DECT 6.0 digital technology
Digital 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
2.4 GHz and 5.8 GHz phone systems, while not interfering with wireless routers.
Operating range
This Conference Speakerphone with Wireless Mics operates within the maximum
power allowed by the Federal Communications Commission (FCC). Even so, the
wireless mics and base unit can communicate over a certain distance — which can
vary with the locations of the base unit and wireless mics, the weather, and the
construction of your home or office.
Full-duplex speakerphones
The full-duplex speakerphones on your base unit and wireless mics allow both ends
of a call to speak and be heard at the same time. Optimal performance is subject to
external factors and individual usage.
