Q: 20
You are doing tests in your lab and with the following equipment specifications
• AP1 has a radio that generates a 10 dBm signal
• AP2 has a radio that generates a 11 dBm signal
• AP1 has an antenna with a gain of 9 dBi
• AP2 has an antenna with a gain of 12 dBi.
• The antenna cable for AP1 has a 2 dB loss
• The antenna cable for AP2 has a 3 dB loss
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for APT?

Option C similar question came up in practice labs. Official guide has good EIRP calculation examples.
C , because for AP1 you just add up the radio power (10 dBm) and antenna gain (9 dBi) then subtract cable loss (2 dB), so 10 + 9 - 2 = 17 dBm. Pretty sure that's the EIRP formula, correct me if I missed something.
C or B. Had something like this in a mock and went with B that time.
