DECT stands for Digital Enhanced Cordless Telecommunications. It is a wireless standard that is often used for landline phones. DECT is advantageous for cordless phones because it has a long-range both indoors and outdoors and a frequency that doesn't depend on Wi-Fi. It is a versatile solution for multiple handsets requirements, and internal calls are free of charge. DECT is renowned for its audio quality and is less susceptible to inference than Bluetooth.
