It offers compression and fragmentation of IPv6/UDP/CoAP packets to allow their transmission over the Low-Power Wide-Area Networks (LPWAN).
Low-Power Wide-Area Network (LPWAN) gathers the connectivity technologies tailored for Internet of Things (IoT), allowing for: The trade-off for achieving these features includes severe limitation in terms of throughput and packet size supported.
The Generic Framework for Static Context Header Compression and Fragmentation, RFC 8724 has been published in April 2020.
Additional work is dedicated to the definition of standard parameter settings and modes of operation to optimize SCHC's performance according to the implemented protocols and the underlying LPWAN technologies: On May 17, 2022, The LoRa Alliance (global association of companies backing the open LoRaWAN® standard for the internet of things low-power wide-area networks) announced that LoRaWAN now seamlessly supports Internet Protocol version 6 (IPv6) from end-to-end.
[7] In addition, SCHC is being adopted in a joint standardization effort carried out by the DLMS User Association and the LoRa Alliance for the smart metering industries.
