-8-5:2015 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.Cross References:FprEN 62056-4-7:2014IEC 62056-4-7:2015EN 62056-5-3IEC 62056-5-3EN 62056-6-1IEC 62056-6-1EN 62056-6-2IEC 62056-6-2EN 62056-9-7:2013IEC 62056-9-7:2013ITU-T G.9901:2014ITU-T G.9903:2014IETF RFC 768:1980IETF RFC 2460:1998IETF RFC 4193:2005IETF RFC 4291:2006IETF RFC 4944IETF RFC 6282All current amendments available at time of purchase are included with the purchase of this document.
