OTA的主要测量指标OTA测量包括发射端测量和接收端测量两个部分。发射端测量指标主要包括以功率测量为主的指标，如TRP(辐射功率)和以信道质量为主的指标如DirectionalEVM；接收端测量指标主要包括波束顶点处的灵敏度，交调，Throughput(吞吐量)等。具体如下：发射端：ACLR邻道泄漏功率比TRP辐射功率EIRP等效全向辐射功率，即某方向测得的辐射功率，为TRP的基本构成单位DirectionalEVM具有方向性的矢量误差幅度DirectionalPower具有方向性的功率-接收端：TIS全向灵敏度EIS有效全向灵敏度，即某方向测得的灵敏度，为TIS的基本构成单位。

据悉，2017年*计划90万个充电桩投入使用，到2020年建成450万个充电桩，充换电站数量要求达到1.2万座。可见，充电桩的“火热缺”是电网近年来“头痛”的问题。然而，2015年12月相关部门发布的新修订电动汽车充电接口及通信协议5项*标准是否完全使得充电桩行业的问题迎刃而解？在兼容性方面，交直流充电接口型式及结构与原有标准兼容，新标准修改了部分触头和机械锁尺寸，但新旧插头插座能够相互配合，直流充电接口增加的电子锁止装置，不影响新旧产品间的电气连接，用户仅需更新通信协议版本，即可实现新供电设备和电动汽车能够保障基本的充电功能。
