Refer to the exhibit. A network engineer needs the far end of a wireless bridge to receive at -45dBM. Based on the diagram, what value in dBm must the transmitter use to send to achieve the desired result?
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
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
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
