The telecom committee of the National Broadcasting & Telecommunications Commission (NBTC) has approved a previously announced plan from its subcommittee to auction two mobile licences apiece in the 1800MHz and 900MHz spectrum bands, according to committee chairman Settapong Malisuwan, cited by Thai newspaper The Nation. The two 1800MHz licences to be auctioned in August this year will comprise 12.5MHz bandwidth each, with validity of 19 years, and participants may bid for only one of the 12.5MHz blocks, the committee confirmed. In the 900MHz auction scheduled for November, one licence is being offered with 10MHz bandwidth alongside a second 7.5MHz concession block, with both 900MHz band licences carrying a 15-year validity, while bidders may compete for both 900MHz permits on offer. Settapong was quoted as saying that the strategy was aimed at encouraging more players to enter the auction. The committee also approved proposals that winners must roll out networks covering 40% of the population within four years of being licensed.
