1. The problem statement, all variables and given/known data I have a 2 wireless cards with a power output of 0dBm, two 5dBi gain antennas, and a 30dB attenuator connected to each antenna. I need to figure out what the path loss will be in this scenario, so I can therefore determine the maximum distance possible between the antennas before they can no longer receive each other's signal. 2. Relevant equations I know path loss in dB: L = 20 log_10(4 * π *d / λ) this one I can use to find the max distance once I know L, but I don't know how to find the path loss due to the attenuation in the first place. 3. The attempt at a solution I know attenuation is: = 10 * log_10(power out/ power in) so 30 dB = 10 * log(power out/ odBm) How can I find power out from here? And how could I use that in the path loss equation? Thank you for the help.
