DECT (Digital Enhanced Cordless Telecommunications) is a digital wireless telephone standard developed in 1988 by ETSI to provide secure, high-quality transmission for cordless phones. It uses TDMA to transmit radio signals between DECT phones and their base stations. DECT has applications for homes, businesses, and industry and provides mobility and seamless handover between multiple base stations. While originally developed for Europe, DECT is now used globally and competes with technologies like Bluetooth for short-range wireless applications. The future of DECT includes expanding its use in security systems, data transmission over the internet, and new country adoption.
