不过本篇文章成文之前（11/15）收到一个坏消息，就是美国运营商AT&T关停NBIoT网。引起业界一片哗然。另外一个NBIoT的大运营商NT Docomo也已经于2020年关停并退出。这可以看做5G最为寄以厚望的用例之一的一个挫折。因为作为万物互联的愿景平台，5G需要更多类的用例运行其上。这个消息可参考：https://www.linkedin.com/posts/naumann_nbiot-3gpp-ltem-activity-7263282035463532544-U46E
由于无线网络需求不断增长，基于万物互联 (IoE) 的智能服务越来越受欢迎。这要求对具有增强性能的无线网络进行评估，作为下一代通信系统。尽管5G网络显示出支持众多基于IoE的服务的巨大潜力，但它不足以满足新智能应用的全部要求。因此，人们越来越需要设想6G无线通信系统来克服现有5G网络的主要限制。此外，在6G中融入人工智能将为与网络优化相关的非常复杂的问题提供解决方案。6G无线通信的要求是支持大量数据驱动的应用和不断增加的用户数量。
移动蜂窝网络演进如下，也可参考本公众号其他6G系列相关的文章内容：

每一代无线通信网络的发展都会对现有技术进行增强，并增加新功能以满足未来的需求。尽管5G通信系统显示出良好的特性，但仍不足以满足不断增长的无线通信需求。这些因素要求我们设想6G网络，以有效满足新时代通信系统的需求。
坐而论道，好好读书！
