Thailand Frequency Plan 2026-2028: NBTC Spectrum Master Plan Update

Thailand's spectrum governance is entering a new phase. The National Broadcasting and Telecommunications Commission (NBTC) has prepared a draft announcement to revise the country's Frecuency Management Master Plan, introducing a defined 2026-2028 timeframe for the first time. The move is designed to synchronize national spectrum planning with major international developments and to ensure that Thailand's policies reflect current usage, technology trends, and forward-looking priorities.

For manufacturers, importers, and certification bodies operating in the Thai market, this update signals a more predictible and internationally harmonized regulatory roadmap one worth tracking closely.

Why the NBTC is Updating the Thailand Frequency Plan 2026-2028

The previous version of the master plan lacked a defined timeframe, which created uncertainty for long-term planning. By establishing a fixed 2026-2028 window, the NBTC is bringing structure and predictability to its spectrum roadmap.

The most significant driver behind the revision is international aligment. The updated plan is built to correspond with the 2027 World Radiocommunication Conference (WRC-27), the global event where ITU member states negotiate changes to interantional spectrum allocations. The plan also anticipates the 2029 Radio Regulations, which are expected to be promulgated in January 2028.

By synchronizing its national planning cycle with these international milestones, Thailand aims to remain consistent, prepared, and responsive as global spectrum rules evolve. This forward-looking approach helps the country adapt quickly once new international allocations are finalized.

What the Updated Master Plan Covers

The revised master plan updates its content to reflect current spectrum usage, emerging technology needs, and anticipated international changes tied to WRC-27 outcomes. In practice, this means the document will serve as the reference framework that guides how spectrum is allocated, managed, and proritized across telecommunications and broadcasting sectors through 2028.

What This Means for Manufacturers

While the master plan is primarily a high-level governance and policy document rather than a product-level technical standard, its downstream effects matter for anyone placing wireless or RF products on the Thai market:

A clearer, time-bound roadmap helps manufacturers anticipate which bands may be reallocated, refarmed, or newly opened in the coming years, supporting better long-term product planning. Because the plan is tied to WRC-27, companies can expect Thailand's future band allocations to move closer to global harmonization—reducing the likelihood of Thailand-specific spectrum quirks over time. Manufacturers with multi-year product roadmaps (especially in mobile, IoT, and broadcasting) should monitor how the finalized plan treats the bands relevant to their portfolios, since allocation decisions ultimately shape which technical standards and approvals apply.

In short, this update doesn't impose immediate product changes, but it sets the strategic direction that future technical requirements will follow.

Certification Impact Summary

The master plan itself does not directly alter type approval procedures or technical certification requirements. However, it functions as the foundation from which specific frequency plans and technical standards are later derived. As the NBTC implements the 2026–2028 roadmap and integrates WRC-27 outcomes, subsequent announcements may introduce new band designations or revise existing allocations—changes that can eventually flow through to type approval, licensing, and conformity requirements. Companies should treat this update as an early-warning indicator and prepare to reassess certification strategies as detailed band-level rules emerge.

Timeline + Required Actions

Public consultation window: May 18 – July 6, 2026

Linked international milestone: WRC-27 (2027)

Anticipated 2029 Radio Regulations: Expected January 2028

Stakeholders and the general public can submit feedback during the consultation period through multiple channels, including Google Forms, email, registered mail, or in-person submission at the NBTC Office.

Recommended actions:

First, review the draft master plan and identify the frequency bands relevant to your products or services. Second, prepare and submit feedback before the July 6, 2026 deadline if any proposed allocations could affect your operations. Third, map your product roadmap against the WRC-27 timeline so you're positioned to respond to band-level changes as they are finalized. Fourth, establish internal monitoring of subsequent NBTC announcements, since detailed technical standards and certification rules will follow the master plan rather than appear within it.
