New Base Transceiver Stations to be in central areas of cities and provinces with high data demand, to improve 4G network quality.

Viettel has announced plans to deploy nearly 10,000 Base Transceiver Stations (BTSs) in central areas of cities and provinces with high data demand, in order to improve 4G network quality.

The 4G BTSs are on the 2100MHz band, which has just been licensed by the Ministry of Information and Communications (MoIC) to 15 large cities and provinces with high demand for data, such as Hanoi, Ho Chi Minh City, Da Nang, Hai Phong, and Quang Ninh. Installation is expected to be completed by the middle of this year.

Viettel is also removing 2G subscribers from the 1800MHz band, taking the entire band for the 4G network. When completed, Viettel’s high-speed 4G network capacity will increase 25 per cent compared to currently because it is not shared with the 2G network.

Viettel therefore becomes the only network in Vietnam deploying 4G network on both the 1800MHz and 2100MHz bands.

Many new technologies and solutions will also be implemented by Viettel to improve 4G service quality. More than 1,000 small cell broadcast stations will be installed. A series of devices dividing the coverage area is being implemented by Viettel in crowded areas such as pedestrian streets, stadiums, and festival areas.

Mr. Dao Xuan Vu, General Director of the Viettel Network Corporation, said it currently has the largest number of 4G subscribers and data consumption trends continue to increase rapidly. “In the absence of a dedicated band, these technical solutions help to improve the speed of Viettel’s 4G service,” he added. “When completing the upgrade plan, Viettel’s 4G network capacity will increase from 25 to 50 per cent depending on the area, and users’ 4G data rate will also increase by an average of 1.3-1.5 times compared to present.”

Viettel currently has the largest network infrastructure in Vietnam, with nearly 130,000 BTSs. The newly-deployed 4G network is also equipped with nearly 50,000 base stations.

4G services have been officially provided in Vietnam since 2017 on the 1800MHz band together with the 2G network. After two years of supply, mobile data consumption trends have boomed, and network operators face a shortage of bandwidth, affecting overall speed.

Operators have also proposed to the MoIC that bidding for the 2600MHz band reserved for 4G services be allowed. Due to concerns about legal barriers, however, the proposal has not been implemented as yet.
