Company Adapts Innovative Noise Cancelling Technology to
Wireless Handheld 
Devices


    SANTA CLARA, Calif., Dec. 7 /Xinhua-PRNewswire/ --
Quellan today 
announced the extension of its innovative Wideband noise
cancellation 
technology to mobile handsets and consumer devices. 
Successfully used in 
data center applications to improve the crosstalk, speed
and reach of 
interconnects, these smaller and lower power consumer
devices reduce noise in 
wireless handsets, laptop computers and game consoles. 
Unlike filters, these 
devices cancel wideband noise in the receivers' input
spectrum.  By dropping 
the noise floor at the receivers input, a substantial
improvement in signal-
to-noise ratio is achieved, resulting in fewer dropped
calls, continuous 
video capability and GPS location locks in high density
urban areas.

    "It's very clear that Quellan's innovative noise
cancellation 
techniques will have significant quality of service
benefits in numerous 
wireless systems such as cellular, GPS, and digital
terrestrial television 
systems," said Dermot Nolan, Director of
Telecommunications & Broadcast 
Services in London, England. "For carriers and
operators, the improvement in 
overall end-to-end link budgets if Quellan's techniques are
implemented in 
receivers may lead to significant network cost savings and
a massively 
enhanced customer experience." 

    While the technology operates in a similar fashion to
Noise Cancelling 
Headphones, Quellan's noise cancellers operate at one
million times higher 
frequency and are embodied in tiny, ultra-low power CMOS
silicon. 
 
    "Quellan's noise cancellation is an enabling
technology for adding 
wireless capability to high density, small mobile
systems," said Robert 
Dobkin, CTO of Linear Technology Corporation. "Today's
mobile systems have 
fast digital processors that step on low level wireless
signals, diminishing 
performance or even rendering mobile operation unusable.
Quellan's noise 
cancellation technology can get the signal back."

    Quellan's noise cancellers are just a few square
millimeters in size -- 
yielding tens of thousands of devices on a single silicon
wafer -- making 
them very inexpensive and embeddable in any consumer
device.

    "Noise is one of the main performance limiters for
leading consumer 
electronic products, especially within digital wireless
devices," said Bill 
Byun, Partner of Samsung Ventures America.  "Quellan
has a unique solution to 
this problem that triggered our investment."
