DECT 6.0 digital technology
This technology digitally transmits your voice across multiple channels using
the newly available DECT 6.0 frequency band. This technology provides superior
quality of voice and sound, high protection against wiretapping and better
range than the 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 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.
