DECT 6.0 digital technology

Digitally Enhanced Cordless Telecommunications (DECT) 6.0 is a new
frequency band that transmits your voice across multiple channels. This
technology provides superior quality of voice and sound, high protection
against wiretapping and better range than 2.4GHz and 5.8GHz phone
systems, while not interfering with wireless routers.

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.
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.
