The National Broadcasting and Telecommunications Commission (NBTC) has disclosed that the digital terrestrial TV (DTT) signal will be disrupted for some Thai areas from September, as DTT providers start returning portions of their 700MHz spectrum to the authority, the Bangkok Post writes. As previously noted by TeleGeography’s CommsUpdate, the NBTC completed its 5G multiband spectrum auction in February this year, raising around THB100.5 billion (USD3.2 billion) from the sale of 48 concessions for spectrum in the 700MHz, 2600MHz and 26GHz bands. The auction for the three 700MHz authorisations lasted 19 rounds, with the airwaves sold to AWN (one licence) and CAT (two concessions) at THB17.15 billion apiece. NBTC vice-chairman Natee Sukonrat said that initial disruptions to the DTT signal are expected in the Southern region from September, Bangkok and the surrounding areas (from 5 October), Northern region (October), Northeastern region (November) and Central region (December). The 700MHz range is scheduled to be used for telecoms purposes from 15 January 2021.
