TOTAL ACCESS Communication (DTAC) Monday kicked off 4G cellular service on its existing 1800-megahertz band to complement its 4G service on its 2.1-gigahertz band.
DTAC is the first in the country to roll out 4G-1800MHz, starting with downtown Bangkok, which has the heaviest data traffic, accounting for half of all 4G areas in Greater Bangkok.
Prathet Tankuranun, chief technology officer, said Monday the new service uses 10MHz of bandwidth on 1800MHz, the widest used frequency for 4G worldwide. The company’s 4G-2.1GHz service uses 5MHz.
