Viettel has become the first network operator in Vietnam to successfully integrate 11 bands on the actual 5G SA network platform. The outstanding point of this solution lies in the advanced band integration technology NR-DC (New Radio Dual Connectivity) and CA (Carrier Aggregation).
Instead of transmitting data on a single "lane" like the usual 5G network, this technology allows "concurrent combination of multiple lanes" for data to run in parallel, helping to maximize total bandwidth.
Viettel has successfully combined 3 bands belonging to the C-band (3500MHz) broadband band and 8 bands belonging to the high-speed mmWave (26GHz) band to create a broadband transmission infrastructure. This is an achievement that no network operator in Southeast Asia has ever achieved, and is also the only way to break through mobile speed that no other solution can replace.
At the same time, Viettel has pioneered the application of border data processing solutions to help user data be processed instantly on the spot instead of having to go around, minimizing latency and package dropping, paving the way for a maximum speed of over 10Gbps.
The 5G Advanced network is being tested by a team of engineers from Viettel Network Corporation, Ericsson and MediaTek in coordination on Viettel's existing 5G commercial infrastructure, combined with Ericsson's multiband 5G gNodeB base transceiver and MediaTek's M90 chipset. This breakthrough success is clear evidence of Viettel's team's comprehensive control of the 5G network system, from core networks, transmission, radio to end-to-end devices.
Notably, the 5G SA core network system used in the test is not an isolated laboratory environment, but the actual commercially operating infrastructure nationwide of Viettel.
The result of 10 Gbps is an inevitable consequence, creating a solid premise for the formation of a "super high-bandwidth digital infrastructure" serving national digital transformation. This platform allows instant processing of huge volumes of data serving AI and Big Data in real time, while completely eliminating lag to bring smooth virtual reality (AR/VR/XR) experiences in remote healthcare and digital education.
In particular, this is also the basis for providing super-stable connections for millions of smart devices, creating strong momentum to promote the development of smart factories, automation systems and high-tech industrial production.
Speaking about this milestone, Mr. Hoang Binh Son - Deputy General Director of Viettel Networks - emphasized: "Viettel always maintains the mindset of being self-sufficient in the latest technologies to accompany the development speed of the world. The test results reaching 10 Gbps are the basis for Viettel to continue deploying advanced solutions, building super high-bandwidth digital infrastructure. We are ready to make telecommunications a driving force to promote automation and strong digital economy development in Vietnam".
Dr. Rita Mokbel - President and CEO of Ericsson Vietnam - shared: "We are proud to cooperate with Viettel to establish this impressive result. The 10 Gbps speed affirms the superior strength of 5G technology in optimizing network performance and opening up new applications (use cases). Ericsson is committed to continuing to accompany Viettel in building a secure, scalable network infrastructure, contributing to promoting digital transformation and socio-economic development of Vietnam.
The success of the test reaching a speed of 10 Gbps shows the breakthrough potential of 5G features such as NRDC, Carrier Aggregation and advanced radio technologies in improving data transmission speeds".
Dr. HC Hwang - General Director in charge of Wireless Communication Systems and Partnerships at MediaTek - commented: "Overcoming the 10 Gbps mark is a turning point for 5G Advanced. The result of 10 Gbps on the MediaTek M90 modem platform continues to affirm the capacity of 5G Advanced and the new opportunities that this technology opens up.
This achievement further strengthens our belief in the value that 5G Advanced brings to practical deployment networks and demonstrates Viettel's ability to integrate advanced technologies throughout the network ecosystem".
This event continues to affirm Viettel's leading position in the digital infrastructure race. By the end of 2025, with a scale of 30,000 5G stations, Viettel has covered 90% of the outdoor area nationwide. Stepping into 2026, the network operator plans to deploy about 20,000 new 5G stations, increasing the total number of accumulated stations to a huge scale to aim for coverage reaching 97% of the population.
Continuously pioneering and being self-sufficient in the latest telecommunications technologies is Viettel's commitment to action in bringing outstanding value to the people and creating a new growth space for the Vietnamese business community.
