Digital Enhanced Cordless Telecommunications technology lets you move freely around your home with long range, reduced interference and amazingly clear sound. Digital Enhanced Cordless Telecommunications (DECT) phones operate at the 1.9 GHz frequency. This frequency is reserved for cordless phone usage only which offers virtually interference free usage. The Wi-Fi friendly DECT technology was developed with areas that could have a large number of users and it easily integrates into homes with Wi-Fi services and other wireless devices. Key advantages are that the 1.9 GHz frequency is not used by other wireless technologies, battery life is usually improved by 30% over 5.8ghz and also DECT  typically provides greater range than cordless phones that operate at other frequencies.
