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.
Redefining long range coverage and clarity
This telephone base comes with an antenna which gives much better clarity and covers
a longr 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.
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.
