AI-Native Networks: Why 6G Will Be Built on Intelligence, Not Just Speed

While telecommunications companies worldwide rush to complete 5G deployments, research labs and industry consortiums are already deep into developing the next revolution: artificial intelligence-driven 6G networks that will fundamentally change how wireless systems operate.

Unlike previous generational leaps that primarily delivered speed improvements, 6G represents a paradigm shift toward AI-native architecture where artificial intelligence becomes integral to every layer of network operation rather than an afterthought. Commercial 6G systems are expected to launch around 2030, with technical specifications finalized by 3GPP Release 21 in 2028.

The convergence of AI and communication technologies will create 6G networks that make hyperconnectivity and immersive experiences an everyday reality for consumers. Industry experts anticipate theoretical peak speeds reaching 1 Tbps-potentially 100 times faster than 5G-alongside sub-millisecond latency and the ability to simultaneously support millions of connected devices per square kilometer.

The defining characteristic of 6G lies in its AI-native design philosophy. 6G technology is still in its initial stages, but it's already shaping up with enhanced capacity, ultra-low latency, ultra-high reliability, and improved privacy. Rather than retrofitting AI capabilities onto existing network architectures, 6G embeds intelligence from the ground up through distributed AI agents that optimize network performance in real-time.

AI-RAN (AI-Radio Access Network) technology exemplifies this approach, with AI embedded directly into base stations and network equipment to analyze traffic patterns and route data through optimal pathways. The AI-RAN Alliance has grown to 75 members across 17 countries, including major players like NVIDIA, Samsung, Ericsson, and SoftBank.

At MWC 2025, the AI-RAN Alliance showcased ten demonstrations illustrating how AI could optimize network performance, enhance energy efficiency, and enable new levels of automation. These practical implementations span several key areas:

Autonomous Network Management: AI-powered networks will detect abnormal traffic patterns and potential security threats in real-time, functioning like an immune system that automatically identifies problems and implements solutions without human intervention.

Energy Optimization: AI can reduce energy consumption by dynamically adjusting base station power output based on demand patterns, directing resources only where needed and minimizing waste during low-traffic periods.

Edge Intelligence: Edge computing brings computational tasks closer to data sources, improving latency, privacy, and resource distribution across the network, enabling processing without sending data to distant servers.

Samsung released its latest 6G white paper "AI-Native & Sustainable Communication" in February 2025, emphasizing AI integration throughout telecommunications systems. "We are intensifying our 6G research efforts, focusing on AI-enabled communication technologies and sustainable networks," said Charlie Zhang, Senior Vice President of Samsung's Advanced Communications Research Center.

NVIDIA unveiled partnerships with industry leaders T-Mobile, MITRE, Cisco, and others on developing AI-native wireless network hardware, software and architecture for 6G. "Next-generation wireless networks will be revolutionary, and we have an unprecedented opportunity to ensure AI is woven in from the start," said Jensen Huang, NVIDIA's CEO.

AI's energy-intensive nature, combined with the growing demand for AI-based applications, raises concerns about the potential increase in training costs during the transition to 6G. The telecommunications industry must address several critical challenges:

Power Consumption: The urgency of addressing climate change amplifies the need to enhance 6G's energy efficiency, requiring advances in silicon technology and cooling systems for data centers.

Infrastructure Complexity: 6G networks will be immensely complex, requiring more deployment time, cost and management efforts, particularly as operators must maintain existing 5G services during the transition.

Standardization Coordination: The O-RAN Alliance is working with 3GPP to coordinate efforts towards a unified vision for 6G, ensuring specifications remain consistent and complementary across different standards bodies.

South Korea, which launched the world's first commercial 5G network in April 2019, continues positioning itself as a 6G pioneer. As of March 2024, South Korea had approximately 33.4 million 5G subscribers, providing valuable deployment experience that informs 6G development.

In late 2023, South Korea's Ministry for Science and ICT announced a $325 million initiative to develop "pre-6G" technology, aiming to be the first country to deploy commercial 6G services as early as 2028.

The largest number of 6G patents have been filed in China, while ten countries including Australia, Canada, Finland, France, Japan, South Korea, Sweden, the United Kingdom, and the United States signed a joint statement in February 2024 endorsing principles for 6G development focused on security, openness, and resilience.

3GPP will begin 6G requirements work in 2024 during Release 19, with first specifications expected by end of 2028 in Release 21. As Adrian Baschnonga from EY notes, "6G will play an important role in scaling AI workflows, underlining the symbiotic relationship between these two frontier technologies".

6G will provide super communication and ubiquitous information, and converge computing services, thus being the base for an interconnected and converged physical and digital world. The technology promises to enable everything from holographic communications and digital twins to massive IoT deployments and real-time remote surgery.

The transition to 6G represents more than technological evolution-it marks the beginning of truly intelligent networks that can adapt, optimize, and evolve autonomously. As the industry works toward 2030 commercial deployments, the foundation being laid today will determine whether 6G delivers on its transformative potential or becomes another incremental upgrade. With AI as its cornerstone rather than an accessory, 6G appears positioned to fulfill the former.
