Icera Launches IceClear(TM) Technology to Triple HSPA User Data Rates & Cell Site Capacity
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
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.
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
