It was reported by the Bangkok Post on March 22 that the  National Broadcasting and Telecommunications Commission (NBTC)  approved all three master plans on March 21 governing spectrum, telecommunications and broadcasting.

The NBTC also reportedly endorsed the periods within which the state-owned communications firms have to return radio, television, and mobile spectrum frequencies that do not have an expiry date: Radio spectrum must be returned within five years, television spectrum within ten years, and mobile spectrum within fifteen years. Spectrum frequencies used by concessionaires are to be returned once the concession expires.

Publication of the three master plans in the Royal Gazette by the NBTC is expected in early April.  For more information on Thai telecommunications law, click here.
