Taiwan Mobile (TWM) and Nokia claim to have achieved the world’s first New Radio Carrier Aggregation (NR CA) call by combining spectrum in the 700MHz (n28) and 3.5GHz (n78) bands. In a press release regarding the development, the Finnish vendor noted that the trial took place in a 5G standalone (SA) network environment and was performed using its AirScale 5G SA architecture in TWM’s commercial 5G network; MediaTek supported the trial by providing equipment to verify network performance. According to Nokia, the combination of the 700MHz and 3.5GHz spectrum bands offers enhanced capacity and coverage supporting a range of 5G deployment scenarios, including indoor and enhanced outdoor coverage.
Commenting, Tom Koh, Senior Vice President and Chief Technology Officer, Technology Group, 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 utilization 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.’
