<p>5G是最新一代蜂窝移动通信技术，也是即4G（LTE-A、WiMax）、3G（UMTS、LTE）和2G（GSM）系统之后的延伸。5G的性能目标是高数据速率、减少延迟、节省能源、降低成本、提高系统容量和大规模设备连接。Release-15中的5G规范的第一阶段是为了适应早期的商业部署。Release-16的第二阶段将于2020年4月完成，作为IMT-2020技术的候选提交给国际电信联盟（ITU）。ITU IMT-2020规范要求速度高达20 Gbit/s，可以实现宽信道带宽和大容量MIMO。2019年10月31日，三大运营商公布5G商用套餐，并于11月1日正式上线5G商用套餐。</p> </div> <div class="list"> <div class="list-box">  <div class="list-chi"><div class="href"><a
