Vietnam’s Ministry of Information and Communications (MIC) has requested input from the country’s telecom providers to design a plan for a 4G frequency band, VietNamNet reports. Responsibility for the task has been assigned to the Department of Wireless Frequency and Telecommunications, although the MIC will design the plan after input has been collected by the end of this year. Vietnam’s telecoms firms will then be allowed to choose whether to adopt WiMAX or Long Term Evolution (LTE) technology. According to TeleGeography’s GlobalComms Database, a number of telecoms operators have already carried out WiMAX trials in Vietnam. The first pilots were launched by state-owned Vietnam Posts and Telecommunications (VNPT) in the mountainous Lao Cai region in October 2006, while military-owned Viettel began its trial in Hanoi in December 2006. In March 2008 the MIC licensed five telcos – FPT Telecom, EVN Telecom, Viettel, Saigon Postel and VNPT’s wholly-owned subsidiary Vietnam Data Communications Company (VDC) – for a year-long trial of mobile WiMAX. FPT, EVN and Viettel were granted temporary spectrum allocations in the 2.3GHz-2.4GHz range, while VDC was given a block in the 2.5GHz band.
