Digital Enhanced Cordless Telecommunications (DECT) is a standard for short range cordless mobility. DECT is originally an European standard but DECT is nowadays used world wide.
The main application for DECT is cordless telephony, but it can be used for other cordless applications as well, such as cordless office and wireless local loop.
DECT can use the frequency band ranging from 1880 - 1900 MHz in Europe. This band is divided in 10 radio channels. Each radio channel is, in periods of 10 ms, sub-divided in 24 time slots to accomodate 12 traffic channels. The uplink and the downlink are both accomodated on the same frequency. The output power of the base station is 250 mW.
In several countries outside Europe the band 1900 - 1920 MHz or 1910 - 1930 MHz is used for DECT.
DECT is also a member of the ITU IMT-2000 family of standards for the third generation (3G) for mobile communications. Within the ITU, the family member based on DECT is called IMT-FT.
ETSI published a new version of the DECT standard under the name "New Generation DECT" in august 2008. The "New Generation DECT" standard improves the support for Internet services, like Internet telephony, and the speech quality. This makes DECT ready for integrated voice and data communications, video telephony, streaming audio and other internet services.
