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 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.
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.
