By combining spectrum in the 700 MHz (Band n28) and 3500 MHz (Band n78) bands, Nokia has created a 5G first, reports EENews Europe. The merger of the two frequency bands allows for higher rates and increased coverage, claims Nokia, boosting network capacity and making the most of the spectral efficiency of 5G network systems.
“This trial is an important milestone as we execute our 5G strategy and deliver best-in-class 5G services to our subscribers,” stated Tom Koh, Senior Vice President and Chief Technology Officer, Technology Group, Taiwan Mobile. Taiwan Mobile was Nokia’s partner in the project and operates its network with Nokia as its exclusive equipment supplier. Nokia components support its 5G RAN, 5G Core and 5G IMS functions, including its AirScale Radio Access products.
“Combining [the bands], our 5G user experience is raised to the next level while the utilization of our spectrum assets and 5G networks are maximized,” Koh told EENews Europe. “We are pleased with our partnership with Nokia as we continue to advance deployment and build a thriving 5G ecosystem.”
The trial took place in a 5G standalone test using Nokia’s AirScale 5G SA architecture. Taiwan Mobile’s commercial 5G network provided support with Mediatek 5G equipment. The trial combined frequency division duplex (FDD) transmissions at 700 MHz and time division duplex (TDD) multiplexing at 3500 MHz.
Mark Atkinson, SVP, Radio Access Networks PLM at Nokia, noted, “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.”
