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.

Simulated full-duplex handset speakerphone

The simulated full-duplex speakerphone on your handset allows both ends
of a call to speak and be heard at the same time. Optimal performance is
subject to external factors and individual usage.
