A1 Telekom Austria and Nokia Achieve 2 Gbps on 5G With 3CC

Nokia and A1 Austria announced that they have successfully demonstrated 3 Component Carrier Aggregation (3CC CA) on a 5G Standalone (SA) trial network in Austria, reaching data rates of 2 Gbps. Carrier Aggregation (CA) enables mobile operators to achieve higher throughputs and improved coverage. This will let A1 provide its subscribers with a superior 5G experience.

Carrier Aggregation on 5G

Over the 5G network of A1 Austria, the trial used Nokia’s AirScale 5G baseband, a 5G smartphone, and commercial 5G Customer Premise Equipment (CPE). It utilized carrier aggregation technology to effectively combine two mid-band carriers in the 3.5 GHz TDD band (n78) and one capacity carrier in the 2100 MHz FDD band (n1) for a total bandwidth of 160 MHz. As a result, the trial’s highest downlink data rate was 2 Gbps.

Carrier Aggregation Specification

Component Carriers: Two 3.5 GHz TDD (n78) Carriers + One 2100 MHz FDD (n1) carrier
Total Bandwidth: 160 MHz
Result: 2 Gbps Data Rates

Mid Bands Provide Coverage and Capacity

Operators are relying on the Sub-6 GHz spectrum for 5G. Low-frequency bands provide the best coverage, and High-frequency bands enable higher throughputs, while mid-bands – provide a good combination of both (coverage and capacity).

To recollect, Airtel followed a similar spectrum strategy for its 5G NSA, as the telco has a massive mid-band spectrum.

Commenting on the 3CC verification, Alexander Stock, CTO, A1 Austria, said: “This trial is an important milestone as we continue to deliver on our strategy of bringing best-in-class 5G services to our subscribers. Maximizing our spectrum assets will enhance coverage, capacity, and performance and we are pleased to continue to work with our long-standing partner, Nokia to realize the full potential of 5G technology.”
