Hello,
Can anybody explain math behind result of this qestion for wireless newbie? What is the simpiest way to solve this situations and how i can solve similiar real life situations like this? I understand what is dBm in reference to mW (or lets say how to conver that) what is dBi and cable loss however i dont see logic behind this.
How signal from transmitting 28dBm (631mW) can appear on other side as -45dBm. (0,0000316mW) when i tested this in real life i litterary put my device on the ap sticking them together and RSSI on device still were -25dBm at best. Is there such a big loss when only distance is plastic separating device and ap?
Keith Barker introduced wery simple math of converting dBm to mW (06- dBs and Watts - 200-355 CBTnuggets) is it possible to apply his math on this example?
Sincerely Michal
