方法/步骤:
5g网络普及:
国内5G正式商用的时间节点是2019年10月31日,也是国内三大通信运营商首次公布5G商用套餐的日子,中国是5G发展最快的国家,某种程度上说,5G网络已经成为了一种普及化的基础设施。工信部发布的《2020年通信业统计公报》显示,截至2020年底,中国已开通5G基站超过71.8万个(当前已超80万个),5G网络已覆盖全国地级以上城市及重点县市。与之对应的,是GSA公布的截至2020年12月全球主要国家的5G基站数量——全球5G基站总量超过102万,其中:中国5G基站总量达到71.8万个;韩国基站部署超过12.1万个;美国5G基站部署量约为10万个;日本5G基站部署量超过3.5万个;德国5G基站部署量超过4.5万。预计2021年底,全球5G基站总量将超过210万,中国5G基站部署量将达150万。在5G领域,中国早已全面领先,走出了自己的道路,进入了普及阶段。但普及是指针对绝大多数城市和地区而言,个别代表不了全部。有可能部分城市和地区因为政策和投资的影响会优先发展,这都是很正常的。
况且这个是根据4G现有基站数量、覆盖率和5G基站更新速度得出的大致结论。5G由于频率较高,单个基站覆盖面积较小,因此如果不加大投入力度的话,是不会快于4G的普及时间的。但我国目前的经济体量与以往不同,政策与经济影响会加快这一进程,东部发达地区很可能2021年就已经搭上了快车。但由于5G是新技术,尚未完全成熟,在目前4G还够用的情况下,是没有必要着急换的。等一两年技术成熟后再购入5G手机是相对理性的选择。参考4G的普及时间,5G大概到2022年普及一二线城市,2023~2024年实现乡镇全覆盖。所以2020年换4G手机没问题的,用两年刚好换5G。目前存在5G手机溢价且5G信号覆盖不全等问题,等两年换最划得来。其实5G手机时代跟4G手机时代,在硬件上不会有本质的区别,更多是因为网络链接的变革而可以与物联网产生更多联系,这个起码要等到十年以后了。
当然,仅仅靠智能手机并不算真正的普及,5G网络完全运行最基本的硬件就是基站,而围绕着5G产生的一系列的配套生态,目前还不够成熟。基站建设费用高、功耗大、周期长。5G的特点是超高的传输数据速率。4G最高实现10Mbps的话,5G能够达到1Gbps,最高可达10Gbps。其次就是高可靠低延时,在此基础上,物联网、无人驾驶以及远程医疗将会迎来爆发。
