Nokia and MediaTek achieve 3.2 Gbps with FDD/TDD aggregation

Nokia and MediaTek achieved 3.2Gbps peak downlink throughput by aggregating 5G Standalone (5G SA) spectrum using 3 Components Carrier (3CC) aggregation, effectively combining 210MHz of FDD and TDD spectrum.

Nokia supplied its latest AirScale equipment including its AirScale 5G SA architecture powered by its ReefShark System-on-Chip (SoC) technology as well as its cloud-native 5G core. MediaTek provided its new M80 5G modem which combines mmWave and sub-6 GHz capabilities onto a  single chip as well as the user equipment testing platform.


Frequency division duplex (FDD) in 600MHz (n71) is a lower frequency band that provides a wide coverage area, improving cell edge performance. Time-division duplex (TDD) in 2600MHz (n41) has higher bandwidth and capacity. The combination of these spectrum bands supports a range of 5G deployment scenarios including indoor as well enhanced outdoor coverage. The high-band sub-6Ghz spectrum bands support high-capacity and extreme mobile broadband capabilities.

JS Pan, General Manager, Wireless Communication System, and Partnerships at MediaTek, said: “This test demonstrates the importance of carrier aggregation in enabling mobile operators around the world to deliver best-in-class speed and capacity to their subscribers. The combination of Nokia’s AirScale portfolio and our technology boosts the possibilities of spectrum assets and 5G networks. We look forward to continuing to partner with Nokia to advance the 5G ecosystem.”
