The National Broadcasting and Telecommunications Commission (NBTC) has approved three draft announcements to enhance radio frequency use and technical standards for wireless microphones.

Approved during Meeting No. 31/2025, chaired by Air Chief Marshal Dr. Thanapan Harijaroen, the measures aim to support growing wireless microphone demand for events, broadcasting, and conferences.

Key updates include:

• Enhanced Technical Standards: Supporting wireless microphone systems with channel bandwidths greater than 200 kHz to enable multi-channel operation (Wireless Multichannel Audio System – WMAS).

• Expanded use of the 1880–1900 MHz band for DECT technology, aligning with international practices.

• Updated Safety and Performance Requirements: Modernized standards for electrical safety and performance to match current wireless technologies.

Dr. Thanapan said the move will ease frequency congestion and strengthen Thailand’s position as a hub for international events and digital broadcasting. Want to know more about Thailand NBTC regulatory updates, feel free to contact us at info@nanotechsol.com.
