SCHC over NB-IoT
draft-ietf-lpwan-schc-over-nbiot-02
Abstract
The Static Context Header Compression (SCHC) specification describes
a header compression and fragmentation functionalities for LPWAN (Low
Power Wide Area Networks) technologies. SCHC was designed to be
adapted over any of the LPWAN technologies.
This document describes the use of SCHC over the NB-IoT wireless
access, and provides elements for an efficient parameterization.
