DECT 6.0 digital technology

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
2.4 GHz and 5.8 GHz 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 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.
