This part of IEC 62056 describes the use of DLMS ® / COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMS ® / COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN. This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN. Low-Power Wide Area Networks (LPWANs) are wireless technologies with characteristics such as large coverage areas, low bandwidth, possibly very small packet and application-layer data sizes, and long battery life operation. This document does not provide functionality to manage the lower layers of the LPWANs. This part of the DLMS ® / COSEM suite specifies the communication profile for Low-Power Wide Area Networks (LPWANs). The DLMS ® / COSEM LPWAN communication profiles use connection-less transport layer based on the Internet Standard User Datagram Protocol ( UDP ) and Internet Protocol (IPv6). The adaptation layer is based on IETF RFC 8724 which provides both a header compression/decompression mechanism and an optional fragmentation/reassembly mechanism. SCHC compression is based on static context with small context identifier to represent full IPv6/ UDP / COSEM wra...
