Thailand’s mobile market leader by users Advanced Info Service (AIS) intends to launch commercial 4G LTE services by mid-December, according to its CEO Somchai Lertsutiwong, quoted by the Bangkok Post. AIS, through its subsidiary Advanced Wireless Network (AWN), won one of two 1800MHz licences auctioned last month, alongside rival True Corp, which operates an existing 2100MHz-based LTE service. AIS’ other main rival, DTAC has already introduced both 2100MHz and 1800MHz LTE services. The AWN unit has now handed the National Broadcasting & Telecommunications Commission (NBTC) the necessary first-half payment installment for its 1800MHz licence, clearing the way for commercial launch. Mr Somchai said AIS would provide 4G tariff rates in line with the NBTC’s regulations, whilst he said he could not elaborate on AIS’ 4G business plans and marketing strategy due to the NBTC’s ‘silent-period’ restriction, as the sector gears up for another technology-neutral spectrum auction, this time in the 900MHz band, next month.
