# 4G 信号强度定义
中国电信的外场测试标准如下:
近点 SINR>=25DB,RSRP>=-85dbm;
中点:-85dBm>RSRP>=-95dBm, SINR>=15dB;
远点为RSRP<-95dBm
根据中移终端外场测试规范LTE信号点位的选择为
极好点 RSRP>-85dBmSINR>25
好点RSRP=-85-95dBmSINR:16-25
中点RSRP=-95-105dBmSINR:11-15
差点RSRP=-105-115dBmSINR:3-10
极差点RSRP<-115dB;SINR<3
中国联通外场测试标注定义

中点RSRP=-85-95dBmSINR:5-15DB
远点RSRP=-95-110dBmSINR<5DB
