On the afternoon of March 19, Vietnam Posts and Telecommunications Group (VNPT) announced the successful auction results of the frequency usage rights for the C2 band (3700-3800 MHz) after 17 auction rounds.
According to experts, 3700-3800 MHz is a mid-range frequency band that many major carriers in the world are looking for and using thanks to its advantages of large bandwidth, strong speed, low latency and effective investment costs, meeting the most advanced 5G networks today.
Along with the 3700 - 3800 MHz frequency band that was just successfully auctioned, VNPT owns the 1800 MHz frequency band, which is considered a great advantage in promoting the 5G network in the coming time, while creating the premise for the development of the 6G network in the future.
In terms of technology, having the above frequency bands in hand helps VNPT have many options for network equipment, optimize the cost of deploying 5G nationwide, and meet the strategy of turning Vinaphone into a high-speed 5G network in Vietnam.
A representative of VNPT Group said that the spectrum auction process is the first step according to the State's regulations on 5G deployment in Vietnam. After winning the auction for block C2, VNPT will prepare to soon commercialize 5G.
To increase efficiency, the company revealed its plan to deploy a cooperation model, sharing infrastructure with the network operator that won the 3800-3900 MHz band in the upcoming re-auction to optimize the resources of the telecommunications company, while providing customers with the best experience with 5G services.
VNPT also plans to deploy commercial 5G in 2024.
Previously, the auction of the C3 band (3800-3900 MHz) scheduled for March 14 failed because a business did not participate in the auction.
With the results on March 19, VNPT became the second mobile network operator in Vietnam to have 5G frequency, after Viettel (successfully auctioned the "golden frequency" 2500-2600 MHz on March 8). Currently, only MobiFone, Vietnamobile and Gtel do not have 5G frequency. Of these, it is likely that Vietnamobile and Gtel do not have plans to deploy 5G in the short term due to economic efficiency calculations.
According to the Massachusetts Institute of Technology (USA), the higher the frequency band, the larger the bandwidth, the stronger the speed, the lower the latency and the higher the capacity, but the coverage will be limited and easily obstructed by large physical objects such as buildings and trees.
Currently, the world's 5G frequency bands are divided into 4 groups including low frequency bands (under 1000 MHz), mid-range band 1 (1000 - 2600 MHz) and mid-range band 2 (3500 - 7000 MHz), and finally high frequency bands (24000 - 48000MHz).
Each type of frequency band has different advantages and disadvantages. Therefore, in reality, most network operators try to use many different types of frequency bands at the same time to meet customer needs and optimize service quality.
