Specifications published on low power consumption radio technology
ETSI has published the first Technical Specification (TS 102 939-1) on DECT ULE (Ultra Low Energy), which is intended for home automation and other M2M applications.
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 Digital Enhanced Cordless Telecommunications (DECT) standard, which was developed by ETSI. The main characteristics of DECT ULE are ultra low power consumption and wider coverage than competing technologies.
DECT ULE is an ideal radio communications technology to support M2M in the home. 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. ULE allows the stand-by-time to be increased to up to ten years, which make it ideal for sensors, alarms and monitoring devices used in various types of home automation.
The DECT base standard (EN 300 175 series) has also been updated to include the necessary new protocol elements and procedures for DECT ULE, and the revised version is expected to be published early in 2014.
