Wireless Tests:
During the baseline wireless tests (with no RF
interference), the SoundStation2W was found to work better than
the Max. With the SoundStation2W, some dropouts were noted in
the audio, especially during double-talk situations. Very slight
echo was noted at the beginning of some speech segments, with a
slight bit of graininess. With the Max, some pops and clicks were
heard, along with some dropouts in the audio. Some echo was
heard during double-talk situations along with a slight amount of
graininess and distortion.
The same subjective speech evaluation was then performed with
added RF interference. In this test, the Polycom SoundStation2W
unit was much less affected by the addition of 802.11b RF inter-
ference than the ClearOne Max.
Station2W performed in a manner similar to the baseline test but
with slightly more apparent echo at the beginning of speech seg-
ments. The Max, on the other hand, produced many audible pops
and clicks, a large number of audio dropouts, many instances of
distortion, and some graininess. Under these conditions, it was
very difficult to carry on a conference call using the Max.
In the presence of 802.11g RF interference, the SoundStation2W
was found to be slightly less affected than the Max. The Sound-
Station2W performed about the same as it had with the 802.11b
interference, while the Max produced some pops and clicks, some
dropouts and echo, a small amount of graininess, and instances of
distortion. These interference-induced events affected our ability
to carry on a conference call using the Max unit.
Cellular Tests:
After performing several cell phone-to–desk
phone calls to determine baseline call quality, the Sound-
Station2W was connected to the cellular phone, allowing a con-
ference call to be conducted through the SoundStation2W. No
discernable decrease in call quality was noted when using the
SoundStation2W in this configuration.
Large Conference Room Tests:
SoundStation2W EX with add-on microphone Tests:
The SoundStation2W EX, which is designed for larger conference
rooms, was then tested. The EX is basically the SoundStation2W
unit with support for two add-on microphones. In a 24 x 30 foot
room outfitted with a 12' long table, the additional EX micro-
phones were found to perform well. It was very easy for the desk-
phone participant to hear even whispering from all participants in
the conference room, with the quality of the call being very good.
