About Digital Enhanced Cordless Telecommunications operates on the newly released 1.9 GHz frequency band that was recently allocated to support cordless telephony. Uniden incorporates unique "listen before transmit" technology that avoids interference with many household products, such as baby monitors, microwaves and Wi-Fi (which operate on frequencies like 2.4 GHz). As a result, DECT phones offer consumers enhanced voice clarity and crystal clear digital sound quality.
