As the global telecom industry begins to look beyond the 5G horizon, a pivotal conversation is shaping the future of connectivity. Recently, at the Global 6G Conference in Nanjing, China, insights from industry veteran Chih-Lin I, chief scientist of wireless tech at China Mobile, provided a roadmap for the next decade of mobile technology.
The 5G Experience: Fulfilling a Different Mission
Many consumers around the world have wondered why the leap from 4G to 5G hasn't felt as revolutionary as promised. According to the expert, this perception stems from a fundamental shift in purpose. While 4G largely satisfied the "must-have" needs for everyday communication and entertainment, 5G was designed with a different mission in mind.
"I cannot think of a must-have service or application that were not already satisfied [by 4G]," she noted in an exclusive interview. Instead, she explained, 5G's primary focus has been on serving vertical industries—from manufacturing and logistics to healthcare—by building platforms that share resources across diverse, specialized needs.
6G's Blueprint: From a Triangle to a Hexagon
The technical framework for 5G was built around a triangle of capabilities: massive Internet of Things, enhanced mobile broadband, and ultra-reliable low-latency communication. For the next generation, this model is expanding dramatically.
"For 6G, instead of a triangle, it actually has a hexagon with another three points: sensing, AI … (and) coverage extension," she explained. This expanded capability set hints at a network designed not just for connection, but for intelligent, integrated interaction with the physical world.
The Core of 6G: AI as Its DNA
The most transformative shift, according to the scientist, is the intrinsic role of Artificial Intelligence. In previous generations, AI was an add-on tool used to optimize network performance.
"For 6G, [AI] will be something that this new generation will be born with. It's from inside," she stated. This "AI-native" approach works in two key directions: using AI to optimize the 6G network itself, and designing the network from the ground up to serve and process the colossal data demands of future AI applications.
She also highlighted a critical design challenge: 6G infrastructure must be agile enough to keep pace with the rapid evolution of AI technology itself. Unlike the traditional 10-year telecom cycle, AI advances at a blistering speed. Therefore, 6G must be built with "forward compatibility" to adapt to unforeseen breakthroughs.
A Journey into the Unknown
Looking ahead, the expert described the current phase as both exciting and full of potential. "I really think it's a very exciting time because we have so many questions," she concluded. "There is a lot of unknown, a lot of uncertainty, and simultaneously, a lot of potential. It's a very enjoyable journey to look forward to."
As research intensifies globally, these early insights from China's telecom sector underscore a broader shift: the next generation of wireless technology is being reimagined not just as faster pipes, but as the foundational nervous system for an AI-driven future.
