The gNodeB transceiver made by Viettel includes both software and hardware. The device was developed within six months, starting in June 2019.
After eight months, since the telecom carrier used a foreign-made device to test the 5G network, Viettel has helped Vietnam to master 5G technology.
A representative of Viettel said that in the global market, the five suppliers of network infrastructure devices for 5G include Ericsson, Nokia, Huawei, Samsung and ZTE. Viettel will now become the sixth provider of the 5G device.
“The 5G network will determine the success of the digital economy,” said Viettel general director Le Dang Dung, adding that many countries are using 5G services to strengthen their science-technology position on the global market and develop their economies.
