Technical Committee (TC) Smart Machine-to-Machine Communications (SmartM2M) Activity Report 2020

Chair: Enrico Scarrone, Telecom Italia S.p.A. 

Responsible for providing specifications for Machine-to-Machine (M2M) services and applications, including the Internet of Things (IoT) and smart cities.

M2M (Machine-to-Machine) communications are the foundations for a fast-emerging world of smart devices, appliances, homes and communities.

As the main Technical Body representing ETSI in the oneM2M Partnership Project, our Smart M2M Communications committee (TC SmartM2M) creates reports and specifications for M2M services and applications, with much of its work focusing on the IoT and smart cities. In coordination with oneM2M, TC SmartM2M helps produce specifications that enable users to build platforms that allows devices and services to be connected, regardless of the underlying technology used.

The wide scope of SmartM2M’s interests sees it interacting with several other ETSI Technical Bodies and projects, including ITS, CIM, SmartBAN, eHEALTH, EMTEL, CYBER and E4P.

The committee’s work enables connected devices to exchange information through SAREF, ETSI’s Smart Applications REFerence ontology that runs with oneM2M-compliant communication platforms. Providing building blocks that allow separation and recombination of different parts of the ontology depending on specific needs, SAREF specifies recurring core concepts in the smart applications domain and the relationships between them.

During the year our SAREF ontology was enhanced with four further extensions (Automotive TS 103 410-7, eHealth/Ageing-well TS 103 410-8, Wearables TS 103 410-9 and Water TS 103 410-10 domains). Complementing these, we revised six existing SAREF extensions (Energy TS 103 410-1, Environment TS 103 410-2, Building TS 103 410-3, Smart Cities TS 103 410-4, Industry & Manufacturing TS 103 410-5, and Smart Agriculture and Food Chain TS 103 410-6 domains).

We also published new guidelines SR 003 680 for security, privacy and interoperability in IoT system definition based on the analysis of representative use cases.

A Technical Report TR 103 546 explored the requirements for collecting and exchanging data between smart lifts, their management applications and their interaction with other IoT devices in a building environment.

 A ‘Proof-of-Concept’ for AI and oneM2M – published as TR 103 675 – examines the potential of Artificial Intelligence (AI) and Machine Learning (ML) solutions within various IoT systems and applications.

As part of ETSI’s New Working Methods initiative, 2020 marked the launch of the official ETSI portal for SAREF, giving user communities direct links to SAREF ontologies and SAREF-related work items. See the latest SAREF core, extensions, specifications and documentation at

During the year we continued to participate in joint CEN/CENELEC/ETSI coordination groups on smart meters, smart energy grids and smart manufacturing.

Under the leadership of our Centre for Testing and Interoperability, SmartM2M continued its contribution to a set of standardized conformance test specifications (Test Suite Structure and Test Purposes and Abstract Test Suite) for oneM2M architecture and core protocols.
