New Procedures for IMT Services of Thailand NBTC

Thailand’s NBTC held its second public hearing on a proposed announcement outlining the criteria and procedures for allocating frequency bands for IMT services.

The second public hearing was held on April 1, 2025, and was attended by National Broadcasting and Telecommunications Commission (NBTC) Chief Torapong Selanon, Assoc. Prof. Dr Sompop Phuriwikraipong, and other senior officials.

The main objective of the draft new procedures for International Mobile Telecommunications (IMT) services of Thailand NBTC announcement is to assign frequency bands that will enhance high-speed communications—an essential factor in advancing Thailand’s economy and society.

Why Is NBTC Introducing New IMT Spectrum Allocation Procedures?

The proposed IMT spectrum allocation procedure is part of the NBTC’s efforts to support the expansion of mobile broadband and digital connectivity in Thailand. As mobile data consumption continues to increase and the number of connected users grows, adequate spectrum resources are required to maintain network quality and service reliability.

In addition, the NBTC is supporting the ongoing expansion of 5G networks across Thailand by ensuring the availability of appropriate frequency bands for coverage and capacity. Low-frequency bands can help expand network coverage, particularly in rural areas. Meanwhile, mid- and high-frequency bands provide the capacity needed to support increasing traffic volumes and advanced digital services.

This proposed allocation process represents the NBTC’s effort to manage the spectrum efficiently. The allocation balances the needs of network operators, consumers, businesses, and the broader telecommunications sector. In this way, the NBTC can maximize the utilization of the spectrum.

This initiative also supports Thailand’s broader digital economy goals. Improved cellular connectivity can contribute to the development of emerging digital technologies and services. 

Consequently, Thailand can adapt to smart manufacturing, Internet of Things (IoT) applications, cloud-based services, smart city projects, and other innovations that rely on high-speed communications. Through this IMT frequency band allocation, Thailand aims to strengthen its digital infrastructure and lay the groundwork for future technological growth.

Frequency Bands Covered

Key Topics Discussed During the Public Hearing

The hearing concentrated on several specific frequency bands: 850 MHz, 1500 MHz, 1800 MHz, 2100 MHz, 2300 MHz, and 26 GHz. The proposed announcement sets out guidelines and procedures for authorizing the use of these bands for international mobile telecommunications, which could significantly influence the advancement of 5G networks and other mobile technologies.

The proposed spectrum allocation supports the expansion of telecommunications services and the development of next-generation 5G networks. The NBTC stressed the need for a fair, competitive, and efficient auction process that maximizes public benefit and resource utilization.

Key topics discussed at the hearing included which frequency bands should be put up for auction, auction mechanisms, pricing structures, payment options for new operators, and consumer protection requirements.

The session also covered social considerations, such as safeguarding the rights of vulnerable populations, including the elderly and people with disabilities.

What Happened After the Public Consultation?

The public consultation on the spectrum allocation plan for International Mobile Telecommunications (IMT) services concluded in April 2025. After reviewing the feedback received during the consultation period, the NBTC established an official schedule for the spectrum allocation process.

The auction for the IMT frequency bands was held on June 29, 2025. This is a significant milestone in Thailand’s efforts to expand spectrum resources for mobile broadband services and future network development.

The auction framework focuses on the 850 MHz, 1500 MHz, 2100 MHz, and 2300 MHz frequency bands. These frequencies are considered critical for improving network coverage, capacity, and overall service quality.

The progress of this process demonstrates Thailand’s commitment to transparent spectrum management and long-term telecommunications development. 

What Could These Changes Mean for Mobile Network Operators?

The allocation of additional IMT spectrum has a direct impact on mobile network operators. The allocation of additional IMT spectrum could provide mobile network operators with access to additional frequency resources needed to support growing mobile data demand.

This additional spectrum can help operators increase network capacity, reduce congestion, and deliver better service quality. This will accommodate the ever-growing number of users and connected devices.

The availability of various frequency bands can also support broader network coverage and more efficient use of spectrum resources. These bands can help operators balance their coverage and performance.

Furthermore, the spectrum allocation process can drive further investment in 5G and 5G-Advanced technologies in the future. As a result, operators can enhance network capabilities, introduce new digital services, and support digital transformation initiatives in Thailand.

Impact on Equipment Manufacturers and Type Approval Applicants

The spectrum allocation may have implications for manufacturers and importers planning to place mobile devices on the Thai market. In this context, equipment manufacturers can increase the use of devices that support the relevant bands.

When submitting devices operating on the relevant frequencies, certificate applicants must ensure that the devices meet Thailand’s technical requirements. This is demonstrated by a test report submitted with the application.

Before entering the Thai market, manufacturers and importers need to check the band support of the devices being submitted. Additionally, they need to monitor applicable NBTC regulations to ensure the devices meet the latest standards.
