Wireless Technology

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.
Digital Spread Spectrum technology
breaks the voice stream into small
fragments and spreads them over a
wide range of frequencies for trans-
mission to a receiver. Only the re-
ceiver that is uniquely registered to the

Security

The SoundStation2W™ is a highly secure voice
communications solution. There are five factors that
contribute to the robust security:
1. Unique pairing between console
and base station.
2. WDCT and DECT digital
spread spectrum technology
provides secure transmission.
3. The frequency hopping WDCT
and DECT implementation
makes it even more difficult for
voice signal to be intercepted.

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-
ments Digital Spread Spectrum using
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.
