What is DECT 6.0 Technology?
DECT 6.0 (Digital Enhanced Cordless Telecommunications) represents a significant advancement in cordless phone technology, offering improved clarity, security, and range compared to older standards. AT&T leverages this technology in its phone systems to deliver a superior calling experience.
Unlike older 2.4 GHz and 5.8 GHz systems, DECT 6.0 operates on a dedicated frequency band, minimizing interference from other wireless devices like Wi-Fi routers and Bluetooth gadgets. This results in fewer dropped calls and clearer audio. Furthermore, DECT 6;0 incorporates enhanced security features, protecting your conversations from eavesdropping.
The AT&T DECT 6.0 user manual provides detailed information about this technology and how it benefits your specific phone model. You can find the manual online at www.telephones.att.com/manuals.
