Nokia, China Mobile (CMCC) and MediaTek have achieved record speeds of 3 Gbps in 5G autonomous (5G SA) in the world's first test of three-component carrier aggregation technology.
To date, almost all early 5G deployments have been based on non-standalone 5G (NSA 5G), which uses new radio technologies but still relies on the underlying 4G core.
SA 5G uses a new cloud-based virtual core that allows data to be processed closer to the point of collection and enables features such as network cutoff. This enables guaranteed speeds, increased reliability, and ultra-low latency.

Meanwhile, carrier aggregation merges separate bands of spectrum to exploit the advantages of each. For example, marrying the coverage and indoor propagation rates of low-band frequencies with the high capacity and data rates of mid- and high-band airwaves.
This capability will not only improve speeds and coverage, but will allow operators to do so using their existing assets, reducing the cost of network deployment.
Carrier aggregation has been used on 4G and 5G networks, offering speeds in excess of the 3 Gbps reported by Nokia and its partners. However, it is the fastest yet using only 5G SA technology, and it offers an indication of what might be possible in a real-world environment.
For this test, the partners combined 30MHz of 700MHz and 100+160MHz of 2,6GHz to achieve record transmission speeds, demonstrating the potential of 5G technology to deliver even higher performance.
The record was achieved in Shanghai using Nokia radio equipment, China Mobile's network and MediaTek's 9000 5G mobile platform.
"Nokia has focused on leadership in 5G carrier aggregation. This new speed record, using off-the-shelf hardware and software, shows how Nokia's pioneering approach continues to drive significant innovations in the market," said Mark Atkinson, director of Nokia Radio Access Networks PLM. .
“5G carrier aggregation is a critical technology for mobile operators around the world to maximize the impact of their spectrum holdings and deliver better coverage and capacity to subscribers. Nokia will continue to push the boundaries of 5G to deliver cutting-edge performance. »
“China Mobile is committed to building a 5G multi-frequency collaborative network; This verification can bring users better performance and user experience, and provide a good technical foundation for new services,” added Ding Haiyi, vice president of the China Mobile Research Institute.
