DECT or Digital Enhanced Cordless Telecommunications (formerly known as Digital European Cordless Telephone) is a standard for digital phones (cordless home digital telephones), commonly used for domestic or corporate purposes. DECT can also be used for high speed wireless broadband data transfers. DECT is recognized worldwide as being the future in digital phones with 3G capabilities.
DECT was developed by European Telecommunications Standards Institute 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 within Europe for digital telephones and other digital communication devices such as answerphones and fax machines.
The DECT standard fully specifies a means for a portable unit such as a cordless telephone to access a fixed telecoms network via radio, but unlike the GSM phone standards does not specify any internal aspects of the fixed network itself. Connectivity to the fixed network is done mainly through a single digital base station or "Radio Fixed Part" to terminate the internal digital radio link, and a gateway to connect calls to the fixed
DECT network. In most cases the base station connection is to the standard public switched telephone network or telephone jack point, although connectivity with newer technologies such as Voice over IP has become available by connecting to the internet through a PC or similar compatible device. There are also other devices such as some baby monitors with DECT capabilities, the difference in these devices is that there is no gateway or network functionality unlike the digital phones..
The DECT standard of communication was originally developed for the significant areas:
- Standard domestic cordless digital phones, using a single base station to connect one or more handsets to the public telecoms network via a single standard telephone jack point,
- Commercial enterprise premises cordless PABXs and wireless LAN networks, using many base stations for a wider coverage. Calls continue as users move between different coverage cells, through a mechanism called digital call handover.
- Overall public access, using large numbers of powerful base stations to provide a building or area with access to a public network via a cordless digital telephone.
