Could you kindly explain me or advise following please...
I have a TP-link WiFi router. When I measure signal strength just in the vicinity of the router- literally I touch my smartphone (with WiFi signal strength measurement application) to a WiFi router antenna - I get signal strength -15dBm. The manufacturer datasheet says - "WiFi transmission power <30dBm".
So why do i have -15dBm then just at immediate vicinity of the router ? Where does 45 dBm go? (from 30 dBm down to -15)
Thank you so much.
