Pathloss - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

How to Calculate Outdoor / Indoor Path Loss? Say at 2.4GHz and 5.8GHz.

Also Like to Know Different Material (Loss) Properties at 2.4GHz / 5.8GHz Band.

fudged free air path loss

PL = 20 log(f) + 20 log(d) - Gt - Gr - 27.6

f = frequency in MHz,
d = distance in meters between Tx and Rx antennas
20 log(F) = gain of a isotropic receiving antenna
Gt, Gr = antenna gains of the transmitter and receiver antennas.
