DECT Technology


DECT - Worldwide Technology for Voice and Data Applications

Since its creation in 1992, DECT (Digital Enhanced Cordless Telecommunications) technology has supported both voice and data services on any spectrum allocated to DECT,  and describes the radio interface. The key parameters determining the use of DECT are part of the ETSI Base standard. DECT, DECT 6.0 (DECT in NA/LATAM) and their successor CAT-iq, are adopted in more than 100 countries worldwide (see map). Other developments in the standard are described below. An overview of the spectrum allocation by country is available in the member section.

DECT Technology
DECT Basic Standard
The DECT base standard EN 300 175-1: published by ETSI (European Telecommunications Standards Institute) – standardizes the air interface for DECT voice and data traffic. The DECT standard has seen huge worldwide widespread adoption on radio spectrum close to that assigned in the European CEPT region. DECT provides personal telecommunication services in residential and enterprise environments. 
It is particularly targeted at the following applications:
·         Residential: narrowband voice services;
·         Enterprise: Includes PBXs and associated telephones, headsets, intercom systems, conferencing systems);
·         Wireless Sensor networks using ULE(Ultra Low Energy - a 100% DECT compatible technology standard for battery powered devices using the DECT radio spectrum. Typical applications include Home Automation Networks
·         Machine to machine or machine to man wireless communications (e.g. sensors, alarms, monitoring and metering devices);
·         DECT is also used increasingly in Program Making and Special Events use cases both indoor and outdoor, e.g. In ear monitoring for recording artists, wireless intercom for event coordination.

DECT New Generation
The underlying technical specification is called TS102527 and standardized the integration of DECT into the Broadband Home Gateway. The name given to this technology step is CAT-iq (Cordless Advanced Technology: Internet and quality). This upgrade to the base standard enabled many new SIP supplementary features and HD Voice which is compatible with the HD Voice in mobile networks. DECT Forum members can certify their products in the CAT-iq certification program.

ULE
Ultra Low Energy was standardized in 2013 in ETSI TS 103939-1 and increasingly found in wireless home networks and many other applications requiring reliable power saving connectivity. 

DECT Evolution: EN300 175-1
DECT Evolution brings some changes in the ETSI DECT standard that help increase its suitability to market spaces with stringent latency and/or reliability requirements, such as Industry 4.0 and PMSE (Program Making and Special Events)

ITU-R
DECT is part of the IMT-2000 family. DECT is called IMT-2000 FDMA/TDMA, and is defined in ITU-R Recommendation M.1457-9 (05/2010). DECT Forum and ETSI TC DECT are also a technology proponent for IMT-2020 with DECT-2020.

Worldwide Frequencies: (Please contact secretariat@dect.org to find out your country's DECT spectrum).
Europe
DECT, CAT-iq , ULE, DECT Evolution all operate on frequencies between 1880MHz -1920 MHz.
NA / LATAM
DECT, DECT-6.0, CAT-iq, ULE, DECT Evolution all operate in the USA in the UPCS band 1920-1930 MHz. The UPCS rules are found in FCC Part 15 Subpart D. 
Japan
DECT in Japan is working in the 1894 MHz to 1904 MHz band and is branded as J-DECT
