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."
