Ericsson triples HSPA uplink capacity

STOCKHOLM, SWEDEN — (Marketwire) — 02/22/12 —

* Uplink speed increasingly important as social media services and cloud
solutions drive data upload stream

* Unique combination of technologies triples HSPA uplink capacity,
greatly
improving user experience for content uploading

* No need to upgrade cell phones or consumer devices. Achieved by
combining
Ericsson-s leading commercial Interference Suppression software with
4-antenna radio base stations

Ericsson (NASDAQ: ERIC) has developed a unique solution that triples uplink
capacity in HSPA networks. This allows operators with a large number of end
users to offer high uplink data speeds.

HSPA is a key means of delivering high-speed, high-capacity mobile
broadband,
allowing operators to cost-effectively meet user demand for advanced
internet
services — anywhere, anytime. However, as the number of smartphones
connected to
a network increases and usage of heavy data-generating applications surges,
uplink capacity is becoming more and more important. This is the next
important
step to meet global smartphone service demands.

On January 25, 2012, Ericsson demonstrated that over-the-air uplink
throughput
for simultaneously active devices in a cell was increased from around 4Mbps
to
more than 12Mbps.The demonstrated capacity is an unprecedented figure for a
5
MHz WCDMA carrier.

This was made possible by combining Ericsson-s commercially available
receiver
technology, Ericsson Interference Suppression, with 4-antenna radio base
stations. There is no need to upgrade cell phones or consumer devices in
order
to achieve this gain.

Interference Suppression is the industry-leading base station receiver
technology for WCDMA/HSPA that can vastly improve uplink speeds by
increasing
the network capacity. This is done by using advanced software algorithms in
the
base station that greatly reduce the negative effects of uplink
interference
that is today the bottleneck in many HSPA networks.

The gains were further enhanced by the use of base stations configured with
four
antennas per cell. This combination delivers a leap in end user experience
and
uplink capacity.

Improving uplink capacity with these technologies offers operators an
elegant
way to further serve a greater number of customers, who increasingly choose
to
upload information from mobile devices to cloud services for example
sharing
photo over social networks

Nils Viklund, Director WCDMA RAN at Ericsson, says: “We have proven that
Ericsson-s unique Interference Suppression is a giant leap forward and it
will
be the new reference for WCDMA uplink performance for years to come. This
can
even be further enhanced by combining it with multi-receive antenna
technologies. Because these technologies work with existing devices,
operators
that implement them will instantly benefit from the attractive gain.”

In all parts of the world, people are adopting more advanced mobile devices
that
enable connectivity anywhere, anytime. This trend is moving us toward a
society
where places, people and devices are constantly connected – a Networked
Society.
As Ericsson-s latest Traffic and Market Data report revealed, mobile
broadband
subscriptions increased by 60 percent year-on-year in 2011, and are
expected to
number almost 5 billion in 2016.

Ericsson is committed to helping operators not only cope with increasing
amounts
of data traffic, but also to realize the opportunities that come with it.
