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：关于通过 6G 实现大规模物联网的特刊：应用、架构、挑战和研究方向


在物联网（IoT）驱动的海量数据密集型应用的推动下，例如基于虚拟增强现实的游戏、超海量机器类通信、全息渲染和高精度通信、多路电话会议等，第五代 (5G) 网络之外的无线通信需要技术进步和演进。预计到 2030 年，无线数据流量将达到 4394 EB（来源：ITU），而 5G 将无法为大多数此类高级应用提供支持。在这里，6G 预计将 5G 功能扩展到非常高的水平，使数百万个连接的设备和应用程序可以以高数据速率和低延迟无缝运行。
