Thanks a lot for your sharing. I think I figured out as well. I was confused the relationship between RSSI and Received Power, as several reference reveal there is no relationship between RSSI and power level, such as wikipedia. So I wonder the Signa...

Thanks for your agreement. According to your question, the EIRP would be -13dbm - 1db + 2dbi = -12dbm. However, I wonder what is the RSSI measured right at the antenna. If there is any misunderstanding, please let me know.

Thanks a lot for your explicit explanation on the terms used in Wi-Fi. Only one thing I'm confused is in the section How to find EIRP 802.11a EIRP = 17dBm (40mw) - 0dB + 6dBi = 23dBm = 200mw of actual output power 802.11bg EIRP = 20dBm (100mw) - 0dB ...
