As specified in the DLMS communication profile for LPWAN, the SCHC compression encodes the 48 bytes of IPv6/UDP headers and the 8-byte DLMS wrapper within a rule ID of 1 to 3 bytes, representing a header-compression ratio of 90%.
The profile also implements the SCHC fragmentation that dynamically adapts packet size up to the Maximum Transmission Unit (MTU, from 51 to 242 bytes in LoRaWAN). Thus, SCHC ensures operations in all data rate conditions, and guarantees to take advantage of the connectivity’s full capacity.
Acklio takes SCHC optimization two steps further, also applying compression to DLMS/COSEM payload (downlink HES queries and uplink metering data). In this case, Acklio SCHC achieves 75% compression rate on the whole IPv6/UDP/DLMS packet.
