ETSI publishes first specification for Ultra Low Energy DECT aimed at the M2M market
ETSI has published the first Technical Specification (TS 102 939-1) on DECT ULE (Ultra Low Energy), a low power consumption radio technology intended for home automation and other Machine-to-Machine (M2M) applications.

DECT ULE is based on the very popular Digital Enhanced Cordless Telecommunications (DECT) standard, which was developed by ETSI. The main characteristics of DECT ULE are ultra-low power consumption, good Quality of Service (a unique feature of ULE compared with other low power wireless standards) and wider coverage than competing technologies.

ULE positions DECT in new and rapidly growing market segments of M2M communications, including energy and utilities (for home automation and smart metering), assisted living and telecare (for example when used with monitoring devices) and safety and security (such as voice entry phones and smoke sensors). The DECT ULE specification is a multi-part specification; the first phase of development has focused on the Home Automation Network (HAN) but ongoing work will extend its application to industrial automation too.

DECT ULE is well suited to support M2M in the home and new ULE devices will be fully compatible with existing DECT systems and will use the existing DECT spectrum. In addition, a single device can combine ULE and DECT/DECT New Generation functionalities. So, by upgrading the base station, existing devices can still be used and other devices added to provide new services and applications to the customer, all controlled from the DECT base station.

DECT ULE harnesses all the advantages of traditional DECT. These include the key factor of instantaneous dynamic channel selection combined with seamless handover. The quality of a link is permanently monitored and, if necessary, the transmission is switched to a better channel without interrupting the media stream. DECT devices have always been very power efficient but, with the arrival of ULE, the stand-by-time can be increased to up to ten years. These factors make DECT ULE technology an excellent choice for the sensors, alarms and monitoring devices used in various types of home automation.

In addition, DECT is traditionally subject to less interference than other communications technologies, due to its exclusive spectrum range in Europe and
