Short for Digital Enhanced Cordless Telecommunications DECT is a digital wireless technology that originated in Europe, but is now used worldwide. DECT is a radio technology for voice data applications (such as cordless telephones, wireless offices and even wireless telephone lines to the home). DECT uses time division multiple access (TDMA) to transmit radio signals to phones and is best-suited to smaller areas with a large number of users. It has been designed and specified to work with many other types of network, such as the PSTN, ISDN, GSM and others.
