Nokia and Taiwan Mobile demo carrier aggregation


Nokia and Taiwan Mobile have claimed a world first in New Radio (NR) carrier aggregation (CA) by combining spectrum.

Completed in standalone architecture, the carrier aggregation saw Nokia and Taiwan Mobile combine the 700MHz (n28) and 3500MHz (n78) bands.

It paves the way for Taiwan Mobile to deliver new 5G experiences to its customers with enhanced connectivity and capacity

Tom Koh, SVP and CTO, 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 utilisation of our spectrum assets and 5G networks are maximised. We are pleased with our partnership with Nokia as we continue to advance deployment and build a thriving 5G ecosystem.”

Using Taiwan Mobile's commercial 5G network, Nokia implemented its AirScale 5G SA architecture. The trial 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.

The combination of bands offered enhanced capacity and coverage supporting a range of 5G deployment scenarios, including indoor and enhanced outdoor coverage.

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.”

MediaTek Inc. supported the trial by providing equipment to verify network performance.

JS Pan, GM 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.”
