Thailand Enters a New Era of Intelligent Networks

AIS has propelled Thailand into a new era of intelligent networks with the launch of "5G-ADVANCED," marking a significant milestone as the first in Southeast Asia to deploy this advanced technology. This upgrade, achieved through collaboration with global partners and the integration of Artificial Intelligence (AI), aims to redefine network speed and efficiency. The initiative represents a substantial leap for the nation's telecommunications infrastructure, elevating 5G capabilities to a new standard of intelligent connectivity. By employing Downlink 3CC and Uplink 2CC technologies for the first time, AIS is enhancing network performance across downloads, uploads, and response times, positioning Thailand for the next generation of digital services and future advancements toward 6G. The core of this advancement lies in the synergy of "Partnership + AI + Innovation," creating a "5G-ADVANCED" standard. This is realized through 5G SA Carrier Aggregation, which combines multiple frequency bands—specifically 3CC using 700 MHz, 2100 MHz, and 2600 MHz, and 2CC using 700 MHz and 2600 MHz—to deliver demonstrably superior user experience.

Unlocking Enhanced Speeds and Intelligent Management

The technological enhancements translate into tangible performance gains. Users can expect download speeds to increase by up to 1.5 times through the 5G SA Downlink 2CC/3CC configuration. Equally significant is the boost in upload speeds, which can double with the 5G SA Uplink 2CC technology. Central to this upgrade is the deployment of AI for autonomous network management. This intelligent system continuously analyzes network density and adapts in real-time to optimize performance and ensure seamless connectivity across all usage scenarios. This proactive approach is crucial for handling the increasing demands of sophisticated digital applications. These improvements are designed to benefit a wide range of activities, from high-definition video streaming and online gaming to live broadcasting and cloud-based work, providing a smoother, more reliable digital experience for customers using compatible devices.

Strategic Rollout and Evolving User Behavior

The rollout of 5G-ADVANCED is being implemented in phases. Currently, 5G SA Downlink 3CC is operational in the Sathorn and Bang Rak districts of Bangkok, with plans to expand to other key areas within the capital and its surrounding provinces by 2026. Meanwhile, 5G SA Downlink 2CC services are already available across Bangkok, its metropolitan area, and major cities nationwide. The Uplink 2CC service, initially launched in the northeastern region and Bangkok metropolitan area, is also slated for nationwide city coverage by 2026. This phased approach ensures that the advanced capabilities are gradually introduced while maintaining service quality. This strategic network evolution is partly driven by a shift in Thai consumer behavior. While downloading content was paramount two to three years ago, there is now a growing emphasis on uploading data, particularly with the rise of AI applications and live streaming. AIS is responding to this trend by enhancing upload capabilities to meet these emerging needs.

The Role of Partnerships and Future-Proofing

AIS emphasizes that this network upgrade is not merely about increasing speed or base station numbers. It is about building new national capabilities through strategic collaborations with global device partners and the intelligent application of AI for network management. This forms the bedrock for future autonomous network systems. "Our mission is to strengthen and modernize Thailand's digital infrastructure, making it ready for the growth of the digital economy," stated Wasit Wattanachot, Head of Nationwide Operations and Technical Support Business Unit at AIS. "The mobile network is the lifeblood of connectivity, linking people, businesses, industries, government, and digital services. Therefore, network development today is not just about speed or signal strength; it's about creating new capacities for the country and delivering the best digital experience to our customers." The company is working with a broad spectrum of device manufacturers, including Apple (primarily iPads), Oppo, Honor, Nokia, Realme, Vivo, Samsung, Xiaomi, and Google Pixel, among others. Approximately 90% of compatible devices are Android smartphones, with users able to verify model compatibility on AIS's website.

AI for Security and Digital Infrastructure

Beyond performance enhancements, AIS is leveraging AI to bolster network security. Services like AIS SAFE CONNECT and the *1185# short code for reporting suspicious numbers are being deployed to combat the rising tide of technological crime. This focus on security is integral to maintaining user trust and safety as the network expands and digital activities become more complex. It aligns with AIS's broader vision of contributing to Thailand's sustainable development as a national digital infrastructure. the emergence of the "5G+" symbol on mobile devices, indicating that users in serviced areas with compatible equipment are accessing the upgraded network without additional subscription fees, signifying a seamless transition to enhanced services.

The bottom line
