全球首个 5G 网络标准正式签署，预计将会在2019 年上线

5G 会有多快？

伴随 4G 通讯市场的普及，包括 AT&T、Verizon 和 T-Mobile 在内的各大运营商都着手准备 5G 网络的试运营。不过一直以来对于 5G 信号却没有统一的标准评判，日前 3GPP 在葡萄牙里斯本召开的一次会议上，终于正式签署通过了 5G NSA（Non-Standalone）标准的第一个版本。该标准规定 5G 网络要对包括低频（600MHz 及 700MHz）、中频（3.5GHz）和高频（50GHz）等频段进行支持。与此同时网上还指出，5G Standalone 标准或将会在明年 6 月签署通过，相信在有了统一的标准后，新版的计划或将会在 2019 年正式上线，你准备好迎接了吗？
