Recently, the topic of 6G has frequently topped the trending searches. From CCTV News to State Council press conferences, from the nationwide discussion of "6G network is coming" to the government work report listing 6G as a key future industry to be cultivated, this once distant term is approaching us at an unexpected speed.
Many people ask: 5G has only been around for a short time, so what exactly will 6G bring? Is it just faster internet speeds?6G is more than just "faster"6G, or sixth-generation mobile communication technology. Looking back, each generation of mobile communication upgrades has brought about a leap forward in technology:
1G gave us mobile phone calls
2G made text messaging possible
3G brought about the beginnings of the mobile internet.
4G spurred the explosion of live streaming, short videos, and mobile payments.
5G is making smart factories and autonomous driving a reality.
6G will be a leap from "Internet of Everything" to "Intelligent Internet of Everything".
If 5G is a broad information superhighway, then 6G is like a "super intelligent network" covering air, land, sea, and air. It is no longer just about "faster network speeds," but a comprehensive transformation—integrating communication, sensing, computing, and intelligence to become a key infrastructure supporting the development of the digital economy.
First, it runs faster.
Mobile communication relies on electromagnetic waves to transmit information; the greater the bandwidth, the faster the network speed. 6G will use millimeter waves and even higher frequency bands such as terahertz, with bandwidth potentially more than ten times that of 5G.
Recently, a research team from Peking University and other institutions proposed a "fiber-wireless converged communication" technology that enables seamless integration of fiber optic and terahertz wireless communication. The single-channel transmission rate in the experiment reached hundreds of Gbps—meaning that a 4K ultra-high-definition movie can be downloaded in less than one second.
Second, it allows for a clearer view.6G base stations and signals are not only "communication tools," but also possess radar detection and imaging capabilities. Terahertz waves have high frequencies and short wavelengths, acting like a more precise ruler, capable of not only determining direction but also accurately measuring distance.
By analyzing the reflected signals from targets, 6G networks are expected to achieve centimeter-level or even sub-meter-level high-precision perception. This will give drones and autonomous vehicles more acute "digital senses," allowing them to better "see" road conditions and flexibly avoid obstacles.
Third, become smarter.
Traditional networks are only responsible for sending and receiving data, requiring the data to be transmitted to a remote cloud computing center for processing. In contrast, 6G signal base stations possess local AI computing capabilities, enabling them to "think" independently and provide personalized, empathetic, and intelligent services in a timely manner.
In the words of industry insiders, 6G will achieve "ubiquitous network coverage, ubiquitous computing power, and pervasive intelligence."Three major convergence trends of 6G
At a deeper level, 6G represents three major convergence trends:
Integration with AI:On the one hand, there is "AI for 6G"—using AI technology to optimize network performance and improve operational efficiency; on the other hand, there is "6G for AI"—using 6G networks to provide a better connectivity experience for AI applications, enabling scenarios such as autonomous driving and autonomous collaboration of medical devices to truly take root.
Fusion with perception:This is what is now commonly referred to as "sensory integration." 6G can not only communicate, but also sense the surrounding environment like radar, accurately detecting the position, speed, and shape of objects.
Integration with computing power:The networks of the future will transmit not only data, but also computing power. 6G networks will become a "computing power network," allowing users to access the computing resources they need anytime, anywhere, just as conveniently as they use electricity today.
How far away is 6G from us?After seeing these "superpowers," you might be eager to try them out. So, when exactly will 6G be available? According to current plans:my country has completed all technical trials in the first phase of 6G and has accumulated more than 300 key technology reserves.
Next, we will focus on developing 6G standards and building test networks.
It is expected that 6G will be commercially available around 2030.
In other words, it will be about five to six years before we actually use 6G.
6G will usher in a new era: holographic projection meetings, drone delivery, and "digital clones" to explore the virtual world... These scenes, which once only existed in science fiction movies, are becoming a tangible reality.
It is not a simple upgrade of 5G, but a comprehensive leap from "connectivity" to "sensing", from "ground" to "space", and from "transmission" to "intelligence".
The future is here; the era of the Internet of Everything is rapidly approaching.
