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
against similarly equipped phones of the leading competition. 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.

HD audio

HD audio improves sound quality by expanding and rebuilding frequencies
that are lost with traditional phone calls. There is no additional telephone
service requirement to use HD audio. It is designed to work with standard
telephone service. Your system will automatically enhance all received sound
with HD audio.
