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, this handset
and telephone base can communicate over only a certain distance
— which can vary with the locations of the telephone base and handset,
the weather, and the construction of your home or office.
Extended range and clarity
This telephone base comes with an antenna which gives much better
clarity and covers a longer range than before.
