Icera Soft Modem Selected for Vodafone 14.4 HSPA USB Stick
Broadband semiconductor company, today announced that its Livanto(R) chipset
and Adaptive Wireless(TM) technology is at the heart of Vodafone’s latest
mobile broadband USB stick, the Vodafone K3805-Z.
Offering a high speed mobile broadband connection with theoretical peak
downlink rates of up to 14.4 Mbps HSPA in optimal conditions, the Vodafone
K3805-Z is the world’s first USB modem to incorporate Icera’s IceClear(TM)
interference-aware technology. IceClear(TM) uses sophisticated signal
processing algorithms implemented in software to cancel the effect of
interference from other cells, potentially delivering up to triple the
previous average connection speeds for Vodafone customers in weaker signal
areas and improving network efficiency and reliability.
Group, commented: “Our aim is to provide our customers with a best-in-class
experience of services through Vodafone’s high-speed mobile broadband network
and we track and selectively collaborate on innovative technologies with
cellular chipset partners to achieve this. Icera’s unique soft modem
technology, including the latest IceClear(TM) interference aware receiver,
shows how this directly benefits our customers’ experience.”
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), to
manufacturers, operators and customers, is to deliver this technology in
software at no additional silicon cost. Users will notice the difference for
sure and we’re thrilled to have Vodafone as a launch operator.”
Vodafone’s K3805-Z will be available from Vodafone across
selected African countries.
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, IceClear(TM) increases the throughput by a factor of up
to 3.6 times.
Until now, the mobile broadband user experience has tapered from the high
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
limited at the cell edge due to interference from signals transmitted by
adjacent cell sites.
The use of traditional 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.
