Static Context Header Compression (SCHC) is a compression and fragmentation mechanism that enables the use of internet protocols over low power, wide area networks (LPWAN).

Resulting from the common work carried out by Acklio and IMT Atlantique, SCHC opens new horizons for the Internet of Things (IoT) and accelerates LoRaWAN® adoption. Historically, most Internet standards were too complex for LPWAN environments. IoT technologies and use cases were not interoperable and it was challenging to integrate them with existing architectures.
