在天线测试中RSSI什么意思啊？
请各位指教！

难道是 recieved signal strength indicate?

就是在手机天线测试中用的
可能是！
谢谢了

RSSI is Received Signal Strength Index and means Signal Noise Ratio (SNR). So RSSI = Received Radio signal/ Noise. Foe ex, at 11a mode, If signal strength is -35dbm and Noise floor is -85dbm, then RSSI is 50dbm.
Usually it present as % in most case.

无绳电话经常测试RSSI的灵敏度,RSSI的灵敏度太高意味着在超过合理的通信距离(信噪比)仍然不能关机

loss=TxPwr/NL*RSSI,其中TxPwr是发送节点的发送功率，NL是接收节点的本地噪声水平

照楼主这么说。RSSI不就变成了SNR?
