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. 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. 
Extended range and clarity
This telephone base comes with an antenna which gives much better clarity 
and covers a longer range than before.
