While 5G research is maturing toward a global standard, the focus has now shifted toward the development of beyond 5G solutions. Wireless data traffic is estimated to reach 4394 EB by 2030 (Source: International Telecommunication Union), and the number of connected devices might surge beyond 50 billion. 5G will be unable to provide adequate support for various applications that depend on this huge data generated from massively interconnected devices. Many future data-intensive applications and services like pervasive edge intelligence, holographic rendering, high-precision manufacturing, ultra-massive machine-type communications, and virtual/augmented reality (VR/AR)-based gaming are expected to demand higher bit rates (terabits per second) and lower latency (less than 1 ms). Here, 6G is expected to extend 5G capabilities to higher levels where millions of connected devices and applications could operate seamlessly with trust, low latency, and high bandwidth. Research in 6G has already begun and is expected to gain momentum very soon. Industries and academia have allocated enormous funds and other resources for 6G research and development. The main focus is expected to be in the deployment of 6G-enabled massive Internet of Things (IoT), interoperability issues, system architectures, energy-efficient technologies, and application of artificial intelligence and other novel techniques to improve network performance, security, and privacy.

特邀社论：6G：未来无线通信的范式

虽然 5G 研究正朝着全球标准发展，但现在的重点已转向开发 5G 以外的解决方案。预计到 2030 年，无线数据流量将达到 4394 EB（来源：国际电信联盟），连接设备的数量可能会激增至 500 亿以上。5G 将无法为依赖于大规模互连设备产生的海量数据的各种应用提供足够的支持。许多未来的数据密集型应用程序和服务，如无处不在的边缘智能、全息渲染、高精度制造、超大规模机器类型通信和基于虚拟/增强现实 (VR/AR) 的游戏，预计将需要更高的比特率。 TB 每秒）和更低的延迟（小于 1 毫秒）。这里，6G 有望将 5G 功能扩展到更高水平，使数百万连接的设备和应用程序可以在信任、低延迟和高带宽的情况下无缝运行。6G 的研究已经开始，预计很快就会获得动力。产业界和学术界为 6G 研发投入了大量资金和其他资源。预计主要重点是部署支持 6G 的大规模物联网 (IoT)、互操作性问题、系统架构、节能技术以及应用人工智能和其他新技术以提高网络性能、安全性和隐私。产业界和学术界为 6G 研发投入了大量资金和其他资源。预计主要重点是部署支持 6G 的大规模物联网 (IoT)、互操作性问题、系统架构、节能技术以及应用人工智能和其他新技术以提高网络性能、安全性和隐私。产业界和学术界为 6G 研发投入了大量资金和其他资源。预计主要重点是部署支持 6G 的大规模物联网 (IoT)、互操作性问题、系统架构、节能技术以及应用人工智能和其他新技术以提高网络性能、安全性和隐私。
