Low Throughput Networks

Machine-to-Machine communications and the Internet of Things (IoT) involve the connection of potentially billions of connected objects which need only low throughput connectivity.

The anticipated benefits of creating new dedicated IoT Low Throughput Networks (LTN) include:

  • lower costs
  • the creation of new applications
  • a reduction in electromagnetic radiation by improving data transmission efficiency

LTN are expected to be crucial to the success of IoT standardization and implementation, and to provide the basis for many new and innovative applications.

We set up an Industry Specification Group on Low Throughput Networks (LTN) in 2012 [closed now]. Its task was to specify a new ultra narrowband radio technology for very low data rates for ultra long autonomy devices.

In 2014, the group completed three ETSI Group Specifications on:

  • LTN use cases
  • a dedicated architecture
  • interfaces and protocols

Together these specifications provide the foundation for mainstream standardization work which is now being undertaken in our Electromagnetic Compatibility and Radio Spectrum Matters committee (TC ERM).

TC ERM is developing LTN use cases and system requirements and specifying the LTN architecture and the protocols for LTN interfaces.
