World's First Interference-Aware Technology Delivered on Mass Market Platform

BRISTOL, England, January 20 - Icera Inc., the Mobile Broadband semiconductor company, today
announced the availability of IceClear(TM), the company's new
"interference-aware" receiver technology. Using sophisticated signal
processing algorithms implemented in software, IceClear(TM) cancels the
effect of interference from other cells, delivering up to triple the previous
user data rate and cell site network efficiency. IceClear(TM) has been
shortlisted for a GSM Association 2010 Global Mobile Award in the Best Mobile
Technology Breakthrough category.

Interference-aware receiver technology has been known to
achieve substantial user throughput and cell capacity gains for some time,
but until now has been prohibitively complex and expensive to implement. The
advantage of IceClear(TM) is to deliver this technology in software at no
additional silicon cost.

IceClear(TM) provides material gains in user throughput right
across the cell site but with particularly high gains towards the cell edge.
In representative tests, where one dominant interfering cell limits user
throughput to a few hundred kilobits per second, IceClear(TM) multiplies the
throughput by a factor of up to 3.6 times.

Steve Allpress, CTO of Icera Inc., said: "IceClear(TM) is the
latest in a series of innovations that is providing continuous competitive
advantage to Icera's customers. Mobile network operators are focusing on and
differentiating themselves through the quality and consistency of their
mobile broadband services. They can now look forward to delivering
dramatically improved user data rates on their existing networks in a matter
of weeks. This means that true mobile broadband can now be a reality for
cellular users, irrespective of where in the network they happen to be."

Until now, the mobile broadband user experience has tapered
from the high headline rates achieved when the user is close to the base
station, to much lower data speeds at the cell edge. Previously, the data
throughput has been further seriously limited at the cell edge due to
interference, referred to as dominant interference power, from signals of the
same frequency and of similar strength, transmitted by adjacent cell sites.

The use of current generation equalizer and diversity
technology in mobile broadband chipsets materially improved user data rates
compared with earlier rake receiver systems, however data rates remained poor
at the cell edge in loaded networks. Hardware-based methods of cancelling the
dominant interference sources require additional complex and silicon-hungry
signal processing algorithms. For these cost and complexity reasons, no other
mainstream HSPA chipsets have delivered interference cancellation
technologies in production products to date.

Unlike any other baseband technology, Icera's Adaptive
Wireless(TM) executes the entire modem in software on a specific high
performance processor. This approach produces a unique flexibility to develop
and implement advanced algorithms, which can adapt dynamically to specific
channel conditions, in software, without the need to add any extra silicon
blocks to the chip.

IceClear(TM) is included in the latest version of Icera's
Adaptive Wireless(TM) soft modem providing a significant enhancement to
customers with what is already independently recognized as the industry's
top-performing HSPA mobile broadband technology
