Digital Enhanced Cordless Telecommunications (DECT) systems now "Fit for the Internet"

ETSI Headquarters, Sophia Antipolis, France - 6 August 2008

ETSI is pleased to announce the latest Release of the DECT standard, the dominating technology for cordless residential and business applications.

The new Release is focused on two main driving forces: Internet and Quality and provides complete coverage of DECT base stations connected to the internet by means of VoIP SIP or H.323 interfaces. Without leaving behind all possibilities of base stations linked via PSTN/ISDN network, the new standard now includes support for all complex service scenarios possible with SIP and H.323 VoIP technologies.
The latest Release, dated June 2008, includes a new edition of the DECT common interface (DECT CI), EN 300 175 parts 1 to 8, a new edition of the Generic Access Profile (GAP), EN 300 444, and two New Generation DECT specifications: part 1 (TS 102 527-1) wideband speech, and the new one; TS 102 527-3 extended wideband speech services.

The standard has been enriched with a set of new wideband and super-wideband audio codecs including G.722, G.729.1 and MPEG-4 supporting high quality audio transmission up to 14 kHz and now provides the means to control audio quality with a set of "audio models" which define the acoustic performance of all DECT devices. Several models are available allowing the manufacture of DECT devices with different levels of acoustic quality. Whereas the base level is the same as existing DECT devices, the highest level may provide acoustic quality close to professional audio or High Fidelity devices.

Other improvements have been introduced in the field of packet data transmission that now extends its maximum sustainable rate to 844 bit/s with basic GFSK modulation and more than 5 Mb/s with the High Level modulation option. All audio specifications will be controllable by means of dedicated test specifications.

The development of a new Release of the DECT standard which supports the latest ‘New Generation DECT' specifications is yet another important milestone for ETSI.

ETSI Technical Committee DECT Chairman Günter Kleindl said:
"DECT is now fit for the Internet with these enhancements and the new version will be provided to the ITU to update the related IMT-Recommendations. Consequently, we will see additional growth in the market. However, despite this latest achievement there is no time to relax and work continues to advance the DECT system even further in order to support additional user requirements as provided by the DECT Forum and the new interface requirements as defined by the ITU.'

Angel Bóveda, a strategic consultant specialized in wireless technologies and leader of the ETSI Special Task Force (STF) 338 said:
"The new update of the standard has been focused on Telephony over Internet and that is now the primary target scenario, providing complete support for VoIP SIP and H.323 applications. The inclusion of high quality 7 kHz and 14 kHz telephony will raise the telephone experience to a further level."

New Generation DECT is sure to be another best-seller for the Telecom industry and a great success for ETSI and the new Release means the DECT standard is set to remain the dominating technology for cordless residential and business applications for many years. Indeed, the combination of low power consumption, range, and power within the DECT standard has not been reached by any other technology. (The new standard is back compatible with all existing DECT devices).
