The Ministry of Science and Technology has issued a plan to re-auction the right to use radio frequencies for the 703-713 MHz and 758-768 MHz bands (B1-B1' band block) and the 723-733 MHz and 778-788 MHz bands (B3-B3' band block).
The starting price for the B1-B1' and B3-B3' frequency bands is over 1.95 trillion VND; this will be determined by direct voting with a bidding increment of 20 billion VND.
The winning bidder will be granted a 15-year license to use the frequency band. The company that won the auction for the B2-B2' frequency band (713 - 723 MHz and 768 - 778 MHz) is not allowed to participate in the auction for the B1-B1' and B3-B3' frequency bands.
Within 30 days from the date the Ministry of Science and Technology publicly announces the auction plan, organizations wishing to participate in the auction for the right to use radio frequencies in the B1-B1' and B3-B3' frequency bands must submit an application for confirmation of eligibility to participate in the auction to the Telecommunications Department (Ministry of Science and Technology).
The B1-B1' and B3-B3' frequency bands are planned for the deployment of mobile communication systems according to the IMT Advanced standard and its subsequent versions, using frequency division duplex (FDD) method, as stipulated in Circular No. 19/2019 dated December 25, 2019, issued by the Minister of Information and Communications on the planning of the 694-806 MHz frequency band for Vietnam's IMT mobile communication system.
At the end of March 2025, the Radio Frequency Department (Ministry of Science and Technology) announced a plan to re-auction the right to use radio frequencies for the B2 - B2' band. The reason for the re-auction is that previously, at the end of December 2024, the Radio Frequency Department announced an auction for the B1-B1', B2-B2', and B3-B3' bands, but it was unsuccessful due to a lack of participating businesses.
At the re-auction held on May 20th, after two rounds of bidding, Viettel Group won the bid for the B2-B2' frequency band. Viettel will deploy 4G and 5G mobile broadband internet access services, providing high speeds and low latency for entertainment, remote work, online learning, IoT (Internet of Things) services, and supporting platforms and applications such as smart cities, smart agriculture, and smart traffic management…
Frequency bands are crucial for 4G and 5G networks.
The value of a frequency depends on whether its operating range is wide or narrow and whether the frequency is low or high. The wider the frequency range, the higher the data transmission speed. The lower the frequency range, the further the mobile signal travels.
Due to its low frequency, the 700 MHz band is considered to be of very high commercial value. Compared to the 900 MHz, 1800 MHz, or 2100 MHz bands, the 700 MHz band has a significant advantage in terms of signal transmission capabilities.
Globally, the 700 MHz frequency band is widely used in 4G and 5G mobile networks. It is one of the crucial bands that helps optimize the speed and coverage of these next-generation mobile networks.
Utilizing the 700 MHz frequency band helps mobile operators improve the quality of mobile services, especially in high-density areas like large cities, reducing network congestion and providing more stable services for users.
Before the 700 MHz frequency band was auctioned, it was used for analog television services. However, with the transition to digital terrestrial television in Vietnam, this band was transferred to mobile network operators to serve telecommunications services.
The auction and early deployment of the 700MHz frequency band is one of the concrete solutions to effectively implement the Party's major policies and orientations, especially to realize the goal of developing digital infrastructure as clearly stated in Resolution 57 of the Politburo on breakthroughs in science and technology development, innovation and national digital transformation.
