Digital Enhanced Cordless Telecommunications (DECT), known as Digital European Cordless Telephone until 1995, is an ETSI standard for digital portable phones (cordless home telephones), commonly used for domestic or corporate purposes. It is recognised by the ITU as fulfilling the IMT-2000 requirements and thus qualifies as a 3G system. Within the IMT-2000 group of technologies, DECT is referred to as IMT-2000 Frequency Time (IMT-FT)
DECT was developed by ETSI but has since been adopted by many countries all over the world. The original DECT frequency band (1880 MHz–1900 MHz) is used in all countries in Europe. Outside Europe, it is used in most of Asia, Australia and South America. In the United States, the Federal Communications Commission in 2005 changed channelization and licensing costs in a nearby band (1920 MHz–1930 MHz, or 1.9 GHz), known as Unlicensed Personal Communications Services (UPCS), allowing DECT devices to be sold in the U.S. with only minimal changes. These channels are reserved exclusively for voice communication applications and therefore are less likely to experience interference from other wireless devices such as baby monitors and wireless networks.
DECT Features
Typical abilities of a domestic DECT Generic Access Profile (GAP) system include:
* Multiple handsets to one base station and one phone line socket.
This allows several cordless telephones to be placed around the house, all operating from the same telephone jack. Additional handsets usually have a battery charger station instead of a base station. The additional handsets do not require additional telephone sockets or additional transceivers
* Interference-free wireless operation to around 100 metres outdoors. Operates clearly in common congested domestic radio traffic situations. For instance, generally immune to interference from Wi-Fi networks or video senders, Bluetooth technology, baby monitors and other wireless devices.
* Ability to make internal (intercom) calls between handsets.
* An extended range between the telephone and base (allowing greater physical distance between the two devices)
* Extended battery talk-time, sometimes up to 24 hours
DECT 6.0
DECT devices made for use in the U.S. use the term DECT 6.0 to distinguish them from both DECT devices used elsewhere and U.S. cordless equipment operating in the 900 MHz, 2.4 GHz and 5.8 GHz ISM bands. It is a marketing term coined by Rick Krupka, Director of Cordless Products at Siemens, when he was pushing the FCC to accept DECT in the US and is not a spectrum band reference. The term "6.0 GHz" for DECT 6.0 phones is incorrect as they operate at 1.9 GHz, but the term DECT 1.9 might have confused customers, as they may solely interpret larger numbers as signifying a better (or later) product.
