5.8 GHz digital spread spectrum frequency hopping technology
This technology digitally transmits your voice across multiple channels in both
the 5.8GHz and 2.4GHz frequencies to provide enhanced range, ultimate sound
clarity and advanced privacy against eavesdropping on your calls, 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 base can
communicate over only a certain distance — which can vary with the locations
of the base and handset, the weather, and the construction of your home or
office.
