Ericsson triples HSPA uplink capacity

* 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
