Nokia, China Mobile [1.] and MediaTek have announced a speed record in a test of the world’s first 3 Components (3CC) Carrier Aggregation (CA) technology in Shanghai. The converged 700 MHz/2.6 GHz network reached a peak downlink speed rate of 2.94 Gbps. The trial used Nokia’s AirScale 5G baseband and MediaTek’s Dimensity 9000 5G mobile platform on China Mobile’s 5G SA network. The tests will continue, using China Mobile’s network in Shanghai.
Nokia said it is the first time the n28 (700MHz band; 30MHz) and n41 (2.6GHz band; 100+60MHz) frequency bands have been successfully combined to reach 190 MHz bandwidth (n28 + n41) with carrier aggregation technology.
CA combines frequency bands for higher data rates and increased coverage, delivering superior network capacity by maximizing the spectral efficiency of 5G networks. The combination of 5G FDD and TDD bands, supplemented by carrier aggregation, can give full play to the advantages of spectrum synergy, greatly reducing the cost of network construction while improving network coverage and user experience. The result is faster data speeds, increased coverage area, and better indoor performance.
The combination of 5G FDD and TDD bands, supplemented by carrier aggregation, augment the advantages of spectrum synergy, cutting the cost of network construction and improving network coverage and service to users.
Nokia has been a partner for over 20 years of China Mobile, which is expanding its network with the convergence of the 700 MHz and 2.6 GHz bands.
JS Pan, General Manager, Wireless Communication Technology at MediaTek, said: “Through this tripartite collaboration we have successfully demonstrated the technical advantages of DL 3CC CA using FDD+TDD. Smartphones powered by the new Dimensity 9000 flagship 5G mobile platform, and forthcoming Dimensity 5G mobile platforms, will be able to take advantage of this cutting-edge 5G connectivity feature, and MediaTek will continue to work closely with industry partners to set new milestones for 5G development.”
Ding Haiyu, Vice President of the Research Institute of China Mobile Communications Co., Ltd.), said: “China Mobile has been fully promoting the evolution and development of 5G technology. CMRI emphasizes that new technology verification provides a technical basis for the improvement of network performance and services, and forms a technical cornerstone for future network planning. China Mobile is also committed to building a 5G multi-frequency collaborative network; This 3CC CA verification can provide users with better throughput and user experience, and provide good technical foundations for new services. China Mobile is willing to work with all vendors to contribute to the 5G evolution.”
Mark Atkinson, SVP, Radio Access Networks PLM at Nokia said: “Nokia has put a strong focus on leading in 5G Carrier Aggregation. This new speed record, using commercially available hardware and software, highlights how Nokia’s pioneering approach continues to drive important innovation in the market. 5G Carrier Aggregation is a critical technology for mobile operators around the world to maximize the impact of their spectrum holdings and deliver enhanced coverage and capacity to subscribers. Nokia will keep pushing the boundaries of 5G to deliver industry-leading performance.”
