Viettel, Vietnam’s largest mobile operator by subscribers, has carried out trials of Dual Carrier (DC)-HSPA+ technology in 13 cities and provinces in the south west of the country, VnEconomy reports. The military-run telecoms company aims to complete the upgrade of its 3G network with DC-HSPA+ in the remaining parts of the country early next year, enabling its customers to access maximum download speeds of 42Mbps. Work to upgrade Viettel’s approximately 26,000 3G base transceiver stations (BTS) is being carried out in cooperation with Qualcomm Indochina.
As reported by CommsUpdate last month, one of Viettel’s main rivals announced it had successfully tested DC-HSPA+ technology in the three major cities of Hanoi, Da Nang and Ho Chi Minh City. Vinaphone, which is a subsidiary of state-owned national PTO Vietnam Posts and Telecommunications (VNPT), said it would begin rolling out the faster speeds across its nearly 13,000 3G base stations nationwide in early 2015, adding that it was also working with equipment suppliers to further boost data rates up to 84Mbps in the future.
