SoundStation2W™ User Guide - 10
SoundStation2W™ comes in two
different formats. The product uses
either 2.4 GHz WDCT (Worldwide
Digital Cordless Telecommunications)
or 1.9 GHz DECT (Digital Enhanced
Cordless Telecommunications) stan-
dard technology. WDCT is widely
used in North America, South Ameri-
ca, and China, while DECT is used in
Europe, parts of Asia, and Australia.
WDCT and DECT are Digital Spread
Spectrum protocols which are reliable,
secure, and support excellent voice
quality and a wide range of dialing
features. Digital Spread Spectrum has
been used by the military for many
years because there is a low probabil-
ity of signal interception and interfer-
ence.

breaks the voice stream into small

transmitter will be able to reassemble
the signal to deliver the voice stream.
The SoundStation2W™ console and
base station act as both transmitters
and receivers. The console will only
reassemble the signal sent from its
matching base station and vice versa.
Accordingly, the console will operate
within 150 feet of the paired base sta-
tion. The one-to-one pairing of con-
sole and base station ensures secure
voice signal transmission.

The SoundStation2W™ imple-

frequency hopping encoding. Fre-
quency hopping transmits the audio
signal fragments over rapidly switch-
ing frequencies in the 2.4 GHz and
1.9 GHz bands. Frequency hopping
enables the SoundStation2W™ to
automatically detect and avoid sources
of potential interference such as other
SoundStation2W™ phones or 802.11x
WLAN clients.
