ETSI unveils new DECT-2020 radio interface for IoT
The new DECT-2020 New Radio standards address ultra-reliable, low-latency and massive machine-type communication use.

From its origins in the 1990’s, the DECT™ (Digital enhanced cordless telecommunications) standard is implemented in more than a billion short-range communication devices around the world. The technology is now taking a massive step forward with a set of DECT-2020 New Radio (NR) standards. Designated the ETSI TS 103 636 series, these standards define an advanced radio interface applying modern radio technologies and are designed to provide a slim but powerful technology foundation for wireless applications deployed in various use cases and markets.

DECT-2020 NR was developed to support broad and diverse wireless IoT applications requiring both ultra-reliable and low-latency communication needed in voice and industrial applications. It also supports massive machine-type communication with millions of devices in a network required in use cases such as logistics and asset tracking, industry 4.0 and building automation as well as condition monitoring.

ETSI DECT-2020 NR as a technology foundation is targeted for local area wireless applications, which can be deployed anywhere by anyone in no time. The technology enables autonomous and automatic operation with minimal maintenance effort. DECT-2020 NR supports mesh communication, with low latency communication links, enabling massive machine-type communications (mMTC) for industry automation without a need for infrastructure investments. It also supports ultra-reliable low-latency communications (URLLC) for professional wireless audio applications with point-to-point or multicast communications. Thanks to its dynamic channel selection feature, DECT-2020 NR does not require frequency planning and the complexity of this technology is relatively low. The standard has a dedicated global frequency band at around 1900 MHz.

The DECT-2020 NR standard provides high deployment flexibility:

  • Ultra-reliable point-to-point and point-to-multipoint wireless links;
  • Local area wireless access networks;
  • Self-organizing local area wireless access network following a mesh network topology.
