DECT

DECT (Digital Enhanced Cordless Telecommunications) is a flexible digital radio access standard for cordless communications in residential, corporate, and public environments. It is supported and promoted by the DECT forum. This forum has representatives in all the major geographical regions around the world. DECT provides for voice and multimedia traffic, and contains many forward-looking technical features that allow DECT-based cordless systems to play a central role in important new communications developments, such as Internet access and interworking with other fixed and wireless services like ISDN and Global System for Mobile Communications (GSM). The DECT standard makes use of several advanced digital radio techniques to achieve efficient use of the radio spectrum; it delivers high speech quality and security with low risk of radio interference and low power technology.

TDMA (Time Division Multiple Access) radio access, with its low radio interference characteristics, provides high system capacity for users of in-home networks. ADPCM (Adaptive Differential Pulse Code Modulation) speech encoding ensures a DECT cordless phone very high speech quality, comparable to wireline telephony. DCS/DCA (Dynamic Channel Selection/Allocation) is a unique DECT capability that guarantees the use of the best radio channels available. This happens when a cordless phone is in stand-by mode, and throughout a call. This capability ensures that DECT can coexist with other DECT applications and with other systems in the same frequency, with high-quality, robust, and secure communications for end users. Other features of the DECT standard include encryption for maximum call security and optimized radio transmission for maximum battery life.
