Polycom SoundStation 2W - Wireless Technology and Security

SoundStation2W™ User Guide - 10
SoundStation2W™ uses 2.4 GHz
WDCT (Worldwide Digital Cord-
less Telecommunications) standard
technology. WDCT is a widely used
wireless technology in North Amer-
ica. It is a Digital Spread Spectrum
protocol which is reliable, secure, and
supports 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 probability of signal intercep-
tion and interference.
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
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™ implements
Digital Spread Spectrum using fre-
quency hopping encoding. Frequency
hopping transmits the audio signal
fragments over rapidly switching
frequencies of more than 75 channels
in the 2.4 GHz band. Frequency hop-
ping enables the SoundStation2W™ to
automatically detect and avoid sources
of potential interference such as other
SoundStation2W™ phones or 802.11x
WLAN clients.
Wireless Technology
Security
The SoundStation2W™ is a highly secure voice
communications solution. There are ve factors that
contribute to the robust security:
1. Unique pairing between console
and base station.
2. WDCT digital spread spectrum
technology provides secure
transmission.
3. The frequency hopping WDCT
implementation makes it even
more difcult for voice signal
to be intercepted.
4. 64 bit voice encryption between
the base station and console.
This adds yet another layer of
security in order to provide
utmost condence in the
SoundStation2W™ solution.
5. Aux Out recording is controlled
from the console user interface.
