Sorry for this basic question, I have no experience with wireless issues, but I am learning and trying to understand the theory of antennas:
My question is what is the FSL really means?
I cam to know that FSL = 36.6 + 20 LOG F + 20 LOG D
For 5.8 GHZ and 14 miles this would yield a 133.86 db, now is this133.86 is attenuation? Is it related to the receiver sensitivity at the destination? How can I use this number?
Let me think loud, I understand it this way
If I have EIRP of 36 dB in the transmission end, then this 36 db will be subtracted from the 133.86, hence I will get a -97.86 db, so my receiver should be sensitive enough to receive a power of 1.99 e-10 Watts.
