The Ministry of Science and Technology recently issued Circular No. 02/2025/TT-BKHCN, detailing the allocation of radio frequency channels for the E-band (71-76 GHz and 81-86 GHz). Effective May 15, 2025, this circular plays a crucial role in accelerating the development of 5G networks in Vietnam.
Paving the way for high-speed data transmission for Vietnam's 5G infrastructure – 1
The Urgent Need for Upgrading 5G Transmission Infrastructure
The commercial launch of 5G networks in April 2024 necessitates urgent upgrades to transmission infrastructure. 5G’s ability to connect millions of devices simultaneously and deliver superior speeds demands transmission lines capable of immense bandwidth, up to 10 Gbps, and channel widths reaching 2000 MHz, especially for V-band links connecting base stations.
However, existing V-band frequencies below 30 GHz only allow maximum transmission capacity of around 2 Gbps. While the V-band (57-66 GHz) offers greater bandwidth, high signal attenuation limits transmission distance. These challenges present significant obstacles to building a comprehensive 5G infrastructure.
The E-Band: A Breakthrough Solution for 5G Infrastructure
The E-band (71-76 GHz and 81-86 GHz) emerges as a strategic solution. Its superior technical characteristics enable the deployment of high-speed transmission lines over short distances, making it ideal for densely populated urban areas, data centers, and 5G radio access networks. This addresses the limitations of existing frequencies, paving the way for faster transmission speeds and more stable connections.
The Significance of Circular No. 02/2025/TT-BKHCN
Circular No. 02/2025/TT-BKHCN is critically important in establishing the legal framework for the use of the E-band in Vietnam. The circular facilitates the deployment of ultra-high-speed transmission infrastructure, an essential element for nationwide 5G network development. This is not just a significant step in frequency management, but also a catalyst for the development of high-speed wireless transmission systems.
Strategic Vision and Future Outlook
The detailed E-band planning demonstrates a strategic vision for managing frequencies and promoting the development of Vietnam’s 5G network. This advancement will meet the increasing bandwidth demands of 5G networks and future applications, helping to build a robust “information superhighway” for Vietnam’s next-generation telecommunications infrastructure, creating a foundation for sustainable digital economy growth.
Conclusion
Circular No. 02/2025/TT-BKHCN represents a significant step forward, opening new opportunities for developing 5G infrastructure in Vietnam. Early implementation of this plan will yield substantial benefits for the country’s digital economy development and the lives of its citizens.
