LTE Carrier Aggregation (CA) of licensed and
unlicensed bands on mobile network and devices enables smartphone
users to maintain their LTE connection while getting a speed boost
from unlicensed 5GHz spectrum
-
Successful over-the-air testing between Ericsson
RBS 6402 small cells and a Qualcomm®
Snapdragon(TM) X12 LTE
modem of LTE CA with unlicensed spectrum conducted on Vodafone's
commercial network in the Netherlands
-
Network testing further validates fair
co-existence of LTE in 5 GHz unlicensed band
Ericsson (NASDAQ:ERIC), with Vodafone and Qualcomm
Technologies, Inc., a subsidiary of Qualcomm Incorporated, today
conducted world's first live testing of advanced LTE Carrier
Aggregation (CA) of LTE in licensed and unlicensed bands on a
commercial mobile network. The trial uses the Ericsson RBS
6402 indoor small cell, which supports LTE CA between licensed and
unlicensed bands on Vodafone's commercial network, connected to a
LTE unlicensed band capable test device developed by Qualcomm
Technologies, Inc.
Matthias Sauder, chief network officer, Vodafone
Netherlands: "Our intent in deploying small cells is always
to deliver the best customer experience, and we see the potential
for LTE aggregation with unlicensed bands on small cells as one way
to make that customer experience even better. We are already
using Ericsson's RBS 6402 indoor picocell in our own shops in the
Netherlands, so it's great to see that it will also support
advanced LTE CA capabilities with unlicensed spectrum on our
network."
The Vodafone LTE trials with unlicensed spectrum
are being conducted over Vodafone's network in the
Netherlands. The latest over the air results were achieved by
aggregating 20 MHz of Vodafone spectrum in Band 3 (1800 MHz) with
20 MHz of the unlicensed 5 GHz band U-NII-1 band. The testing
validated LTE performance in the unlicensed band and fair
co-existence with other technologies like Wi-Fi within the
unlicensed 5 GHz band. The Ericsson RBS 6402 Indoor Picocell
includes a 5GHz LTE enabled radio in addition to multiple LTE radio
variants and optional 2.4 GHz Wi-Fi module - all in a sleek,
compact package with a tablet-sized footprint. The user
equipment utilized in this trial is a test device powered by the
Qualcomm®
Snapdragon(TM) X12 LTE
modem. The Snapdragon X12 LTE modem is a product of Qualcomm
Technologies.
Valter D'Avino, Head of Ericsson's Region Western
and Central Europe, says: "Vodafone has taken a leadership position
in small cells and our LTE trials on unlicensed spectrum with them,
together with Qualcomm Technologies, really underscore their
continued commitment to improving the performance of indoor
networks to ensure better app coverage for their customers.
The unlicensed 5 GHz band is a shared resource and, as we have
seen, it can be aggregated with LTE bands to provide a speed boost
for users to improve app coverage, when spectrum is available - of
course, the user also maintains their connection to Vodafone's
highly reliable LTE network, so they have a great connection no
matter what."
"Users in Europe and the rest of the world demand
better, faster and seamless connectivity," said Serge Willenegger,
vice president, product management at Qualcomm Technologies, Inc.
"The aggregation of licensed and unlicensed bands in 4G and future
5G networks is critical to achieve this goal, and we're pleased to
collaborate with Ericsson and Vodafone to test the support of such
capabilities in our Snapdragon processors and modems."
LTE CA with an unlicensed band enables operators
to combine the reliability of LTE licensed spectrum with
incremental downlink throughput improvements provided by the
unlicensed band. The functionality includes mechanisms for
sharing the unlicensed spectrum with other unlicensed 5 GHz users,
like Wi-Fi. This allows operators to leverage unlicensed 5
GHz spectrum for improved peak rates and capacity. LTE CA
with the 5GHz unlicensed band is a feature of Ericsson Networks
Software 16A, available this year.
