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
independent laboratory has confirmed that AT&T DECT 6.0 products perform up to 45% better
in range competitions. Now calls can be taken in the basement, backyard and garage with
exceptional sound quality.
Telephone operating range
This cordless telephone operates within the maximum power allowed by the Federal
Communications Commission (FCC). Even so, the deskset can communicate over only a certain
distance — which can vary with the locations of the deskset, the weather, and the construction of
your building.
