Thailand’s second-largest cellco by subscribers Digital Total Access Communication (DTAC) yesterday switched on commercial 1800MHz-based 4G LTE mobile broadband services in downtown Bangkok, using refarmed GSM frequencies, augmenting its existing 2100MHz LTE services. DTAC, part of Norway’s Telenor Group, is the first in Thailand to launch 1800MHz 4G services, having recently received regulatory permission for technology-neutral usage of the band, whilst rivals are waiting for 1800MHz 4G licences up for grabs in an auction scheduled for this month. Quoted by local newspaper The Nation, Prathet Tankuranun, DTAC’s chief technology officer, confirmed that the new LTE service uses 10MHz of bandwidth in the 1800MHz range, compared to the existing 5MHz allocated to DTAC’s 2100MHz LTE network. Mobile data traffic demand in downtown Bangkok reportedly accounts for half of all traffic in DTAC’s existing 4G-covered areas in Greater Bangkok.
