DTAC will likely bid for more bandwidth in the upcoming 1800MHz spectrum auction despite agreeing to a deal to use TOT's 2300MHz frequencies on concession. Financial stress in the sector, resulting from 4G price competition could weigh on the ability of other operators to buy more spectrum. The National Broadcasting and Telecommunications Commission (NBTC) will auction three blocks of 2x15MHz spectrum in the 1800MHz band in August 2018, in a move likely to attract the interest of DTAC, whose concessions to use spectrum from CAT will expire in September 2018. While additional spectrum will address problems meeting growing data demand, elevated financial stress in the sector due to aggressive 4G price competition will colour other operators' interest in the auction. Telenor-backed DTAC has also recently signed an agreement with state-owned TOT to jointly develop a 4G TD-LTE network in the 2300MHz band, although the network will only provide limited services in the near term.
