Driven by the tides of technological advancement, the Internet of Things (IoT) is transforming our world at an unprecedented pace. From smart homes to industrial automation, from intelligent cities to autonomous driving, IoT’s reach has extended into every corner of human life.
Yet, even as 5G continues its global rollout, a grander technological revolution is quietly unfolding—6G research has begun, with commercialization expected by 2030. As a trailblazer in this domain, China is spearheading the integration of IoT and 6G with remarkable speed and ambition. 6G is not merely an upgrade to communication technology; it is the key to unlocking IoT’s full potential.
How will it reshape the future? And why is China at the forefront of this race? Let us step into this symphony of technology and industry to uncover the answers.
Technological Background and Breakthroughs: 6G’s Revolutionary Leap for IoT
If 5G laid the foundation for high-speed IoT connectivity, 6G is the catalyst that will propel this ecosystem to its zenith. Compared to 5G’s capacity to support one million devices per square kilometer, 6G elevates this to tens of millions, with exponential gains in spectrum efficiency and transmission speeds.
According to the latest research from the China Institute of Communications in early 2025, 6G will deliver ultra-low latency (sub-millisecond level) and exceptional reliability, enabling IoT devices to collaborate in real time even under extreme conditions. Equally significant, 6G’s low-power design will vastly extend the lifespan of terminal devices, meeting the demands of large-scale IoT deployments.
These breakthroughs unlock a realm of new possibilities for IoT. In smart cities, networks of tens of millions of sensors could monitor traffic, environmental conditions, and energy usage in real time; in industrial settings, 6G’s ultra-dense connectivity could drive smart manufacturing toward greater precision and efficiency.
The International Telecommunication Union (ITU) predicts that by 2030, the global number of IoT devices will exceed 50 billion, with 6G serving as the backbone of this ecosystem. China’s technological prowess and forward-thinking strategies are turning this vision into reality at an accelerated pace.
China’s Leadership in IoT and 6G Integration
In the global race toward 6G, China stands undeniably at the forefront. By 2025, Chinese research institutions and enterprises have already made significant strides in trials combining 6G with IoT. Guided by national policy, China has positioned 6G as a cornerstone of its “new infrastructure” initiative. As of April 2025, China boasts over 4.5 million 5G base stations—a vast network that paves the way for 6G development and deployment.
Meanwhile, tech giants like Huawei and ZTE have achieved breakthroughs in core 6G technologies, such as terahertz communication and intelligent reflecting surfaces, further solidifying China’s leadership in global telecommunications.
A striking example emerged in March 2025, when a Chinese research team unveiled a prototype of an ultra-low-power IoT terminal based on 6G concepts. This device not only achieved “integrated sensing and communication across air, land, and sea,” but also demonstrated stable performance in extreme environments like deep oceans and high altitudes.
This milestone is a testament to China’s innovation and a glimpse into 6G’s vast potential in IoT applications. China’s dominance is no coincidence—it stems from a potent combination of technological accumulation, a robust industrial ecosystem, and immense market demand. With the world’s largest IoT market and the most comprehensive supply chain, China is setting a new global benchmark.
Future Applications and Industry Impact
The deep integration of 6G and IoT promises a future that is nothing short of breathtaking. In smart cities, tens of millions of sensors will work in unison, optimizing traffic flow, reducing energy consumption, and even predicting natural disasters in real time.
In autonomous driving, 6G-enabled vehicle-to-vehicle networks will enable instantaneous communication, ensuring flawless coordination with zero errors. In industrial IoT, factory production lines will achieve full digitalization through ultra-dense connectivity, driving unprecedented gains in efficiency and resource utilization. These scenarios are not mere visions—they are transformative forces poised to reshape the global economic landscape.
Yet, opportunities come with challenges. The fusion of 6G and IoT will heighten security demands, making countermeasures against cyberattacks and data privacy breaches a top priority. Additionally, achieving global standardization and managing deployment costs will test international collaboration. Nevertheless, this tidal wave of change is unstoppable. With its technological edge and strategic foresight, China is well-positioned to define the rules of this game, propelling the global IoT industry to new heights.
China’s Power in Shaping the Future
The integration of IoT and 6G is more than a technological evolution—it is a redefinition of how humanity connects. In this global contest, China emerges as an unrivaled leader, wielding its formidable technical strength, vast market potential, and visionary strategies.
From enabling tens of millions of connections to pioneering integrated communication across all domains, every step China takes is writing a new chapter for IoT’s future. By 2030, when 6G enters commercial use, we may witness the dawn of a true “Internet of Everything” era—an era whose prelude is already resounding across China’s landscape. Stakeholders across industries must heed this trend, embrace the transformation, and join hands to paint a grand tapestry of technology and life.
Notably, amid this wave of IoT development, numerous enterprises are driving progress with innovative solutions. Take EELINK Communication, for example—a high-tech company with over 20 years of expertise in applying wireless communication technologies to IoT.
With a top-tier team, EELINK focuses on developing and manufacturing IoT hardware and software, offering products like remote monitoring platforms for temperature and humidity, and serving sectors such as asset management, vehicle theft prevention, insurance sales, and cold chain logistics.
Guided by a mission to “connect everything through intelligent technology,” EELINK is dedicated to delivering efficient, reliable solutions that meet evolving customer needs. Companies like these are vital contributors to the thriving IoT ecosystem, adding momentum to the industry’s growth.
