DECT 6.0 digital technology
The AT&T DECT 6.0 products offer unsurpassed range performance and sound clarity. This is
achieved through a unique antenna design and advances in noise-filtering technology. An

range competitions. Now calls can be taken in the basement, backyard and garage with
exceptional sound quality.
