About DECT Technology: Advanced DECT 6.0 technology, or Digital Enhanced Cordless Telecommunications, operates on the newly released 1.9 GHz frequency band that was recently allocated to support cordless telephony. Uniden DECT 6.0 incorporates unique "listen before transmit" technology that avoids interference with many household products, such as baby monitors, microwaves and WiFi (which operate on frequencies like 2.4 GHz). As a result, DECT phones offer consumers enhanced voice clarity and crystal clear digital sound quality. DECT 6.0 technology also offers higher security and voice protection, as well as a longer battery and battery standby life than existing 2.4 GHZ or 5.8 GHz phones.
