Thailand’s  National Broadcasting and Telecommunications Commission (NBTC) has instituted a spectrum cap  limiting all mobile operators to a maximum of 60 megahertz of total spectrum, a move that will shape bidding for Long Term Evolution 4G spectrum in upcoming auctions.

The cap means Total Access Communication (DTAC), owned by Telenor, the second-biggest Thai mobile operator, would be unable to bid for Long Term Evolution 4G spectrum.

DTAC already has licenses to use about 75 MHz of spectrum.

In the upcoming auction, four 4G licenses are available, two licenses of 12.5 MHz of bandwidth in the 1800-MHz band, and two of 10 MHz each on the 900-MHz band.

The 1800-MHz auction presently is scheduled to begin Nov 11, 2015, while  the 900-MHz auction will commence on Dec 15, 2015.
