Nokia (NYSE:NOK) and O₂ Telefónica Germany has aggregated sub-6 GHz spectrum frequencies in an industry-first two-component carrier uplink Carrier Aggregation trial on 5G Standalone.
Together with O2 Telefonica Germany, Nokia is the first to combine sub-6 GHz spectrum to boost uplink throughput.
Carrier Aggregation will improve the performance of 5G by delivering improved UL network usability at the cell edge with higher reliability and lower latency.
The Faster uplink speeds in Carrier Aggregation will support the metaverse era.
The trial took place at O2 Telefonica’s Innovation Cluster near Berlin and utilized O2 Telefonica’s live commercial network.
Nokia provided solutions from its AirScale portfolio including Baseband, massive MIMO, and RRH products, powered by its Reefshark chipset.
The companies used the combination of a 20 MHz carrier on the 1800 MHz band (n3) and a 70 MHz carrier on the 3.6 GHz band (n78) using Carrier Aggregation technology to achieve a peak throughput of 144 Mbps.
