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 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.
