  This part of [IEC 62056](/search?q=IEC%C2%A062056)
   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...
