$高通(QCOM)$早在2016年10月高通就发布了首款5G基带—x50，预计2018年上半年搭载x50的终端会上市。实际整整晚了一年才上市。市场曾一度以为x50不会进入现实世界。x50基带采用28nm工艺，仅支持5g制式，需要外挂。今天的手机不得不加大电池和尺寸去容纳x50和它的天线以及热量。现在x55基带也已发布，至于何时上市，高通还没有说。

网上所说的5g应用我不太赞同。什么远程手术，手术室为什么不用Wi-Fi和有线网络？成本更低更稳定。什么车联网，现在的5g信号肉身都能挡住。汽车那么快，还有铁皮，保持连接很困难，除非每个路灯都有基站。
5g的建设成本太高了，中国在这方面世界领先。美国那边还没有大规模建设，军方正在退频谱资源。那么多基站要建设，想想就头大[汗颜]

（我一换行手机就卡的不行，app有问题）以下是个人看法。5G肯定会到来，但什么时候来很难说。现在的5g不成熟，市场还不能提供有竞争力的5g产品。5g波长更短，频率更高，衰减快。5g基站覆盖范围小，需要更多的基站，比4g基站密度多得多。现在的5g基站功耗高的要命，空载都降不下去，大概是4g基站功耗的2-3倍。5g没有达到消费者的期望，峰值速度和延迟比宣传的差。
等待大回调

x50就一面子工程，x55才是完整版。
