Driven by the Internet-of-Things (IoT)-enabled massively data-intensive applications, such as virtual-augmented-reality-based gaming, ultramassive machine-type communications, holographic rendering and high-precision communications, multiway teleconferencing, etc., there is a need for technological advancements and evolutions for wireless communications beyond the fifth-generation (5G) networks. The wireless data traffic is estimated to reach 4394 EB by 2030 (Source: ITU), and 5G will be unable to provide support to most of these advanced applications. Here, 6G is expected to extend the 5G capabilities to very high levels where millions of connected devices and applications could operate seamlessly with high data rates and low latency.

客座社论：利用6G实现大规模物联网的特刊：应用程序，架构，挑战和研究方向

在启用物联网（IoT）的大规模数据密集型应用的推动下，例如基于虚拟增强现实的游戏，超大规模机器类型通信，全息渲染和高精度通信，多路电话会议等，第五代（5G）网络以外的无线通信需要技术进步和发展。估计到2030年，无线数据流量将达到4394 EB（来源：国际电联），而5G将无法为这些高级应用程序中的大多数提供支持。在这里，6G有望将5G功能扩展到非常高的水平，数百万连接的设备和应用程序可以在高数据速率和低延迟的情况下无缝运行。
