Using AP1 specifications, what is the calculated EIRP?

• A. 26 dBm
• B. 30 dBm
• C. 17 dBm
• D. 0.12 dBm

Answer: (C)

EIRP represents the power that appears to be radiated in the strongest direction, calculated by adding the transmitter power (in dBm) to the antenna gain (in dBi) and subtracting any feedline losses. For AP1, the specified transmitter power is 15 dBm and the integrated antenna provides 2 dBi of gain. With no additional losses, EIRP = 15 dBm + 2 dBi = 17 dBm. If there were cable or feedline losses, the value would be lower (e.g., 1 dB loss would give 16 dBm). This is why 17 dBm fits the AP1 specifications.
