Internet of Things


An increasing number of everyday machines and objects are now embedded with sensors or actuators and have the ability to communicate over the Internet. Collectively they make up the Internet of Things (IoT).

Individual devices are connected through Machine-to-Machine (M2M) communications interfaces.

Potential applications and services in the IoT include:

  • smart devices
  • smart cities
  • smart grids
  • the connected car
  • eHealth
  • home automation and energy management
  • remote industrial process control

Standardizing the IoT

Smart objects produce large volumes of data. This data needs to be managed, processed, transferred and stored securely.

The use of standards

  • ensures interoperable and cost-effective solutions
  • opens up opportunities in new areas
  • allows the market to reach its full potential

The more things are connected, the greater the security risk. So security standards are also needed to protect the individuals, businesses and governments which will use the IoT.

Our Role & Activities

A wide range of technologies work together to connect things in the Internet of Things (IoT). ETSI is involved in standardizing many of these technologies:

Machine-to-Machine (M2M) communications

  • ETSI is a member of oneM2M, the global partnership initiative which aims to provide a standardized M2M interface. This will enable different devices to be connected in the IoT, irrespective of the underlying network.
  • The work of oneM2M builds on the activities of our own committee, TC SmartM2M, which has developed, and now maintains, our specifications for a standardized platform:

TC SmartM2M is also addressing IoT standardization gaps identified in European Commission Large Scale Pilot projects.

Applications in the IoT

Within ETSI we are addressing various applications of M2M technology:

Supporting the IoT
