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 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.
Redefining long range coverage 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.
