Nokia can boast of another world-first as it successfully completes a carrier aggregation in a 5G standalone (SA) network environment.

The vendor partnered with Taiwan Mobile to combine spectrum in the 700MHz (n28) and 3500MHz (n78) bands in a New Radio Carrier Aggregation (NR CA) trial.

Tom Koh, SVP and CTO of the Technology Group at Taiwan Mobile, said:

“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.”

Carrier aggregation increases coverage, supports higher rates, and enables the benefits of 5G networks to be maximised by delivering enhanced network capacity.

Mark Atkinson, SVP of Radio Access Networks PLM at Nokia, commented:

“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.”

The trial used Nokia’s AirScale 5G SA architecture in Taiwan Mobile’s commercial 5G network and combined two spectrum bands, frequency division duplex (FDD) in 700MHz (n28) and time division duplex (TDD) in 3500MHz (n78). Both bands are widely used for 5G networks around the world.
