What is the calculated EIRP for AP2 given Ptx 13 dBm, antenna gain 12 dBi, and 3 dB cable loss?

Explanation:
EIRP is the transmit power that effectively radiates in the strongest direction, combining the transmitter power, the antenna gain, and any losses in the feedline. Compute it by adding the transmit power in dBm to the antenna gain in dBi, then subtracting cable/feedline loss in dB. Here, 13 dBm + 12 dBi − 3 dB = 22 dBm. So the calculated EIRP is 22 dBm, matching the 22 dBm option.
