For perspective, you might use/see a 69-dB Wi-Fi loss over a distance of about 13 to 28 meters. Reference: CCNA-Wireless-200-355-Official-Cert-Guide, page 22 Transmit Tx power - 4dB + 2dBi - 69dB +2dBi - 4dB = -45dBm Transmit Tx power = -45 + 4 -2 + 69 -2 + 4 = 28 bBm

someone know how to resolve this question? I think that the value of free space path loss is missed too.

Fully agree with xtrattitude4u, we missed -69dB for free space path loss.

Since the diagram gives no value for the free space path loss, you can't answer the question as it is shown. Assuming 28dBm is actually the correct answer, the free space path loss must be -69db: 28dbm - 4dB + 2dBi - 69dB +2dBi - 4dB = -45dBm
