美媒:别指望苹果 2020年才会有5G版iPhone

网易科技 2018-08-22

  5G时代即将到来,这已经是个“板上钉钉”的事实了。据美国媒体报道,近来人们一直谈论下一代移动通信,而2018年也将出现首批商业部署的5G网络,即使范围非常有限。明年首批5G智能手机将上市,三星已经在开发这种设备(但不是Galaxy S10),Sprint和LG也在合作开发。但不要指望苹果会很快推出5G版iPhone X。

  从4G LTE出现时人们就看到苹果的做法,该公司是等到运营商真正提供大面积覆盖后才发布首款4G版iPhone,那就是iPhone 5。该手机是在Android版LTE手机出来1年多才上市。而早在2007年iPhone刚面世时,甚至都不支持3G。换句话说,不要期望明年会有5G版iPhone,最早也要到2020年。预计Android厂商也不会大量推出5G设备。

  Digitimes的最新报道称,虽然5G手机明年就会出货,但直到2021年才会加快普及。然而,预计到2022年5G手机将占5G高端设备出货量的97%,届时约五分之一的新手机将支持5G。报道没有提及iPhone,但苹果到那时也会让所有iPhone支持5G。Digitimes提到一些手机制造商安装5G芯片需要解决的问题,但与运营商的支持无关,主要是天线设计和能耗。

  由于5G手机支持毫米波通信,受波长的限制,信号会被障碍物影响,因此需要配置4-8个天线阵列加强信号接收能力,在生产上会遇到设备尺寸和能耗上的技术障碍。换句话说,包括苹果在内的手机制造商将必须确保设备提供可靠的5G连接,5G不能成为电池续航能力的杀手。

  人们或许还记得2011年4G刚出来时真的很费电,得益于技术进步逐渐解决了这个问题,但花了比较长的时间。当然,前几年的信号覆盖也是一个问题。在移动运营商的5G网络覆盖更多地方前,手机厂商没什么动力去销售5G设备,在所有市场部署5G需要花些时间。
