International. The Internet Engineering Task Force (IETF) has released a key new standard for IoT. This technology, called SCHC, allows the use of IP-based protocols in IoT networks. Ensures interoperability between LoRaWAN, Sigfox, NB-IoT and LTE-M technologies. More importantly, using this standard ensures the longevity of IoT deployments by making them extensions of the Internet.
After 4 years of effort, the IETF, the organization behind the standardization and evolution of Internet protocols, has published a new structuring technology for the IoT market. This new international standard, called SCHC (pronounced "chic") for static context header compression, is an advanced mechanism for fragmenting and compressing Internet stack headers. Allows restricted devices connected to LPWAN networks to communicate over IP.
SCHC offers a native adaptation of existing IP-based protocols to LPWAN networks. By avoiding the development of ad-hoc bespoke solutions, as well as the associated testing, integration and support, the effort to bring existing business solutions to LPWAN is now estimated in days, not years.
In addition, the use of IP protocols facilitates the integration of the network, since they transport the messages throughout the chain. It can speed up the development of services, as developers work with familiar tools. In addition, the use of standard security solutions can improve and add consistency to security policy across IT. And above all, the application becomes independent of the radio technology used.
Several initiatives are now flourishing to reap the benefits of SCHC. For example in the utility market. The LoRa Alliance and DLMS Association have worked together to specify a standardized stack for data exchange with smart meters: DLMS over LoRaWAN using SCHC as an adaptation layer.
