美国“5G”网络又遇尴尬，网速还没4G快！
从去年开始，关于5G网络的讨论就一直没停过。所以到了今年，很多科技公司也是亮出了他们的5G网络，并且宣布将在今年推出5G网络服务。可见，5G的竞争也是异常激烈，不管是国家之间，还是各国的电信运营商，都想着挣个第一。
作为世界科技大国之一的美国，自然也是不甘落后。比如，美国运营商AT&T曾首发了“5G”网络，一时引起了业内的轰动。AT&T表示，只要是使用AT&T服务的最新安卓手机，就可以用体验到“5G”网络了。不过后来却出现了尴尬场面，有用户发现这并不是真正的5G网络，依然是4G网络，那是怎么回事呢？
事实上，AT&T的“5G”网络只是一种4G的升级版，什么首发5G只是虚头罢了，看来不止是国内的运营商爱玩游戏，国外也是一个样。不过这还没完，最近有调查显示AT&T的“5G”还不如其它运营商的4G网络快，可谓把AT&T的脸给打肿了。
一家名为OpenSignal机构表示，AT&T的“5G”网络速度为28.8Mbps，Verizon的网速则达到了29.9Mbps，T-Mobile为29.4Mbps，连同行的不都及。而我们国家的4G网络目前更是达到了80.44Mbps，远比美国快了不少，可见AT&T的“5G”网络都没有4G的快呢！
总的来说，AT&T的“5G”本质上是4G技术，而AT&T这样做的目的也是为了吸引到更多的用户，个人觉得这样的手段并不高明。反观华为的5G，是目前真正意义上的5G之一，虽然处于世界的领先地位，但经常被挑出问题。说到底也是经济利益，毕竟华为的5G设备质量和性能都很不错，成本也是最低的，这更使得很多运营商都无法抛弃华为。
