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.
