Nokia achieves first 5G carrier aggregation call in
standalone architecture with Taiwan Mobile
- Successful trial aggregates spectrum in the 700MHz (n28) and
3500MHz (n78) for the first time to deliver enhanced connectivity
and increased coverage
- Trial supports Taiwan Mobile’s vision to deliver market-leading
5G services to customers
3 August 2021
Espoo, Finland – Nokia and
Taiwan Mobile (TWM)
today announced
that it has achieved the
world’s first New Radio
Carrier Aggregation (NR CA) by
combining spectrum in the 700MHz (n28) and 3500MHz (n78) bands.
The trial, which took
place in a 5G
standalone (SA) network
environment, paves the
way for TWM to deliver market-leading 5G experiences to
its customers with
enhanced connectivity and
capacity. Carrier Aggregation
combines frequency bands for higher rates and increased coverage,
delivering superior network
capacity and maximizing the spectral efficiency of 5G
networks.
The successful trial was performed with Nokia’s AirScale 5G SA
architecture in TWM’s commercial 5G network and combined two
spectrum bands, frequency division duplex (FDD) in 700MHz (n28) and
time division duplex (TDD) in 3500MHz (n78), which are widely
adopted in 5G networks worldwide. FDD is a lower frequency band
that provides wide coverage area improving cell edge performance;
TDD has a higher bandwidth and capacity. The combination of these
spectrum bands offers enhanced capacity and coverage supporting a
range of 5G deployment scenarios, including indoor and enhanced
outdoor coverage. MediaTek Inc. supported the trial by providing
equipment to verify network performance.
Nokia is TWM’s sole 5G equipment supplier covering 5G RAN, 5G
Core and 5G IMS including its latest AirScale Radio Access
products. Nokia is a long-standing partner of TWM and is supporting
the company in its efforts to execute its ‘Super 5G strategy’ which
is focused on sustainability and digital transformation.
Tom Koh, Senior Vice President
and Chief Technology
Officer, Technology Group, Taiwan
Mobile, commented: “This trial is an
important milestone as we execute our 5G strategy and deliver
best-in-class 5G services to our subscribers. Combining SA with NR
CA, our 5G user experience is raised to the next level while the
utilization of our spectrum assets and 5G networks are maximized.
We are pleased with our partnership with Nokia as we continue to
advance deployment and build a thriving 5G ecosystem.”
Mark Atkinson, SVP, Radio Access Networks PLM at Nokia,
said: “We are delighted to have completed this successful
trial with our trusted partner, Taiwan Mobile. Aggregating spectrum
is an efficient way to enable enhanced coverage and capacity. This
successful trial highlights how mobile operators with similar
spectrum allocation can achieve similar results.”
JS Pan, General Manager of Wireless System Design and
Partnership at MediaTek, said: “MediaTek continues to
collaborate with ecosystem partners to accelerate the development
of global 5G markets. Our joint effort with Nokia and Taiwan Mobile
has led to this breakthrough in commercial 5G Standalone network
capabilities that will facilitate better services.”
